Like the original, it can handle a hefty 17-knot crosswind. YOU GET THERE QUICKER. Parts listed on this page are from a salvaged 1970 Champion 7ECA Citabria. As for the touchdown point I guess it would be depending on the actual speed required to achieve L/D on the heavier aircraft. (just kidding). (35 gal. Champion's first Citabria flew as a prototype in May 1964. N20737, Glider: HoltzMach 0.1 SimulatorTail #: Champion switched to spring steel main gear legs in 1967. Prop stopped, which helped the glide ratio quite a bit. 5. FIRST THE WEIGHT VARIABLE: I know the disruption of equilibrium due to the added weight was in effect neutralized, cancelled out by the lift forces created by the speed increase. The main gear legs of most Citabrias are made of spring steel, though American Champion began to use aluminum gear legs in 2004. One point did seem worrisome, however. 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. 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). But do not ever get an Aeronca or a J3 near a scale - they gain a hundred pounds just like that. PN: 1-2550 Alt_PN: AN6-25. It's not a fixed number and the 50:1 ratio will only be achieved at one speed. Wikipedia (https://en.wikipedia.org/wiki/Gliding_flight#Glide_ratio). The following formula is used: = S / H where: = Glide Ratio S = distance of forward travel 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. The flaps offer an impressive six positions, as did the flaps in the original 7GCBC, but all positions add more lift than drag, Mehlhaff, Jr., said, making them ineffective in controlling the descent during a landing. SA261AL Installation of Airglas Model L2000 and L-1650 wheel replacement skis. N574KS, Glider: GrobG 102 Astir CSTail #: American Champion's 7GCAA, reintroduced in 1997 as the Citabria "Adventure," is similar to earlier versions, with the exception of the metal-spar wings and the use of the Lycoming O-320-B2B engine of 160 horsepower (120kW); the most recent significant design change has been the switch to aluminum main gear legs in 2004. Said for years..every pilot should know his best glide, write it on your dash. . 91 or F.A.R 135. The only thing that has changed is the rate at which the plane is proceeding along the glide path. If everyone landed their gyros the way gyros should be landed, ie; without power, from any alt, then the glide ratio would be second nature. The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. Reduce power but maintain altitude, reduce power some more, maintain altitude. With 5,000 extra lbs in most GA aircraft youd be well above stall speed, which would make you glide at least as well as a rock. When imported it was registered in the USA - as an A model. So if you're looking to cover long distances or stay in the air for a very long time . It was substantially similar to the 7GCAA of the same year, with wood-spar wings and spring steel main gear legs. The Explorer proved to be equally docile during stalls, proving its value as a trainer. Dec 19 2022. One of these aircraft is displayed at the Rahmi M Ko Museum in Istanbul. Because the AOA remained unchanged, this once again perfectly balanced plane will remain on its same glidepath and arrive at the same touchdown point. Range: 500 miles. A C172 w 9.5/1 glide ratio (L/D) has a 6.01 deg. Obstacle: 850 ft. VNO(Maximum Structural Cruising): 120mph. Daher Kodiak 100 Specifications. This frees you to make the decisions and troubleshoot. Glide ratio usually varies little with vehicle load; a heavier vehicle glides faster, but nearly maintains its glide ratio. We use cookies to help you get the best experience when using our website. TO OUR GLIDE TIME? . BUT ONLY IF THE PLANE WAS DESIGNED WITH WINGS TO SUPPORT SUCH A LOAD. 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. 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. 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 . Instead of best glide SPEED, memorize best glide ATTITUDE. 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. 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. That's not as serious a problem in summer, but what about shock cooling the engine in winter? Federal Aviation Administration. [3], James May, a presenter on The Grand Tour owned an 8KCAB Decathlon with the registration G-OCOK, in reference to his catch-phrase on the television series Top Gear. If you wish to make some sort of pursuasive argument then post up some horrid examples of glide ratios for twins. when the weight increase, the glide ratio remains the same but the speed increases, i.e. Maule Air Texas Inc. OR USA (214) 384-1858 . Custom Doggy Mat. Like the 7KCAB, the engine of the 8KCAB has a fuel injection system, as opposed to a carburetor. 