One of the major developments of the 8KCAB Decathlon over the 7KCAB Citabria is the Decathlon's wing, which employs a semi-symmetrical airfoil, as opposed to the Citabria's flat-bottomed airfoil. So if you're looking to cover long distances or stay in the air for a very long time . This airplane is certificated in the normal and acrobatic categories. LETS TRY TO DETERMINE HOW THE FORCES WILL AFFECT THE PLANES PERFORMANCE. Takeoff Distance Over 50-ft Obstacle: 895 ft. Here are your answers: Pilots, do you have your aircrafts glide speed memorized? twins are probably in the same range for engine out L/D i.e. Champion 7ECA Citabria - 1 . 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. (if I could put a figure in here I would draw out the vector relationship). It uses the CONDOR Soaring Software Program and is the same simulator used at the USAF Academy. 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. Examples of how to use "glide ratio" in a sentence from the Cambridge Dictionary Labs Further practice would reduce the landing distance still further. Interested in buying this aircraft click here. In 1970, Champion was acquired by Bellanca Aircraft Corporation, which continued production of all of the Champion-designed variants. Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from +5g to -2g. You can see the image damage at the end of the video. The 7GCAA and 7GCBC variants, added in 1965, were joined by the 7KCAB in 1968. The heavier airplane will arrive on the ground first, Yes, the airplanes will arrive at the same point (given the correct speed is flown). 14:1 means 14 km of distance per 1 km of altitude. TO OUR GLIDE TIME? The wings of Champion and Bellanca Decathlons were built with wooden spars. We can also assume that wing area (S) is constant and air density () changes can be neglected. 2023 Ask a Flight Instructor All right reserved. Youre right, flying the correct attitude is a much better approach to flying the aircraft during emergencies than trying to focus on maintaining a specific indicated airspeed. Tracking the runway centerline required little effort. The engine is a Lycoming Model O-235-K2C and is rated at 118 horsepower. Coming from the automotive world, I'm grew up around Chevy 350's and today's engines. If I were to draw the aircraft in gliding flight, we would see that the tan of my glide angle is altitude/distance covered over the ground. D) be indeterminable. . Drag is apposed by thrust. Weight opposes lift, it does not oppose drag. a 7 deg angle (glide path) gets you 1366 feet less ~ Or is the extra drag just neglected in the calculation? So what does all this gibberish mean, right? The real-world measurements I've done with our 182 resulted in a 7.04:1 glide ratio. An orificed one-way check valve allows a minimum of fuel to be vented overboard during negative G aerobatic maneuvers. 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. 2. The airspeed and angle of attack are related directly, yes ? Every once in a while I get a question on askacfi.com that Im pretty sure is a homework question but I still dont mind answering it. Useful Load: 550 lbs. The angle to the left wing from the pilot eyes is around 5.4 degrees. Empty Weight: 1200 lbs. Champion 7ECA Citabria - 1-2280 - CABLE ASSEMBLY - RUDDER PEDAL. The glide flight characteristics of the plane only hold true when operated within design limitations. Boldmethod. It was substantially similar to the 7GCAA of the same year, with wood-spar wings and spring steel main gear legs. Notice, there is no weight given here. Aircraft There is a forward component of weight (relative to Drag) that moves the aircraft forward. The Citabria traces its lineage back to the Champ. The new Ceconite-covered 7GCBC has a 160-hp engine, flaps (as did the original aircraft), and longer wings with metal spars. Cruise speed: 126 mph. Table of Contents. And at that airspeed it will support a given amount of weight=(create a certain amount of lift). The Glide Ratio calculator computes the glide ratio based on the change in forward distance and the change in altitude. In that period, only one Citabria model was builta 7GCBC marketed as "Citabria 150S." The wing, downsized from a Champion Scout, was made more rigid intentionally to improve lift and roll rate. I do engine off landing all the time.. The Citabria POH/AFM is a piece of junk, isn't it? The 7GCAA was basically the same as the 7ECA, but with a 150-hp engine. air . To emphasize a glider term, sink rate matters. Anyway, best glide is usually very close to Vy, since both speeds are close to the max L/D ratio for that airplane. Bellanca continued production of the 7GCAA as the Citabria "A" Package (a designation apparently begun by Champion), but with no significant design changes. 