citabria glide ratio

Length: 22 9. Official Burn Certificates. 13:1 with the prop stalled, MAYBE. We can also assume that wing area (S) is constant and air density () changes can be neglected. I fly over a huge area of good LZ's. Wow! Designed for flight training and personal use, it entered production in the United States in 1945. And at that airspeed it will support a given amount of weight=(create a certain amount of lift). If two aircraft have the same L/D ratio but different weights and start a glide from the same altitude, the heavier aircraft gliding at a higher airspeed will arrive at the same touchdown point in a shorter time. When the Citabria was introduced, it was the only airplane being commercially produced in the United States which was certified for aerobatics. The model 7ECA Citabria entered production at Champion in 1964. On this Wikipedia the language links are at the top of the page across from the article title. 1974 AMERICAN CHAMPION 7-KCAB CITABRIA New Item. Or how do you (avoiding mathematics) figure it out. A modern German counterpart about 33:1. ). JavaScript is disabled. The lighter? Bellanca 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: 1650 Lb Empty Weight: 1060 Lb Fuel Capacity: 35 gal Lb Payload Useful: 590 Lb (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. 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. The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. Production history [ edit] The electrical system is 12 volts, direct current, using the airframe as a negative ground. (Jun. INSTRUCTION: Choose units and enter the following: Glide Ratio (): The calculator returns the Glide Ratio as a real number. In addition, metal ribs were nailed to spars, but the nails would pull out. Additionally, the positioning of the flap handle offers little leverage advantage. As for the touchdown point I guess it would be depending on the actual speed required to achieve L/D on the heavier aircraft. 14:1 means 14 km of distance per 1 km of altitude. Now that I think of it, I could carry an extra 5,000 lbs. 4 products. Compared to the Citabria's wingspan of 33.5 feet (10.2m), the Decathlon's wingspan is shorter, at 32 feet (9.8m). Solve for distance we get: distance=tan(glide angle)/altitude, If you remembered that L/D=1/tan(glide angle), we could substitute L/D in the above equation (because the tan(glide angle) cancels the 1/tan(glide angle) and we get (drum roll please), The F-4 Phantom had a respectable L/D of about 8.7. Your glide ratio needs to be determined empirically. [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. 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. Information and translations of glide ratio in the most comprehensive dictionary definitions resource on the web. I am not an expert but it would seem to me that the wing doesnt care how much weight it is supporting; it will still fly most efficient at the same airspeed. The new Cessna 177 Cardinal with its cantilever, laminar-flow wing offering terrific visibility is a doll to fly, a step above its trusty-yet-pedestrian predecessor. ? Ceiling: 17,000. Probably closer than you think. Overall, the aircraft delivers what it promises: fun. Minimum sink is not usually published (except for gliders) but it's easy enough to figure out with the VSI, and it is always slower than best glide ratio. Older Citabria 7GCBC aircraft produced in the 1960s and 1970s had wood spars that are prone to cracking. "It reduces a lot of problems," Mehlhaff, Jr., said. http://www.skybrary.aero/index.php/Glide_Performance. For a 172, there is a significant difference between powered L/D vs gliding L/D due to the additional drag of a non-powered rotating propeller. Its name spelled backwards, "airbatic", reflects this. Your Cessna needs 120HP (75%) to maintain it's rated cruise speed. [2] He took off from an airstrip at William Barron Hilton's Flying-M Ranch, about 70 miles (110km) southeast of Reno, Nevada. 32032 Washington Ave. Burlington, WI United States 53105. In comparison, a Boeing 747 has a 15:1 glide ratio. Aircraft The literature refers to a specific angle of attack, for best glide but how does one know the exact angle of attack, really ? The strut-braced wings of the Citabria are, like the fuselage and tail surfaces, fabric covered, utilizing aluminum ribs. This Bellanca Citabria is ready for an afternoon of fun! Notice, there is no weight given here. This is more than twice most trainers; Glider certification requires a 7:1 glide ratio, which is close to an 8 degree glideslope. 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. 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. CITABRIA EXPLORER 7GCBC. The winds would have to be factored in as well. Bellanca continued production of the 7KCAB as the Citabria "B" Package (a designation apparently begun by Champion). 