1974 AMERICAN CHAMPION 7-KCAB CITABRIA New Item. fitness for any purpose is made or implied. Rolls are okay, though and loops. Aircraft: Citabria N990WY. Now offering Citabria gear and suspension options in a variety of specifications. D) be indeterminable. I also know there is a direct relationship between AOA and airspeed. So tell me (Jim and Paul) what is the AoA for my Citabria or C172 ? Sign in The Decathlon design 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, but no Decathlons were built in that period. This glider was rebuilt by Chuck Zabinski and Jake Smith. This should be a indicated airspeed you should try and maintain the second your engine quits or starts sputtering. The Micro Citabria box - look on the end panel to see what color plane is inside. BUT by the manufacturer or FAA. Weight opposes lift, it does not oppose drag. AN6-25 BOLT 1-2550 BUSHING AN310-6 NUT AN945-6P WASHER. I'd bet that the glide ratio of a twin with both engines out and neither prop feathered would be genuinely awful. 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. Bill Piper really needed to have someone shot over that! Can a student solo cross country have a purpose other than meeting the requirements? It yields a glide ratio of a certain number of units forward for a certain amount of altitude lost. Perversely, adding weight means that the best glide angle occurs at a faster speed. Well I stuck my neck out on this one. (The Citabria was certified under older CAR 4a regulations, when a more extensive flight manual was not required.) Keep in mind, though, you're going quite a bit slower than your best glide speed, and that can significantly impact your glide range. Both aircraft will cover the same distance but the lighter one will take a longer time to do so. The first Citabria came off the line in 1964 at Champion Aircraft in Oseola, Wisconsin, a company that was later bought by Bellanca. 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. 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. The Decathlon entered production in the United States in 1970 as a more powerful and stronger complement to the American Champion Citabria line of aircraft. They're located in Rochester, Wisconsin (262-534-6315), or on the web at www.amerchampionaircraft.com. This could possibly be the OLDEST thread every resurrected! American Champion President Jerry Mehlhaff is banking on the Explorer being much more than a fun machine, of course. 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. The Decathlon traces its lineage back to the Aeronca Champ, by way of the Citabria. http://www.skybrary.aero/index.php/Glide_Performance. JavaScript is disabled. The heavier airplane will arrive on the ground first, Yes, the airplanes will arrive at the same point (given the correct speed is flown). A-759. Ever wonder how far you could glide given a certain altitude? Like the Citabria, the Decathlon features tandem seating and center-stick controls. How would you go about finding it yourself? Official Burn Certificates. 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. No answer. Champion introduced the 7GCBC in 1965. Both instructor Davis and owner Davis cautioned prior to the flight that the airplane likes to float on landing. This is important. Airplanes fly on excess power, not grace, not engineering. Per the C180 owner's manual, sea level best rate is listed as 87 - 90 mph. Tracking the runway centerline required little effort. Does the extra weight provide the extra energy to offset the extra drag? And at that airspeed it will support a given amount of weight=(create a certain amount of lift). Solo Date: November 19, 2022. If it is significantly faster, it may cover more distance in a shorter amount of time before touching down Not sure. Both at the same time? That model was abandoned by aerobatic enthusiasts in favor of the Champion Decathlon 8KCAB because of its better inverted flight performance. Vy in your airplane is 69 mph. Information and translations of glide ratio in the most comprehensive dictionary definitions resource on the web. Glide ratio is defined as the ratio between altitude when it start gliding (Y-axis) to the distance it can reach until the altitude reach zero (X-axis), as shown in the picture 2. What, if any, specialty instruments are used for professional glide ratio testing (such as a manufacturer developing a new model)? How much does a Citabria cost? The American Champion Super Decathlon uses the AEIO-360-H1B, along with a constant speed propeller. When introduced, it featured wood-spar wings and oleo-shock main gear. Mark, not exactly. A typical American training glider has a glide ratio of about 24:1. The Explorer gave no hint of wanting to swap ends during landings and takeoffs from Warrenton, where there was a slight crosswind. Table of Contents. You would have to have a different attitude (sight picture) to achieve this. For example, a 50:1 glider will fly 50m for every 1m it drops. 