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). 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. Then add a metal prop or a starter and battery, and a wing tank . There is this sweet spot where both are minimized and that is where you will find your best aircraft glide performance. On the aircraft I fly, the 744, at high gross weights, the ratio approaches almost 4:1, the aircraft doesn't want to come down at all. Because the AOA remained unchanged, this once again perfectly balanced plane will remain on its same glidepath and arrive at the same touchdown point. Champion 7ECA Citabria - . Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from +5g to -2 g. Its name spelled backwards, "airbatic", reflects this. 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. Ceiling: 17,000. Champion switched to spring steel main gear legs in 1967. This glider was rebuilt by Chuck Zabinski and Jake Smith. 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! A) decrease $85,500 Reg# N8552V TT: 2408; Performance Specs. Probably displaying my lack of understanding. A lot of misinformation going on here. Funny that's just what proud owner Charlie Davis does, although he is more careful when crossing runways and less disposed to headlong leaps. Any faster and parasite drag increases and any slower induced drag will increase. N3822A, Glider: SchweizerSGS 2-33ATail #: C) remain the same SPECIFICATIONS. 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. A 1.7 NM per 1000 feet glide is an angle of 5.5 degrees, Arc-Tan (1000/ (1.7*6076)) = 5.5 degrees. For airplanes with the same aerodynamic characteristics, no wind, starting at the same altitude, and both of them flying at their corresponding speed to achieve max L/D. Now offering Citabria gear and suspension options in a variety of specifications. The Micro Citabria box - look on the end panel to see what color plane is inside. 3, 2005.) YOU GET THERE QUICKER. Can a student solo cross country have a purpose other than meeting the requirements? The last two positions, 27 degrees and 35 degrees, are a tough pull. Your Cessna needs 120HP (75%) to maintain it's rated cruise speed. Ours was built in 1984 and purchased from the Wings of Eagles Museum. Login . This is great!! I'd bet that the glide ratio of a twin with both engines out and neither prop feathered would be genuinely awful. 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). Decathlons and Super Decathlons remain popular as aerobatic trainers, as beginning and intermediate aerobatic aircraft, and as personal aircraft. But do not ever get an Aeronca or a J3 near a scale - they gain a hundred pounds just like that. The Explorer likes to fly. I don't know of a list. The only effect weight has is to vary the time the aircraft will glide for. The electrical system is 12 volts, direct current, using the airframe as a negative ground. Would it be the same as your best climb? The fuel tanks are vented together with the vent located on the left wing. tan(glide angle)=alt/distance. Both aircraft will cover the same distance but the lighter one will take a longer time to do so. So Joe, Jim and Paul are correct but they have not told us how they determine Well I stuck my neck out on this one. Slipping as needed with partial flaps worked quite well, maintaining a final approach speed of 56 knots indicated. The winds would have to be factored in as well. N574KS, Glider: GrobG 102 Astir CSTail #: Operating them while strapped into a parachute and with the front cockpit's five-point harness hooked requires more than a few grunts. Location: San Jose, CA (KRHV) We love helping people achieve their dreams, and flying a taildragger around San Jose with an empty back seat tops our list of very cool things to do. Further improvements to the 7GCBC include use of the heftier front wing strut from a Decathlon, which is attached to the wing with a beefed-up end fitting. 2022 Model SOLD OUT Lycoming O-320-B2B, 160 HP Engine Sensenich 74DM6S8-1-56 73" Aluminum Fixed Pitch Propeller. 