Probably closer than you think. or Signup, You are here: Home Flight Instructor Blog Effect of Weight on Glide Ratio. It is good to know what your "best" glide ratio is, such as most single engine training airplanes are in the 9:1 glide ratio. When introduced, it featured wood-spar wings and oleo-shock main gear. Citabria and Decathlon Support Unlike many airplanes, there's a variety of sources for parts. Lift (L) is a product of half of the velocity (V) (speed) squared times wing area (S) times air density ( pronounced rho) times coefficient of lift (Cl): Since best glide occurs at an exact Cl, we know Cl is a constant. 15:1 from 2000 feet gives a distance of 30000 feet or about 6 miles. 3, 2005.) Yippee! I asked Charlie if I could come back just to play. View photos, ownership, registration history, and more. That model was abandoned by aerobatic enthusiasts in favor of the Champion Decathlon 8KCAB because of its better inverted flight performance. A-759. 91 or F.A.R 135. On this Wikipedia the language links are at the top of the page across from the article title. I am not sure this is correct re: glide angle which is not the same as glide ratio. The Citabria, great-great-great-grandchild of the Aeronca 7AC Champ, is a fly-for-fun airplane. 7ECA, Citabria Standard, Citabria Aurora. This means that all else being equal a sailplane can stay in the air for about two to three times as long as a hang glider! The C172S will descend at about 760 feet per minute. I also know there is a direct relationship between AOA and airspeed. Formally Quest Aircraft, the Daher Kodiak 100 was first introduced in 2008 as a rugged off airport single engine turboprop aircraft. altitude) have no effect on the glide ratio. (You must log in or sign up to reply here. Fuel Capacity: 36 gal. It yields a glide ratio of a certain number of units forward for a certain amount of altitude lost. And, on a side note, do any of you happen to know the glide ratio for a 7GCAA? The Explorer likes to fly. To emphasize a glider term, sink rate matters. Usable) Oil Capacity: 8 quarts Baggage Capacity: 100 lbs. The glide ratio varies with air speed, but there is a maximum value which is frequently quoted. What else should I plan for, in checking this? If you have a GPS just hold an airspeed, throttle back, decend a fixed amount and see how far you went. The model 7ECA Citabria entered production at Champion in 1964. We use cookies to help you get the best experience when using our website. If the weight is reduced and the IAS held constant, the glide angle will: Well I stuck my neck out on this one. The Citabria design based on the Aeronca 7AC Champion. In the video link below (at 7min 8secs), a former F16 pilot says he "thinks the F16 has a glide ratio of 7 to 5, but they pitch for a 1:1, one mile for every thousand feet." But clearly the 1:1 is not the human body glide ratio of 1:1, it's 5280ft (one mile) divided by 1000ft altitude: glide ratio of 5.28 You could carry 5000 extra lbs of lead and still glide to the same touchdown point. Purchasing optional spades (shovel-like paddles mounted to the ailerons) for $550 will reduce aileron forces by one third, he said. The 7GCAA . $10.00. I would like to know the actual glide ratio of my airplane at several combinations of configuration and airspeed. TO OUR GLIDE RATIO (AND ITS RESULTANT GLIDE SLOPE)? Eventually, the Citabria line expanded to four models. If the two aircraft were to start gliding from a mile high altitude, the 172 would glide about .8 miles further than the phantom. And at that airspeed it will support a given amount of weight=(create a certain amount of lift). Does the extra weight provide the extra energy to offset the extra drag? Solo Date: November 19, 2022. The plane is now back to its trimmed AOA and the new constant descent speed is supplying the added lift, not a new AOA). It was substantially similar to the 7GCAA of the same year, with a Lycoming O-320-A2B engine of 150 horsepower (110kW), wood-spar wings, and spring steel main gear legs. While the Citabria designs remain successful, and the introduction of the 7KCAB variant of the Citabria had added limited inverted flight capability, the Citabrias are not capable of "outside" maneuvers, those requiring significant negative-g loads. I'll bet there are some out there. Ceiling: 17,000. This describes me. An aircraft has a single best glide speed for a given configuration. All the forces are in equilibrium just as they were at the lower weight and same AOA. Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from +5g to -2g. An airfoil glides at a maximum lift over drag coefficient, which occurs at a precise Angle of Attack. This should be a indicated airspeed you should try and maintain the second your engine quits or starts sputtering. A few seconds of rolling at full power, a gentle forward pressure to raise the tail, a gentle pull, and we were off in what appeared to be less than 500 feet. Custom Doggy Mat. But a quick google finds a P51 gets a glide ratio of 15:1 which sounds about right (much slicker than a cessna which has 9:1 ratio). SECOND THE SPEED VARIABLE: I know the AOA did not change. The angle to the left wing from the pilot eyes is around 5.4 degrees. The Glide Ratio is the ratio of distance forward to distance downwards when a glider is flown at a constant speed in still air. Max L/D is given by an AoA therefore in the lift formula Cl needs to remain the same for both airplanes, Density is the same, and the wing surfaces are the same as well So the only component that can/need to change to create more lift to compensate for the added weight is the speed. 8-10:1. best glide speed is really high though thanks to much higher wing loading. No one expects an air cooled 160hp with a carb. The fuselage and tail surfaces are constructed of welded metal tubing. It's not a fixed number and the 50:1 ratio will only be achieved at one speed. The 2-33 first flew in 1965 and production was started in 1967. Bellanca Citabria 7GCBC. https://en.wikipedia.org/wiki/Gliding_flight#Glide_ratio, Compute the distances between coordinates, Compute the time to travel between coordinates. The Mach 0.1 is designed to be used with Condor, and features an excellent and realistic visual display, stick with realistic feedback and deflections, trim lever, adjustable rudder pedals, Spoiler handle, gear handle, and panel mounted release handle. Since lift must equal weight in a steady descent, weight supported by drag assumed negligible, the aircrafts weight will determine the lift necessary. TO OUR GLIDE TIME? An ILS approach, with a 3 degree glideslope requires an 18:1 glide ratio. The outer shape of the fuselage is created by a combination of wooden formers and longerons, covered with fabric. Champion switched to spring steel main gear legs in 1967. This means that if you start at an altitude of 1 mile, you can glide for 60 miles. It's easier from the back seat, but that's not where you solo this aircraft. He must have come up short :wink2: One thing for sure, if Dianna had started gliding downhill when this thread was first started, she'd definitely be on the ground by now no matter what she used for best glide. N574KS, Glider: GrobG 102 Astir CSTail #: . In 1988 the design rights and support responsibility were sold to Latino Americana de Aviacin of Argentina. GlobalAir.com is your partner in connecting you with relevant information and resources. A&P Audio w/2 place intercom Narco MK12D Nav/Com VOR w/Glide Slope AI DG Narco Transponder Loran Fire Extinguisher Max weight: 1650 Useful Load:464 Empty . It is also certified for aerobatic flight. The 7GCAA and 7GCBC variants, added in 1965, were joined by the 7KCAB in 1968. Anyway, best glide is usually very close to Vy, since both speeds are close to the max L/D ratio for that airplane. So what does all this gibberish mean, right? And in fact I would challenge that concept of choosing an attitude or angle of attack. In 1967, Champion switched to spring steel main gear legs; by then, the Lycoming engine had become the standard. "It reduces a lot of problems," Mehlhaff, Jr., said. This should be your "standard" landing. Steve Fossett was flying a Bellanca-built Super Decathlon when he went missing on September 3, 2007. The electrical system is 12 volts, direct current, using the airframe as a negative ground. twins are probably in the same range for engine out L/D i.e. Demonstrated Crosswind Component: 17 kts. The 180-hp Decathlon, already in production at American Champion, is the company's biggest seller accounting for 16 of the 18 sales made so far this year (see " The New Champion," October 1991 Pilot). The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. BUT Fuel is supplied from two interconnected wing tanks and is gravity fed to the engine carburetor. The prototype had an open cockpit for a single pilot, but the design allowed for conversion to a two seat layout. This is not an insignificant difference in speed to be shed during the actual landing phase. The first Citabria came off the line in 1964 at Champion Aircraft in Oseola, Wisconsin, a company that was later bought by Bellanca. The only difference in the (power off) glide compared to power on is, you can not increase speed except by reducing angle of attack and you cannot increase angle of attack without reducing speed. I do most every landing with engine idle, so I obviously know the drill. Gliding is a descending, opposite of climbing, which is ascending. Aircraft.com is the leading registry for planes, jets, and helicopters. the heavier plane will reach the ground faster. Remains of the plane were found 13 months later near the town of Mammoth Lakes, California, just south of the original search area. Wow! The airplane is approved for day and night VFR operations when equipped in accordance with F.A.R. Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from . The fuselage and tail surfaces are constructed of welded metal tubing. In comparison, a Boeing 747 has a 15:1 glide ratio. Decathlons and Super Decathlons remain popular as aerobatic trainers, as beginning and intermediate aerobatic aircraft, and as personal aircraft. Demonstrated Crosswind Component: 17kts. The heavier the aircraft is, the higher the airspeed must be to obtain the same glide ratio. The DA40 can do about 11:1 at lower altitudes, and gets better the higher you go (true of any airplane, due to higher TAS at altitude maintaining Vg IAS). Fuel Burn at 75% power in standard conditions per hour. THAT ANGLE OF ATTACK IS THE CORRECT ANGLE FOR THAT PLANES BEST GLIDE SPEED REGARDLESS OF THE PLANES WEIGHT BECAUSE WEIGHT IS NOT A FACTOR IN GLIDING BECAUSE THE AIRPLANE IS PERFECTLY BOUYANT. I believe the 172 is 9:1 and the 182 is 10:1. Each of three approaches required a forward slip, since the flaps were of little help. Will both airplanes arrive at the same point? The 7GCAA was basically the same as the 7ECA, but with a 150-hp engine. In GA aircraft, the speed is given in reference to the max weight. Wing aspect ratio: 6.72; Length overall: 22 ft 8 in (6.91 m) Height overall: 7 ft 0 in (2.13 . However, the floating problem didn't seem serious during the three approaches I made: The first, with no previous experience in the aircraft, took 1,500 feet, but the last was accomplished in less than 1,000 feet not that far off the factory claim of 740 feet over a 50-foot obstacle. Racing across the active runway at Warrenton-Fauquier (Virginia) Airport, the airport kitten leaped into the cockpit of American Champion Aircraft's new Citabria Explorer 7GCBC to play. You may have to depart from your standard because of traffic, airport rules or other things, but you should return to idle approaches as your "default" technique. 3. This page was last edited on 4 November 2022, at 14:52. Dec 19 2022. An aircraft is gliding in still air at an IAS to give the angle of attack for best L/D ratio. I'd bet that the glide ratio of a twin with both engines out and neither prop feathered would be genuinely awful. So.., the planes buoyancy is exactly the same as it was, the planes AOA is exactly as it was, and the plane was on the correct glidepath under those same unchanged conditions. Aircraft Serial Number1335-2002. Since it is the lift over drag (L/D) ratio that determines the gliding range, weight will not affect it. N20737, Glider: HoltzMach 0.1 SimulatorTail #: 13:1 with the prop stalled, MAYBE. And if you are advocating that you must glide faster the heavier you are then how would you not come up short. ? 4 products. Perfect equilibrium. Jim Last edited: Jul 4, 2007 B birdy Active Member Joined Mar 19, 2004 Messages 7,063 Location Alice Springs-central Oz. So if I were at 10000 feet and lost all my engines, I could expect to glide about 30 miles. American Champion's 7GCBC, reintroduced in 1994 as the Citabria "Explorer," is similar to earlier versions, with the exception of the metal-spar wings and the use of the Lycoming O-320-B2B of 160 horsepower (120kW); the most recent significant design change has been the switch to aluminum main gear legs in 2004. Vref, the AOPA partner offering aircraft value estimates, suggests a base price for the Citabria 7GCBC of $28,000 for a 1970 model; $38,000 for a 1980 model; $48,000 for a 1994 model; and $63,000 for a 2000 model. :) keep up the good job. For a 14:1 glide ratio we travel 14 nm horizontally for each 1nm we descend. Bellanca built over 600 of the 8KCAB design before production of the aircraft was interrupted when the company's assets were liquidated in 1981. The aircraft was powered by a 200hp (150kW) Lycoming IO-360 Special engine driving a two-bladed propeller. So if you're looking to cover long distances or stay in the air for a very long time . You have to explain that a little better than that. rather than 7.01 or 5.01 ? Yes, L/D is L/D always. What does glide ratio mean? Takeoff Distance Over 50-ft Obstacle: 895 ft. The 7GCBC Citabria was used as an observation aircraft by the Turkish Army. Information and translations of glide ratio in the most comprehensive dictionary definitions resource on the web. This speed is important as it represents the bottom of the drag curve. Center of cabin to wing tip 16.75 feet. An "Ultimate Adventure" version, with a Superior Vantage O-360-A3A2 engine of 180 horsepower (130kW) and a composite propeller, is also produced by American Champion. Both of them start a power off descent at the same time at the same position. They also now manufacture the Citabria Adventure and the Citabria Explorer. Both aircraft will cover the same distance