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. And it means you have more vertical speed to arrest in that latter phase. Sorry, JavaScript must be enabled.Change your browser options, then try again. The Citabria POH/AFM is a piece of junk, isn't it? The first quoted paragraph said; That is the lesson we learn about slow flight and stalls. Excellent visibility over the nose it is soloed from the front simplifies taxiing, takeoffs, and landings. The fuel tanks are vented together with the vent located on the left wing. 45 and 45 is what I was told. Merry Christmas everyone! The factory calls it a "Champ on steroids with flaps." Then add a metal prop or a starter and battery, and a wing tank . Glide ratio usually varies little with vehicle load; a heavier vehicle glides faster, but nearly maintains its glide ratio. I just read elsewhere that altitude / air density does not effect glide ratio but it seems your explanation says it does effect glide ratio. Most think this is blasphemy, so take it with a grain of salt: Takeoff Distance Over 50-ft Obstacle: 895 ft. I don't know of a list. If the weight is reduced and the IAS held constant, the glide angle will: Fuel Burn at 75% power in standard conditions per hour. 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. Gliding is a descending, opposite of climbing, which is ascending. LETS SEE IF WE CAN CORRECTLY FIGURE OUT THE ANSWER! Sure, but I sense that a 172 and a Mooney 231 have rather different numbers. The Glide Ratio is the ratio of distance forward to distance downwards when a glider is flown at a constant speed in still air. 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. The flight manual, by the way, is printed on four sheets of paper and stapled together. 2. N7519F, Tow: PiperPA-25-235 PawneeTail #: Our FLSC Pegasus is a B model that has a carbon fiber main spar, This is a question I was asked a few days ago, and I cant find the correct answer. Revision 67. Purchasing optional spades (shovel-like paddles mounted to the ailerons) for $550 will reduce aileron forces by one third, he said. 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). Aircraft Owners & Pilots Association Find it free on the store. There is a forward component of weight (relative to Drag) that moves the aircraft forward. 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. Bellanca Citabria 7GCBC. Especially when the angle is so slight. A wide panel holds all the latest avionics we're in 1968, so that includes a . 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 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 model 7ECA Citabria entered production at Champion in 1964. The extra energy from the weight does nothing to the drag. Is all that possible ? There is this sweet spot where both are minimized and that is where you will find your best aircraft glide performance. (Probably similar to the "pregnant brick" mentioned earlier.). 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 . Heres one from aerodynamics test: A) decrease THE ONLY THING WEIGHT DOES IS BRING THE PLANE DOWN THE GLIDE PATH AT A FASTER RATE. Login required to see more detailed info on each aircraft. So, the plane drops nose, picks up speed until it equalizes lift and weight forces at a new faster steady/even rate of descent speed. Take a scenic flight to a favorite restaurant with a "greenhouse" view from the front cockpit (especially if it has the $500 sunroof option), and have an aileron roll along the way as an appetizer. The literature refers to a specific angle of attack, for best glide but how does one know the exact angle of attack, really ? A 5 deg angle (glide path) gets you 1909 feet farther while Come on Paul. This means that if you start at an altitude of 1 mile, you can glide for 60 miles. Bellanca continued production of the Decathlon throughout the 1970s, moving to the Super Decathlon variant during 1976. A typical commercial airliner will glide at a ratio of about 3:1. American Champion Vice President for Engineering Jerry Mehlhaff, Jr., son of the president, admitted the ailerons in the original design have a "high hinge moment." Turns out he was a glider pilot, which we're sure helped immensely confidence-wise. This Bellanca Citabria is ready for an afternoon of fun! Nationality and Registration MarksZK-CIT. The outer shape of the fuselage is created by a combination of wooden formers and longerons, covered with fabric. The last two positions, 27 degrees and 35 degrees, are a tough pull. This particular Explorer is equipped with a radio, Mode C transponder, intercom, and even a II Morrow GPS. Useful Load: 550 lbs. The winds would have to be factored in as well. Do you disagree? So what does all this gibberish mean, right? 