45 mph and 45degree nose down. Fuel Capacity: 36 gal. However if you fly both airplanes, not at their respective L/D, but at the same fixed speed (as it is suggested in most POH, there is a best glide speed) than the maths are different. This Bellanca Citabria is ready for an afternoon of fun! Like the Champ, the Citabria features tandem seating. The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. Power Plant: Lycoming O-320-B2B. Aircraft weight, air density (e.g. NO OTHER CHANGES. Demonstrated Crosswind Component: 17kts. . JavaScript is disabled. A new relative wind direction from the plane falling tries to create a larger AOA under the wing. The major differences between the7GCAA and 7KCAB were in the fuel system and the engine oil system. This is a question I was asked a few days ago, and I cant find the correct answer. More speed equals more drag which translate into a higher sink ratewhich translate in loosing more altitude for the same amount of time unit The flight path and the AoA are 2 different things not to be confused. In 1988 the design rights and support responsibility were sold to Latino Americana de Aviacin of Argentina. When introduced, it featured wood-spar wings and oleo-shock main gear. The 7GCBA (ag spray plane) is certified to 2400lbs (I admit I know nothing about it's structure). The glide ratio is based only on the relationship of the aerodynamic forces acting on the aircraft. The weight is no longer a factor in this scenario. the glide ratio is independent of the weight or mass of the aircraft. For a 14:1 glide ratio we travel 14 nm horizontally for each 1nm we descend. Compared to the Citabria's wingspan of 33.5 feet (10.2m), the Decathlon's wingspan is shorter, at 32 feet (9.8m). With no other changes the plane starts too fall. And it means you have more vertical speed to arrest in that latter phase. When American Champion reintroduced the 7ECA in 1995 as the Citabria "Aurora, " the biggest change was the use of metal-spar wings; the most recent significant design change has been the switch to aluminum main gear legs in 2004. Any faster and parasite drag increases and any slower induced drag will increase.. The pilot suffered a catastrophic engine failure (cylinder separation) in a Cessna 205. 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. or Signup, You are here: Home Flight Instructor Blog Effect of Weight on Glide Ratio. Top of wing tip to top of cabin 2 feet. It's not a fixed number and the 50:1 ratio will only be achieved at one speed. Instructor: Scott Williams. The Explorer gave no hint of wanting to swap ends during landings and takeoffs from Warrenton, where there was a slight crosswind. 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. 7ECA, Citabria Standard, Citabria Aurora. If the weight is reduced and the IAS held constant, the glide angle will: Cockpit switches and controls will be familiar to anyone who has flown an older Decathlon or Citabria, although circuit breakers have been modernized. Propelle: Sensenich 74DM6S8-1. https://en.wikipedia.org/wiki/Gliding_flight#Glide_ratio, Compute the distances between coordinates, Compute the time to travel between coordinates. 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. Is all that possible ? Discussion in 'Flight Following' started by Morne, Dec 21, 2011. average spam cans seem to be right around 8 or 9:1. it only depends on its shape, and mostly on the shape of the wings, e.g. Our FLSC Pegasus is a B model that has a carbon fiber main spar, So, there isn't better glide performance at altitude. Wow! 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. Congrats to Ian and CFI Scott for checking this box off his list. Aircraft specification no. It is still being produced. LETS SEE IF WE CAN CORRECTLY FIGURE OUT THE ANSWER! 15:1 from 2000 feet gives a distance of 30000 feet or about 6 miles. So if he creates a few wings sets (6 or 7) with the same surface and varying only the cord and span starting with low aspect moving onto high aspect and seeing which ones glide furthersomewhere in there he would find the "right" AR. Usable) Oil Capacity: 8 quarts Baggage Capacity: 100 lbs. You are using an out of date browser. glide path is not the same as attitude / angle of attack (AoA). This is before CAM8 increase. The Champion 7ECA Citabria was a modernized version of the Champion Model 7EC Traveler. How do you determine the best engine off glide ratio in a gyro? This speed is important as it represents the bottom of the drag curve. The similar, although more rugged, 8 series is used for the Scout bushplane and the more fully aerobatic Decathlon. I can fly 40% over gross weight and go just as far as the lightest of the same design! Views: 812 They also now manufacture the Citabria Adventure and the Citabria Explorer. Heres one from aerodynamics test: I do most every landing with engine idle, so I obviously know the drill. For example, a 50:1 glider will fly 50m for every 1m it drops. Is posible descent the same distance from the same altitude and land at the same point with diferent angles? i dont see it. In this example, the glide ratio provided in the POH comes out . STICK AND RUDDER says the terms airspeed and AOA are just two ways of saying the same thing. 