but the lighter one will take a longer time to do so. 45 and 45 is what I was told. I couldn't find a glide ratio for a spitfire. Mark, not exactly. How far they go forward versus how much they drop is the glide ratio. The extra weight is balanced by the extra lift Is posible descent the same distance from the same altitude and land at the same point with diferent angles? i dont see it. Within the first year of production, Champion began offering the Lycoming O-235-C1 engine of 115 horsepower (86kW) as an alternative to the Continental. It may not display this or other websites correctly. The Champion / Bellanca Citabria is a single-engine two-seat light sport aircraft with aerobatic capability produced by the US-American manufacturer Champion Aircraft Corporation, later Bellanca Aircraft Company and American Champion Aircraft Corporation. Glide ratio: 23-1 : Max G: Tow: American Champion Citabria 7GCAA Sn#:2 Tail #: N7519F Description: The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. All airplanes are designed to be able to glide to anticipate the worst case when the engine is failure. The real-world measurements I've done with our 182 resulted in a 7.04:1 glide ratio. This is great!! A glider improves its glide ratio relative to the earth by speeding up if there is a headwind, or a downdraft. IF IM WRONG SOMEBODY OUT THERE PLEASE SET ME STRAIGHT. . See the airplanes P.O.H. Thus, the only remaining variable left to change our lift is velocity (V), or airspeed. More Info. PN: 1-2550 Alt_PN: AN6-25. The 1979 book I have has performance charts, but my 2001 book doesn't. Go figure. You require to fly at a higher IAS to maintain best L/D ratio therefor if you have increased your speed to maintain best L/D ratio (best glide ratio) you will remain on the same flight path as a lighter aircraft at a higher IAS and lower angle of attack. I don't know of a list. The Kodiak is a true STOL (Short Take Off and Landing) aircraft powered up front by a PT6A-34 producing 750 shp allowing the Kodiak to get off the ground in just under 1,000 feet . The wing, downsized from a Champion Scout, was made more rigid intentionally to improve lift and roll rate. Wikipedia (https://en.wikipedia.org/wiki/Gliding_flight#Glide_ratio). Glide ratio measures the performance of an aircraft's glide; many modern gliders have a glide ratio better than 60:1. The engine was replaced with a Lycoming IO-320-E2A of 150 horsepower (110kW), while a header tank of 1.5 gallonslocated beneath the instrument panelwas added to the fuel system. When imported it was registered in the USA - as an A model. N7409Z SN#:25-3375, Copyright 2015-2023 Finger Lakes Soaring Club. Bellanca continued production of the 7GCBC, calling it the Citabria "C" Package (a designation apparently begun by Champion). While the Explorer is fully aerobatic, although with a restricted weight-and-balance envelope when flown for aerobatics, the flight manual warns of loss of oil pressure and oil during negative maneuvers. The only effect weight has is to vary the time the aircraft will glide for. When introduced, it featured wood-spar wings and oleo-shock main gear. Really ? What, if any, specialty instruments are used for professional glide ratio testing (such as a manufacturer developing a new model)? Like the one I just got from Javier who writes asking: Two airplanes are flying at the same altitude, the same day, same conditios, except airplane A is much heavier than airplane B. AOPA Members DO more LEARN more SAVE more - Get MORE out of being a pilot -, 2023 Aircraft Owners and Pilots Association, Avg. Weight opposes lift, it does not oppose drag. The glide ratio is based only on the relationship of the aerodynamic forces acting on the aircraft. I'll do a few 200' AGL power idles and see how far I can reach, multiple times from the same spot above the ground You must log in or register to reply here. How much does a Citabria cost? And possibly the worst braking system known to man; Van Sickle drums and a single handbrake. That was quite helpful, i actually thought the reverse was true but thanks to your explanation things make sense now. The Citabria is based on the Champion 7-series airframe. In addition, the carburetor was replaced with a fuel injection system, and a Christen Industries inverted oil system was fitted to the engine. Description: The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. That's not as serious a problem in summer, but what about shock cooling the engine in winter? A car that has alot of horsepower is 300+. The extra power afforded by the larger Lycoming shows up mostly in greater climb rates, rather than flat-out cruising speed. Instead of best glide SPEED, memorize best glide ATTITUDE. Lighter Total system is now 3 lbs. American Champion has been using aluminum spars in the aircraft it has produced and has made the