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. Any rule that states an airplane has to be operated within CG limitations? Bellanca Citabria 7GCBC. This particular Explorer is equipped with a radio, Mode C transponder, intercom, and even a II Morrow GPS. I also know there is a direct relationship between AOA and airspeed. Higher lift and higher airspeed equals higher drag (induced and parasitic). 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. Bellanca continued production of the 7GCBC, calling it the Citabria "C" Package (a designation apparently begun by Champion). Citabrias were also popular as trainersbecause of their conventional gear and their aerobatic capabilitiesand as personal aircraft. the glide ratio is independent of the weight or mass of the aircraft. altitude) have no effect on the glide ratio. The 7GCAA and 7GCBC variants, added in 1965, were joined by the 7KCAB in 1968. Recommended Engine TBO: 2000 hours. Heres one from aerodynamics test: An aircraft is gliding in still air at an IAS to give the angle of attack for best L/D ratio. In other words, the Angle of Attack for best glide will not change. In 1967, Champion switched to spring steel main gear legs; by then, the Lycoming engine had become the standard. The main gear legs of most Citabrias are made of spring steel, though American Champion began to use aluminum gear legs in 2004. American Champion expects to begin building the 7GCAA in a year, but with a 160-hp engine. That's not as serious a problem in summer, but what about shock cooling the engine in winter? Fuel quantity is registered by two direct reading float type gauges, one for each tank. The wings of Champion and Bellanca Decathlons were built with wooden spars. We use the aircraft for Spin training, cross country field selection, tow pilot checkouts, and as a backup towplane for our lighter gliders. Higher is better. TO OUR GLIDE RATIO (AND ITS RESULTANT GLIDE SLOPE)? Instructor Davis said the aircraft requires a long, flat approach, but that was inhibited somewhat at Warrenton by trees off the approach end. Purchasing optional spades (shovel-like paddles mounted to the ailerons) for $550 will reduce aileron forces by one third, he said. N234WE, Tow: American ChampionCitabria 7GCAA Sn#:2Tail #: The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. RV General Discussion/News The main gear legs of most Decathlons are made of spring steel, though American Champion began to use aluminum gear legs in 2004. Not airspeed Joe, Angle of Attack. Top of wing tip to top of cabin 2 feet. 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. 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 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 was designed by the Champion Aircraft Corporation, and is a derivative of the 7-series Citabrias. Views: 614 The Micro Citabria charger stand is identical to the Cessna. Is posible descent the same distance from the same altitude and land at the same point with diferent angles? i dont see it. Best angle is listed as 70. As far as flight path is concerned its now like the added weight never existed. Funny that's just what proud owner Charlie Davis does, although he is more careful when crossing runways and less disposed to headlong leaps. 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. Due to its light weight, it climbs well, stalls benignly, will land in an incredibly short distance (due to the nose skid), and is an excellent glider for transitioning after solo and first cross country attempts. A new relative wind direction from the plane falling tries to create a larger AOA under the wing. Champion's first Citabria flew as a prototype in May 1964. An extremely expensive, highly competitive glider today can have a 60:1 glide ratio. 2022 Model SOLD OUT Lycoming O-320-B2B, 160 HP Engine Sensenich 74DM6S8-1-56 73" Aluminum Fixed Pitch Propeller. Higher lift requires higher airspeed for same AOA. Maule Air Texas Inc. OR USA (214) 384-1858 . should i maintain the same speed or should i increase my airspeed by increasing dive angle to get 1000 ft .min ROD. Variations in aircraft weight do not affect the glide angle . Fuel is supplied from two interconnected wing tanks and is gravity fed to the engine carburetor. Fuel Capacity: 36 gal. When imported it was registered in the USA - as an A model. Wing aspect ratio: 6.72; Length overall: 22 ft 8 in (6.91 m) Height overall: 7 ft 0 in (2.13 . 8-10:1. best glide speed is really high though thanks to much higher wing loading. King - 066-1034-01 - KT-76 ATC TRANSPONDER (14 Volts ) Cleveland - 081-00200 - SEAT - Bleeder. The most noticeable external changes to the design are the Citabria's squared-off rudder surface, wingtips, and rear windows. The only effect weight has is to vary the time the aircraft will glide for. 