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." Dec 19 2022. THE ONLY THING WEIGHT DOES IS BRING THE PLANE DOWN THE GLIDE PATH AT A FASTER RATE. Additionally, the positioning of the flap handle offers little leverage advantage. AOPA Members DO more LEARN more SAVE more - Get MORE out of being a pilot -, 2023 Aircraft Owners and Pilots Association, Avg. Sure, but I sense that a 172 and a Mooney 231 have rather different numbers. HOLY COW!! Aircraft: Citabria N990WY. The only thing that has changed is the rate at which the plane is proceeding along the glide path. (You must log in or sign up to reply here. In comparison, a Boeing 747 has a 15:1 glide ratio. The plane is now EXACTLY as buoyant as it was before. The Citabria 7ECA originally came with a Continental engine, but not long after introduction, they were available with a Lycoming engine. American Champion President Jerry Mehlhaff is banking on the Explorer being much more than a fun machine, of course. At a critical point angle of attack, the aircraft can maintain altitude only by increasing power and is said to be behind the power curve. 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. N20737, Glider: HoltzMach 0.1 SimulatorTail #: A high performance glider has a glide ratio of 60:1 (60 miles forward to ever y1 mile of altitude lost). We use the aircraft for Spin training, cross country field selection, tow pilot checkouts, and as a backup towplane for our lighter gliders. Thanks Jim. One of my favorite civilian birds of all time.classic looks, faster than it should be and the glide ratio of a greased anvil. Throttle - CLOSED when in gliding distance or runway 3. 1974 AMERICAN CHAMPION 7-KCAB CITABRIA New Item. (just kidding). Remember weight does affect stall speed. Compare. In other words, the Angle of Attack for best glide will not change. Airplanes fly on excess power, not grace, not engineering. Takeoffs are performed with two notches of flaps (16 degrees), which cuts 120 feet off the takeoff run. Perhaps I am to understand that angle of attack stays the same in best glide, But a lovely bird. Welcome Guest. Do it again for different airspeeds. I'll bet there are some out there. 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. Probably closer than you think. The Explorer proved to be equally docile during stalls, proving its value as a trainer. 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. Sign in The major difference was in the engine, which in the 7GCAA was a Lycoming O-320-A2B of 150 horsepower (110kW). Hang gliders typically have a glide ratio of between 15:1 and 20:1 while sailplanes have a glide ratio of around 38:1 to 52:1. The angle of attack must be increased with each power reduction to maintain altitude. The glide ratio varies with air speed, but there is a maximum value which is frequently quoted. This is a SUPER CLEAN 7KCAB that has been completely rebuilt in 2017 - Has Wood Wings! Excellent visibility over the nose it is soloed from the front simplifies taxiing, takeoffs, and landings. Most Citabrias were built with wooden spars. The Citabria POH/AFM is a piece of junk, isn't it? It is found by multiplying the weight by the sine of the glide angle. This describes me. Vy in your airplane is 69 mph. Not to mention a "what the heck, let's roll it airplane." hope this might help. No answer. Minimum sink is always slower than best glide, because it's the point on the power required curve where the least amount of power is required. The L/D ratio and the glide ratio are always equal in steady-state linear unpowered flight in still air, but they are not equal if there is some thrust from a motor. TO OUR GLIDE RATIO (AND ITS RESULTANT GLIDE SLOPE)? 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. The American Champion 8KCAB Decathlon and Super Decathlon are two-seat fixed conventional gear light airplanes designed for flight training and personal use and capable of sustaining aerobatic stresses between +6g and 5g. My [flying club's] M20J is about 13:1 a 172 is about 9:1. A-759. 