citabria glide ratio
The major differences between the7GCAA and 7KCAB were in the fuel system and the engine oil system. No warranty of The cross-section of the metal fuselage truss is triangular, a design feature which can be traced all the way back to the earliest Aeronca C-2 design of the late 1920s. Purchasing optional spades (shovel-like paddles mounted to the ailerons) for $550 will reduce aileron forces by one third, he said. This airplane is certificated in the normal and acrobatic categories. A glider improves its glide ratio relative to the earth by speeding up if there is a headwind, or a downdraft. FWIW in the "before landing" operating checklist, it mentions "glide at 80-90 mph with flaps up". Useful Load: 550 lbs. But a lovely bird. 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. But the best glide speed for the SR20 is put close to 100 knots, with the DA40 at 70. Champion introduced the 7KCAB in 1968. L=cL(1/2 x Rho x v2) S. Higher weight requires higher lift. Prop stopped, which helped the glide ratio quite a bit. 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. 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. 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. 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. 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. Like the 7KCAB, the engine of the 8KCAB has a fuel injection system, as opposed to a carburetor. See the airplanes P.O.H. Cruise Speed/Endurance with45 MinReserve @ 75% Power: 127mph/ 2.8 hrs, Fuel Consumption(55% to 75% Power, per Lycoming Data): 7.3 to 10gph. The SGS 1-26 enjoyed a very long production run from its first flight in 1954 until 1979, when production was ended. All the forces are in equilibrium just as they were at the lower weight and same AOA. whether the flaps are deployed, the landing gear is down etc. They're located in Rochester, Wisconsin (262-534-6315), or on the web at www.amerchampionaircraft.com. Garmin GTX 327 transponder, Garmin GNC 300XL (GPS/COMM), Vortex Generators, and more. Older Citabria 7GCBC aircraft produced in the 1960s and 1970s had wood spars that are prone to cracking. In that period, only one Citabria model was builta 7GCBC marketed as "Citabria 150S." 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 magneto, master, and other switches are, like the older models, rather inconveniently located behind the pilot's left shoulder. 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. If you have a GPS just hold an airspeed, throttle back, decend a fixed amount and see how far you went. Remember weight does affect stall speed. All rights reserved. Maximum speed: 162 mph. It is still being produced. Landing Distance over 50-ft. The glide ratio varies with air speed, but there is a maximum value which is frequently quoted. (35 gal. American Champion Citabria 7ECA Pre-Cut Carpet Kit. What, if any, specialty instruments are used for professional glide ratio testing (such as a manufacturer developing a new model)? Welcome Guest. Overall, the aircraft delivers what it promises: fun. Tracking the runway centerline required little effort. Aircraft Serial Number1335-2002. American Champion Citabria 7ECA Pre-Cut Vinyl Floor Kit. You can round 9.11418 down to 9.1. Also, there is no thrust to move the aircraft. Examples of how to use "glide ratio" in a sentence from the Cambridge Dictionary Labs Bill Piper really needed to have someone shot over that! 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. Instead of best glide SPEED, memorize best glide ATTITUDE. Bank Angle 45 and 45 is what I was told. Airspeed-65 MPH recommended (60 MPH minimum) 2. Its production as a replacement for the Traveler began in August of the same year. 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. HOLY COW!! To take advantage of the new light-sport aircraft category, the Champion was returned to production in 2007. It has a claimed maximum L/D = 41. Instructor: Scott Williams. The Glide Ratio calculator computes the glide ratio based on the change in forward distance and the change in altitude. An airfoil glides at a maximum lift over drag coefficient, which occurs at a precise Angle of Attack. 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. Aircraft I would like to know the actual glide ratio of my airplane at several combinations of configuration and airspeed. Do you disagree? So Joe, Jim and Paul are correct but they have not told us how they determine Its name spelled backwards, "airbatic", reflects this. Probably closer than you think. The pilot did an awesome job, cool as a cucumber. Description: The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. One of my favorite civilian birds of all time.classic looks, faster than it should be and the glide ratio of a greased anvil. Like the Champ, the Citabria features tandem seating. Disclaimer: Information on this site may not be accurate or current and is not valid for flight planning or any other aircraft operations. This frees you to make the decisions and troubleshoot. Champion's first Citabria flew as a prototype in May 1964. When introduced, it featured wood-spar wings and oleo-shock main gear. By continuing to use this website, you are agreeing to our Cookie Policy. The weight is no longer a factor in this scenario. BUT ONLY IF THE PLANE WAS DESIGNED WITH WINGS TO SUPPORT SUCH A LOAD. 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). I fly over a huge area of good LZ's. An orificed one-way check valve allows a minimum of fuel to be vented overboard during negative G aerobatic maneuvers. Empty Weight: 1200 lbs. No answer. Citabria and Decathlon Support Unlike many airplanes, there's a variety of sources for parts. The winds would have to be factored in as well. lighter. Then add a metal prop or a starter and battery, and a wing tank . Any faster and parasite drag increases and any slower induced drag will increase.. 5. I'll bet there are some out there. In other words, the Angle of Attack for best glide will not change. Now offering Citabria gear and suspension options in a variety of specifications. 