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 Boldmethod. Aircraft weight, air density (e.g. Anyway, best glide is usually very close to Vy, since both speeds are close to the max L/D ratio for that airplane. ? The aircraft was powered by a 200hp (150kW) Lycoming IO-360 Special engine driving a two-bladed propeller. A little extra airspeed has minimal effect, but a little too slow is bad. What else should I plan for, in checking this? . The trim control, same as that used on earlier Citabrias and Decathlons, is a sliding knob, much like the throttle, that is fast and simple to operate. Do it again for different airspeeds. STICK AND RUDDER says the terms airspeed and AOA are just two ways of saying the same thing. Landing Distance over 50-ft. . Obstacle: 850 ft. VNO(Maximum Structural Cruising): 120mph. 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. An ILS approach, with a 3 degree glideslope requires an 18:1 glide ratio. All rights reserved. Cruise speed: 126 mph. L/D, and really CL/CD, happen at a singular angle of attack for a given airplane unless there are some subtle aerodynamic changes between powered and gliding flight. THE GLIDE RATIO (AND ITS GLIDE ANGLE) ARE UNCHANGED This means that if you start at an altitude of 1 mile, you can glide for 60 miles. Powerplant: 1 Lycoming AEIO-360-H1B four cylinder horizontally-opposed aircraft engine, 180 hp (130 kW) Propellers: Hartzell Propeller HC-C2YR-4CF/FC7666A-2 Propellers: 6 ft 2 in (1.88 m) diameter Performance Maximum speed: 155 mph (249 km/h, 135 kn) at sea level Cruise speed: 141 mph (227 km/h, 123 kn) And since some Citabrias are indeed old airplanes, there are a few things to watch for when looking for one to bring home, most notably the wooden wing spars found in pre . Maximum speed: 162 mph. So I'd guess best glide speed is 80-ish. Just as when you are under power. Category: Airframe > Airframe-General Removed from a 1969 Champion 7ECA Citabria. The 7GCAA . Takeoff Distance Over 50-ft Obstacle: 895 ft. Champion 7ECA Citabria - 1 . THE GLIDE TIME IS SHORTENED. One glide I did from 7500' down to the surface at ~800 MSL resulted in an 11.54 glide ratio. Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from +5g to -2g. for approved maneuvers in the acrobatic category. On acquiring the design, Bellanca gave this model the name Citabria "Standard" and began using the 115 horsepower (86kW) Lycoming O-235-K2C engine. Airplanes fly on excess power, not grace, not engineering. Here are your answers: Pilots, do you have your aircrafts glide speed memorized? This page was last edited on 4 November 2022, at 14:52. This just doesnt seem to jive. People should practice engine-outs by landing with idle power whenever possible. Really ? An orificed one-way check valve allows a minimum of fuel to be vented overboard during negative G aerobatic maneuvers. Champion 7ECA Citabria - . View photos, ownership, registration history, and more. Then add a metal prop or a starter and battery, and a wing tank . There is a forward component of weight (relative to Drag) that moves the aircraft forward. Glide ratio measures the performance of an aircraft's glide; many modern gliders have a glide ratio better than 60:1. No one expects an air cooled 160hp with a carb. 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. (if I could put a figure in here I would draw out the vector relationship). 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. The heavier the aircraft is, the higher the airspeed must be to obtain the same glide ratio. Instructor: Scott Williams. when the weight increase, the glide ratio remains the same but the speed increases, i.e. glide path. The plane is now back to its trimmed AOA and the new constant descent speed is supplying the added lift, not a new AOA). Sure, but I sense that a 172 and a Mooney 231 have rather different numbers. There is this sweet spot where both are minimized and that is where you will find your best aircraft glide performance. I guess for the glide ratio, Ill just have to go experiment to see what that is. Discussion in 'Flight Following' started by Morne, Dec 21, 2011. average spam cans seem to be right around 8 or 9:1. But I think I found your answer from: This airplane is certificated in the normal and acrobatic categories. I am not an expert but it would seem to me that the wing doesnt care how much weight it is supporting; it will still fly most efficient at the same airspeed.. Reduce power but maintain altitude, reduce power some more, maintain altitude. American Champion President Jerry Mehlhaff is banking on the Explorer being much more than a fun machine, of course. Cruise Speed/Endurance with45 MinReserve @ 75% Power: 127mph/ 2.8 hrs, Fuel Consumption(55% to 75% Power, per Lycoming Data): 7.3 to 10gph. Best glide ratio is the most optimal - the highest - one. Increased wing rigidity is to blame for the float, Mehlhaff, Jr., said. Since it is the lift over drag (L/D) ratio that determines the gliding range, weight will not affect it. 