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. (Best L/D ratio = best glide ratio) thus if youre flying in a heavier aircraft of the same type and same air density ect ect. It is our mission to be the go to leaders in the aviation industry. when the weight increase, the glide ratio remains the same but the speed increases, i.e. Citabrias were also popular as trainersbecause of their conventional gear and their aerobatic capabilitiesand as personal aircraft. 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 Citabria 7ECA can fly up to 11,500 feet and has a top speed of 104 knots, about 120 mph. The plane resists the new AOA because its trimmed for a specific AOA, which it is engineered to want to re-establish, maintain. People should practice engine-outs by landing with idle power whenever possible. Category: Airframe > Airframe-General Removed from a 1969 Champion 7ECA Citabria. The glide ratio is based only on the relationship of the aerodynamic forces acting on the aircraft. No Oil Required a pretty decent policy in airplanes is that if you can see it over the nose there is good odds you can't make it there. 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. Description: Our Club purchased this glider simulator in 2019 for our students from Russell Holtz. A sport pilot must pay at least half the operating expenses of the flight. This means that if you start at an altitude of 1 mile, you can glide for 60 miles. 8-10:1. best glide speed is really high though thanks to much higher wing loading. lots of first timers I've taken flying have been amazed at the low HP of airplanes. Introduced in 1964, the 7ECA was the first version of the design and utilized the Continental O-200-A engine of 100 horsepower (75kW). I would really appreciate if you could help me out. I would like to know the actual glide ratio of my airplane at several combinations of configuration and airspeed. Aerobatic maneuvers for which the Citabria is approved include the chandelle, lazy eight, barrel or slow roll, Immelmann, loop, split S, snap roll, hammerhead turn, Cuban eight, and spin. 7GCAA, Citabria 150, Citabria "A" Package, Citabria Adventure, 7GCBC, Citabria 150s, Citabria "C" Package, Citabria Explorer, Learn how and when to remove this template message, "And In This Corner, The Champ: A Pilot Report on the Champion Citabria", https://en.wikipedia.org/w/index.php?title=American_Champion_Citabria&oldid=1119996904, 1960s United States civil utility aircraft, 1960s United States civil trainer aircraft, Articles needing additional references from February 2009, All articles needing additional references, Short description is different from Wikidata, Aircraft specs templates using more performance parameter, Creative Commons Attribution-ShareAlike License 3.0. Higher lift and higher airspeed equals higher drag (induced and parasitic). Production at Bellanca ended in 1980 and the company's assets were liquidated in 1982. THE GLIDE TIME IS SHORTENED. Aircraft.com is the leading registry for planes, jets, and helicopters. 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. 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. Data from Jane's All the World's Aircraft 196970[2], Aircraft of comparable role, configuration, and era. 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. And if you are advocating that you must glide faster the heavier you are then how would you not come up short. It remains a widely used aircraft in agricultural spraying and is also used as a tow plane, or tug, for launching gliders or for towing banners. 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. A 5 deg angle (glide path) gets you 1909 feet farther while The Citabria was designed and initially produced by Champion Aircraft Corporation, and was a derivative of designs the company had been building since acquiring the 7-series Champ from Aeronca in 1954. This page was last edited on 4 November 2022, at 14:52. American Champion Citabria 7ECA Technical Specifications Exterior Exterior Height: 7 ft 7 in Wing Span: 33 ft 6 in Length: 22 ft 1 in Interior Cabin Height: 3 ft 11 In Cabin Width: 2 ft 6 In Cabin Length: 8 ft 10 In Occupancy Crew: 1 Passengers: 2 Operating Weights Max T/O Weight: 1750 Lb Empty Weight: 1120 Lb Fuel Capacity: 35 Lb 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. Ours had all spraying equipment removed. 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.