4. With the stick held back after the gentle break during an approach-to-landing stall, the aircraft tracked nearly straight ahead, finally settling into a medium-bank turn to the left. And how do I judge that angle ? Welcome Guest. should i maintain the same speed or should i increase my airspeed by increasing dive angle to get 1000 ft .min ROD. The real-world measurements I've done with our 182 resulted in a 7.04:1 glide ratio. Usable) Oil Capacity: 8 quarts Baggage Capacity: 100 lbs. Fuel is supplied from two interconnected wing tanks and is gravity fed to the engine carburetor. Would it be the same as your best climb? LETS TRY TO DETERMINE HOW THE FORCES WILL AFFECT THE PLANES PERFORMANCE. 2023 GlobalAir.com. Ours was built in 1984 and purchased from the Wings of Eagles Museum. To take advantage of the new light-sport aircraft category, the Champion was returned to production in 2007. tan(glide angle)=alt/distance. (if I could put a figure in here I would draw out the vector relationship). Someone on the internet gave a Vbg of 135MPH for a total glide time of 60 * (6/135) = 2 minutes 40 . It offers the added advantage of increasing wing strength. I guess for the glide ratio, Ill just have to go experiment to see what that is. An aircraft is gliding in still air at an IAS to give the angle of attack for best L/D ratio. What does glide ratio mean? Though variants of the design, and other better-suited designs have largely taken over the Citabria's utility roles, Citabrias remain popular as trainers, glider towplanes, and for personal use. Holy Smokes thats a good question! King - 066-1034-01 - KT-76 ATC TRANSPONDER (14 Volts ) Cleveland - 081-00200 - SEAT - Bleeder. flyingcheesehead, Dec 21, 2011. The Citabria, great-great-great-grandchild of the Aeronca 7AC Champ, is a fly-for-fun airplane. Bellanca continued production of the 7GCAA as the Citabria "A" Package (a designation apparently begun by Champion), but with no significant design changes. Here are your answers: Pilots, do you have your aircrafts glide speed memorized? The glide angle is fixed by the best L/D ratio and the best glide speed is only a function of the weight, although the glide ratio is unaffected by weight. The math looks like this: 1.5 nm * 6076.12 ft = 9114.18 ft. Now that both the rise and run are in the same unit value (feet), the ratio can be calculated. The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. It is also certified for aerobatic flight. Designed for flight training, utility, and personal use, it is capable of sustaining aerobatic stresses from +5g to -2 g. Its name, "airbatic" spelled backward, reflects . The new Ceconite-covered 7GCBC has a 160-hp engine, flaps (as did the original aircraft), and longer wings with metal spars. A little extra airspeed has minimal effect, but a little too slow is bad. Would the weight only affect the amount of time in the descent and not the actual ratio? 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. No Oil Required An aircraft has a single best glide speed for a given configuration. Decathlons and Super Decathlons remain popular as aerobatic trainers, as beginning and intermediate aerobatic aircraft, and as personal aircraft. Cleveland - 062-00300 - Piston. Thanks, hi i just wanted to ask that while practicing a flameout landing.. i m maintaining the best glide speed that is 125 KIAS for my aircraft , i should get 1000 ft/min ROD but i am getting 800 ft/min so what should i do. 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. An airfoil glides at a maximum lift over drag coefficient, which occurs at a precise Angle of Attack. American Champion Aircraft Corporation acquired the Citabria, Decathlon, and Scout designs in 1989 and returned the 7ECA, 7GCAA, and 7GCBC models to production over a period of years. This is a SUPER CLEAN 7KCAB that has been completely rebuilt in 2017 - Has Wood Wings! But a lovely bird. Since its reintroduction, the Super Decathlon has sold steadily. 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. CITABRIA EXPLORER 7GCBC. ** Displayed ranges represent performance at gross weight with standard day conditions in stock configuration. while the glide angle can change but glide ratio will stay the same. Glider: SchleicherASK 21Tail #: The only effect weight has is to vary the time the aircraft will glide for. It is still being produced. Bellanca introduced two designs with close connections to the Citabria: The 8KCAB Decathlon and the 8GCBC Scout. In comparison, a Boeing 747 has a 15:1 glide ratio. "It reduces a lot of problems," Mehlhaff, Jr., said. Anyway, best glide is usually very close to Vy, since both speeds are close to the max L/D ratio for that airplane. Ceiling: 17,000. The aircraft was powered by a 200hp (150kW) Lycoming IO-360 Special engine driving a two-bladed propeller. Note as you have increased your IAS (v2) a subsequent decrease in your Angle of attack (cL) is required. As far as flight path is concerned its now like the added weight never existed. 1.