aluminum-spar wings available for retrofit installation on older aircraft. Intended as a lower-priced competitor to the Piper Super Cub, Mehlhaff sees it as a utility aircraft, whether it be on floats or skis, and as a glider tug aircraft. So I'd guess best glide speed is 80-ish. The major differences between these two models are that the 7GCBC has a wingspan of 34.5 feet (10.5m), 1-foot (0.30m) longer than the 7ECA and 7GCAA, and carries wing flaps. the descent speed increases, but the glide ratio . Notice, there is no weight given here. American Champion Aircraft Corporation acquired the Decathlon design, along with the 8GCBC Scout and the group of Citabria and Champ variants, in 1990, bringing the Super Decathlon version back into production that same year. Which airplane will arrive first to the ground? The engine is a Lycoming Model O-235-K2C and is rated at 118 horsepower. So, there isn't better glide performance at altitude. Heres one from aerodynamics test: Silly me, so long as youre gliding anyone can carry unlimited weight and glide for miles! The airplane is powered by a horizontally opposed, four cylinder, direct drive, normally aspirated, air cooled, carburetor equipped engine. hotrod180 offline. Table of Contents. Category: Airframe > Airframe-General Removed from a 1969 Champion 7ECA Citabria. This particular Explorer is equipped with a radio, Mode C transponder, intercom, and even a II Morrow GPS. Cleveland - 062-00300 - Piston. The cross-section of the metal fuselage truss is triangular, a design feature which can be traced back to the earliest Aeronca C-2 design of the late 1920s. Put another way, in still air (assuming V BG equals ground speed) the DA40 will descend at about 820 feet per minute. Airplanes fly on excess power, not grace, not engineering. If the C-172 has an L/D of 9.5. American Champion expects to begin building the 7GCAA in a year, but with a 160-hp engine. 14:1 means 14 km of distance per 1 km of altitude. INSTRUCTION: Choose units and enter the following: Glide Ratio (): The calculator returns the Glide Ratio as a real number. The major difference was in the engine, which in the 7GCAA was a Lycoming O-320-A2B of 150 horsepower (110kW). the glide ratio is independent of the weight or mass of the aircraft. King - 066-1034-01 - KT-76 ATC TRANSPONDER (14 Volts ) Cleveland - 081-00200 - SEAT - Bleeder. Gliding Distance is given by. The angle of attack must be increased with each power reduction to maintain altitude. The Decathlon entered production at Champion in 1972, immediately before the company was acquired by Bellanca Aircraft Corporation, so only a handful were produced by Champion. N234WE, Tow: American ChampionCitabria 7GCAA Sn#:2Tail #: Posts: 9992. 1111, Glider: CentrairPegasus 101BTail #: The Citabria POH/AFM is a piece of junk, isn't it? Some will find it easier to use a different calculation. Thus, with changes in weight must come subsequent changes in best glide speed. for approved maneuvers in the acrobatic category. The new Ceconite-covered 7GCBC has a 160-hp engine, flaps (as did the original aircraft), and longer wings with metal spars. Introduced in 1964, the 7ECA was the first version of the design and utilized the Continental O-200-A engine of 100 horsepower (75 kW). Thats why planes have gross weight limits. (Use your L/D max speed). All of these changes were made in order to allow for extended inverted flight, a mode not possible in the earlier models. that specific attitude. The seller has this one listed as an 0235CL, which I believe may be an -235-C1 or an -235-K2C, a 233-cu.in. Fuel quantity is registered by two direct reading float type gauges, one for each tank. Tracking the runway centerline required little effort. THE ONLY CHANGE THAT OCCURS IS IT WILL GET THERE QUICKER. Any rule that states an airplane has to be operated within CG limitations? when I had my mac attack that is what I did and it seem to work.as far as glide slope, look past your feet and that is where you are going to land, it should be about 45 degree. Pretty impressive. Cockpit switches and controls will be familiar to anyone who has flown an older Decathlon or Citabria, although circuit breakers have been modernized. Most think this is blasphemy, so take it with a grain of salt: Variations in aircraft weight do not affect the glide angle . Views: 614 The Micro Citabria charger stand is identical to the Cessna. Merry Christmas everyone! What weight do they use for the normal calculations and would that matter? Champion 7ECA Citabria - 1 . Length: 22 9. 