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. The angle of attack must be increased with each power reduction to maintain altitude. 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. Im yet to see a gyro with a better G R than a rock. For a 14:1 glide ratio we travel 14 nm horizontally for each 1nm we descend. Login . 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. And how do I judge that angle ? It has a claimed maximum L/D = 41. In 1970, Champion was acquired by Bellanca Aircraft Corporation, which continued production of all of the Champion-designed variants. 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). All bets are off when the wing stalls. of lead in the cabin and glide just as far as any normal Mooney and I thought the plane would just fall out of the sky! Arrow is famous for a safe glide ratio - glides like a safe. Ever wonder how far you could glide given a certain altitude? 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. [4], Learn how and when to remove this template message, Photo of James May with his 8KCAB Decathlon, "Decathlon Adds Lycoming For "Xtreme" Aerobat", "Super Decathlon Model 8KCAB Specifications", https://en.wikipedia.org/w/index.php?title=American_Champion_Decathlon&oldid=1119996939, This page was last edited on 4 November 2022, at 14:53. 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). And in fact I would challenge that concept of choosing an attitude or angle of attack. The first quoted paragraph said; This speed is important as it represents the bottom of the drag curve. 5. Cars only need 20-40 HP to maintain highway speeds. What does glide ratio mean? Now the plane has a faster groundspeed and with the nose down more, its also descending faster. Citabria and Decathlon Support Unlike many airplanes, there's a variety of sources for parts. 45 and 45 is what I was told. Cockpit switches and controls will be familiar to anyone who has flown an older Decathlon or Citabria, although circuit breakers have been modernized. Glide ratio usually varies little with vehicle load; a heavier vehicle glides faster, but nearly maintains its glide ratio. 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. 45 mph and 45degree nose down. If you wish to make some sort of pursuasive argument then post up some horrid examples of glide ratios for twins. The Glide Ratio calculator computes the glide ratio based on the change in forward distance and the change in altitude. No answer. Not to mention a "what the heck, let's roll it airplane." WHAT WILL THESE CHANGES DO TO OUR TOUCHDOWN POINT? How to stop ignition interference on radio. :) keep up the good job. Its the added speed that balances the extra drag, Can you or anyone judge 6.01 deg glide path (not angle of attack) 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. 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. 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! The first Citabria came off the line in 1964 at Champion Aircraft in Oseola, Wisconsin, a company that was later bought by Bellanca. I believe the 172 is 9:1 and the 182 is 10:1. Page 6-Engine Out Glide Distance? If the C-172 has an L/D of 9.5. Because the AOA remained unchanged, this once again perfectly balanced plane will remain on its same glidepath and arrive at the same touchdown point. All airplanes are designed to be able to glide to anticipate the worst case when the engine is failure. THE ONLY THING WEIGHT DOES IS BRING THE PLANE DOWN THE GLIDE PATH AT A FASTER RATE. Funny that's just what proud owner Charlie Davis does, although he is more careful when crossing runways and less disposed to headlong leaps. The 7GCBA (ag spray plane) is certified to 2400lbs (I admit I know nothing about it's structure). Glider: SchleicherASK 21Tail #: Both aircraft will cover the same distance but the lighter one will take a longer time to do so. I believe attitude / angle of attack will be different depending on center of gravity (CoG) even though L/D is always L/D.

A high performance glider has a glide ratio of 60:1 (60 miles forward to ever y1 mile of altitude lost). Views: 812 Thats why planes have gross weight limits. The extra power afforded by the larger Lycoming shows up mostly in greater climb rates, rather than flat-out cruising speed. 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 . Some will find it easier to use a different calculation. Cleveland - 062-00300 - Piston. Keep in mind, though, you're going quite a bit slower than your best glide speed, and that can significantly impact your glide range. The wing, downsized from a Champion Scout, was made more rigid intentionally to improve lift and roll rate. Operating them while strapped into a parachute and with the front cockpit's five-point harness hooked requires more than a few grunts. No warranty of 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.