1973 & On, Bellanca Champion Citabria 7ECA, 7GCAA, 7GCBC & 7KCAB Service Manual Original . Compared to the Citabria's wingspan of 33.5 feet (10.2m), the Decathlon's wingspan is shorter, at 32 feet (9.8m). One of my favorite civilian birds of all time.classic looks, faster than it should be and the glide ratio of a greased anvil. Champion 7ECA Citabria - BUSHING. Chris Prev 1 2 3 FirstPrev 3 of 3 Go to page Go Any faster and parasite drag increases and any slower induced drag will increase.. Champion and Bellanca built the Decathlon with several Lycoming IO-320 engine variants, all of 150 horsepower (110kW), and with the choice of a fixed-pitch or constant speed propeller. The glide ratio is based only on the relationship of the aerodynamic forces acting on the aircraft. A "High Country Explorer" version, with a Superior Vantage O-360-A3A2 engine of 180 horsepower (130kW) and larger wheels, is also produced by American Champion. Ours had all spraying equipment removed. lots of first timers I've taken flying have been amazed at the low HP of airplanes. A Cessna 172 might glide at 8:1, so it could go 8000 feet forward for each 1000 feet it lost at a Vg of 65 knots indicated (KIAS). 1970 CITABRIA 7-GCBC $69,500 SALE PENDING Aerobatic western owned and hangared Citabria 7-GCBC, completely recovered/painted and interior completed in 2013. Perhaps I am to understand that angle of attack stays the same in best glide, The major improvement in Bellanca's introduction of the Super Decathlon was the change of engine to the Lycoming AEIO-360-H1A or H1B, both of 180 horsepower (130kW), which was accompanied by a selection of constant speed propellers. The pilot suffered a catastrophic engine failure (cylinder separation) in a Cessna 205. Do it again for different airspeeds. I fly over a huge area of good LZ's. $145.00/hr. 5. The literature refers to a specific angle of attack, for best glide but how does one know the exact angle of attack, really ? Recommended Engine TBO: 2000 hours. Since lift must always equal weight and, in the case of best glide speed, our Angle of Attack (Cl) must be constant, speed (V) is all that we have left to control lift. To facilitate negative-g flight, the fuel system incorporates a 1.5 gallon header tank beneath the instrument panel, and the engine is fitted with a Christen Industries inverted oil system. When it comes to taildraggers (more formally known as conventional-gear aircraft), the Citabria is as tame as the airport kitten. How to stop ignition interference on radio. It is found by multiplying the weight by the sine of the glide angle. Pilots wanted an aircraft capable of more maneuvers, and Champion introduced the 8KCAB Decathlon in response to this demand. The Citabria designs passed through the hands of a number of companies through the 1980s, including a Champion Aircraft Company which was no relation to the Champion Aircraft of the 1960s. (35 gal. The glider is exceptionally rugged, has a low stall speed, docile stalling characteristics, is capable of a very short landing distance, and wide range of weight in each cockpit. They were also found in utility roles as bush planesthanks to their short take off and landing (STOL) ability, agriculture, pipeline patrol, and as glider towplanes. Description: The G102 Astir is a single seat fibreglas 15m Standard Class sailplane with a retractable wheel, designed by and built by Grob Aircraft, with the first flight in December 1974. 2. Federal Aviation Administration. #20. N3822A, Glider: SchweizerSGS 2-33ATail #: The plane resists the new AOA because its trimmed for a specific AOA, which it is engineered to want to re-establish, maintain. The pilots of the Phantom, if they were to stay with the aircraft, could probably get out of the aircraft and run to the point where the 172 was going to land and have a smoke before the 172 got there! We purchased it from Doug Cline in 2019. 45 mph and 45degree nose down. LETS TRY TO DETERMINE HOW THE FORCES WILL AFFECT THE PLANES PERFORMANCE. Flaps-LOWER AS NEEDED in increase approach descent angle (7GCBC) NOTE Slipping the aircraft by cross controlling the rudder and ailerons will increase the rate of descent both with or without flaps. Prop stopped, which helped the glide ratio quite a bit. THE GLIDE RATIO (AND ITS GLIDE ANGLE) ARE UNCHANGED Said for years..every pilot should know his best glide, write it on your dash. The heavier? Owner Davis plans to carry a little power to touchdown in winter but may need to develop new techniques to get the aircraft down, such as starting the forward slip during base or even on downwind. When the Citabria was introduced, it was the only airplane being commercially produced in the United States which was certified for aerobatics. Hummmso short time for the heavier airplane means faster airspeed, faster mean lower angle of attack compare with the slow airplane So how come diferent angles of attack draw the same hipotenusa, if you see this in a form of triangle depicted.? This airplane is certificated in the normal and acrobatic categories. Bellanca introduced two designs with close connections to the Citabria: The 8KCAB Decathlon and the 8GCBC Scout.