40 or more to one for single seaters has been common for 30 years or so. The landing gear of the Citabria is in a conventional arrangement. Why should I think its not on the exact same glidepath now? You are using an out of date browser. Throttle - CLOSED when in gliding distance or runway 3. Gliding Distance is given by. Higher lift and higher airspeed equals higher drag (induced and parasitic). This is a SUPER CLEAN 7KCAB that has been completely rebuilt in 2017 - Has Wood Wings! What gives? The first Citabria came off the line in 1964 at Champion Aircraft in Oseola, Wisconsin, a company that was later bought by Bellanca. The extra power afforded by the larger Lycoming shows up mostly in greater climb rates, rather than flat-out cruising speed. 2. Locate a Dealer. TO OUR GLIDE RATIO (AND ITS RESULTANT GLIDE SLOPE)? Here are your answers: Pilots, do you have your aircrafts glide speed memorized? There were 1,214 Citabria 7GCBC aircraft produced before Bellanca Aircraft Corporation ceased production. [2] It was a parasol winged monoplane, with a revised wing section and a longer fuselage. American Champion has been using aluminum spars in the aircraft it has produced and has, as well, made the aluminum-spar wings available for retrofit installation on older aircraft. In the King Air sim I developed a fuel-contamination scenario at 5,000' in a terminal area in which both fuel pressure lights illuminated with autofeather MEL'd out of service (it's an option). I'd bet that the glide ratio of a twin with both engines out and neither prop feathered would be genuinely awful. The main gear legs of most Decathlons are made of spring steel, though American Champion began to use aluminum gear legs in 2004. Come on Paul. Someone on the internet gave a Vbg of 135MPH for a total glide time of 60 * (6/135) = 2 minutes 40 . . Why? 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. Since its reintroduction, the Super Decathlon has sold steadily. Is posible descent the same distance from the same altitude and land at the same point with diferent angles? i dont see it. Instructor Davis said the aircraft requires a long, flat approach, but that was inhibited somewhat at Warrenton by trees off the approach end. The 7GCBA (ag spray plane) is certified to 2400lbs (I admit I know nothing about it's structure). You have to explain that a little better than that. It can be used for spin training with tailweights added. Probably displaying my lack of understanding. Bellanca continued production of the Decathlon throughout the 1970s, moving to the Super Decathlon variant during 1976. The 7GCAA . Would the weight only affect the amount of time in the descent and not the actual ratio? for approved maneuvers in the acrobatic category. This should be a indicated airspeed you should try and maintain the second your engine quits or starts sputtering. Really ? Which airplane will arrive first to the ground? ). The strut-braced wings of the Decathlon are, like the fuselage and tail surfaces, fabric covered, using aluminum ribs. (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's fair to say the Citabria goes back a waysall the way to the beginning, in fact. Power Plant: Lycoming O-320-B2B. Wing aspect ratio: 6.72; Length overall: 22 ft 8 in (6.91 m) Height overall: 7 ft 0 in (2.13 . Sorry, JavaScript must be enabled.Change your browser options, then try again. Yes, L/D is L/D always. 3. To emphasize a glider term, sink rate matters. Center of cabin to wing tip 16.75 feet. N234WE, Tow: American ChampionCitabria 7GCAA Sn#:2Tail #: 1. A typical commercial airliner will glide at a ratio of about 3:1. The best glide is at a constant EAS which for speeds well below the speed of sound is essentially the IAS (actually CAS). Aircraft specification no. Available in several versions, with varying powerplants and equipment, the Citabria and its stablemate, the Decathlon, have a great deal to recommend them to the recreational flyer. Fuel Capacity: 36 gal. The Citabria POH/AFM is a piece of junk, isn't it? 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. the glide ratio is independent of the weight or mass of the aircraft. Best glide ratio is the most optimal - the highest - one. Ceiling: 17,000. Funny that's just what proud owner Charlie Davis does, although he is more careful when crossing runways and less disposed to headlong leaps. This describes me. Reissued 08/14/2012 SA2683NM Installation of Precise Flight, Inc. stand-by vacuum system (SVS) Probably closer than you think. Champion introduced the 7GCBC in 1965. The Aeronca Model 7 Champion, more commonly known as the Champ, is a single-engine, two-seat, fixed conventional gear airplane. The glide ratio varies with air speed, but there is a maximum value which is frequently quoted. Yippee! Thus, the only remaining variable left to change our lift is velocity (V), or airspeed. 1. Use tab to navigate through the menu items. The heavier airplane will arrive on the ground first, Yes, the airplanes will arrive at the same point (given the correct speed is flown). If the C-172 has an L/D of 9.5. In this example, the glide ratio provided in the POH comes out . 8-10:1. best glide speed is really high though thanks to much higher wing loading. $85,500 Reg# N8552V TT: 2408; Performance Specs. An extremely expensive, highly competitive glider today can have a 60:1 glide ratio. Sign in What weight do they use for the normal calculations and would that matter? 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. ? Holy Smokes thats a good question! On this Wikipedia the language links are at the top of the page across from the article title. 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. When the Citabria was introduced, it was the only airplane being commercially produced in the United States which was certified for aerobatics. Not to mention a "what the heck, let's roll it airplane." Ours was built in 1984 and purchased from the Wings of Eagles Museum. Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from +5g to -2g. Agree, especially if you mean the hershey bar variety. Decathlons and Super Decathlons remain popular as aerobatic trainers, as beginning and intermediate aerobatic aircraft, and as personal aircraft. The flight manual, by the way, is printed on four sheets of paper and stapled together. 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 The glide ratio is based only on the relationship of the aerodynamic forces acting on the aircraft. Like the original, it can handle a hefty 17-knot crosswind. Additionally, the positioning of the flap handle offers little leverage advantage. Drag is apposed by thrust. Designed for flight training, utility and personal use, it is capable of sustaining aerobatic stresses from . History. In addition, metal ribs were nailed to spars, but the nails would pull out. (Probably similar to the "pregnant brick" mentioned earlier.). GlobalAir.com is your partner in connecting you with relevant information and resources. YOU GET THERE QUICKER. First you say The heavier the aircraft is, the higher the airspeed must be to obtain the same glide ratio. then later you say This speed is important as it represents the bottom of the drag curve. Early Citabrias were fitted with a steel tube main gear which uses an oleo strut for shock absorption. It was substantially similar to the 7GCAA of the same year, with wood-spar wings and spring steel main gear legs. Would it be the same as your best climb? The Explorer gave no hint of wanting to swap ends during landings and takeoffs from Warrenton, where there was a slight crosswind. The Citabria traces its lineage back to the Champ. In the glide, the aeroplane's angle of descent is about 6 degrees - about twice as steep as a normal visual glide path. glide path. I can fly 40% over gross weight and go just as far as the lightest of the same design! 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) 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. 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! Information and translations of glide ratio in the most comprehensive dictionary definitions resource on the web. Higher is better. We powered pilots often call this Vg or Vbg. One of these aircraft is displayed at the Rahmi M Ko Museum in Istanbul. Most think this is blasphemy, so take it with a grain of salt: tan(glide angle)=alt/distance. I would really appreciate if you could help me out. 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.. NO OTHER CHANGES. The most noticeable external changes to the design are the Citabria's squared-off rudder surface, wingtips, and rear windows. Login required to see more detailed info on each aircraft. 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 Decathlon traces its lineage back to the Aeronca Champ, by way of the Citabria. 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. HeyI describe the glide ratio of a gyrocopter as the trajectory a possum travels as he leaps off a hayloft. I do most every landing with engine idle, so I obviously know the drill. The Champion 7ECA Citabria was a modernized version of the Champion Model 7EC Traveler. Aircraft weight, air density (e.g. Aircraft.com is the leading registry for planes, jets, and helicopters. Nationality and Registration MarksZK-CIT. 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. The only effect weight has is to vary the time the aircraft will glide for. Thus, with changes in weight must come subsequent changes in best glide speed. 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." In 1967, Champion switched to spring steel main gear legs; by then, the Lycoming engine had become the standard. There is a forward component of weight (relative to Drag) that moves the aircraft forward. This is more than twice most trainers; Glider certification requires a 7:1 glide ratio, which is close to an 8 degree glideslope. The American Champion Super Decathlon uses the AEIO-360-H1B, along with a constant speed propeller. 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. So I'd guess best glide speed is 80-ish. The Citabria design based on the Aeronca 7AC Champion. 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. (You must log in or sign up to reply here. The added weight requires more lift. 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. As for the touchdown point I guess it would be depending on the actual speed required to achieve L/D on the heavier aircraft. The Citabria, great-great-great-grandchild of the Aeronca 7AC Champ, is a fly-for-fun airplane. Fuel quantity is registered by two direct reading float type gauges, one for each tank. People should practice engine-outs by landing with idle power whenever possible. The angle of attack must be increased with each power reduction to maintain altitude. This glider was rebuilt by Chuck Zabinski and Jake Smith. Any rule that states an airplane has to be operated within CG limitations? Cruise speed: 126 mph. In GA aircraft, the speed is given in reference to the max weight. Login . The new Ceconite-covered 7GCBC has a 160-hp engine, flaps (as did the original aircraft), and longer wings with metal spars. . View photos, ownership, registration history, and more. ). 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. 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. How to stop ignition interference on radio. The landing gear of the Decathlon is in a conventional arrangement. 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. Said for years..every pilot should know his best glide, write it on your dash. What else should I plan for, in checking this? 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. And it means you have more vertical speed to arrest in that latter phase. Cars only need 20-40 HP to maintain highway speeds. 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 plane must increase speed or AOA to make more lift.) 2023 GlobalAir.com. Bellanca introduced two designs with close connections to the Citabria: The 8KCAB Decathlon and the 8GCBC Scout. Champion switched to spring steel main gear legs in 1967. The prototype had an open cockpit for a single pilot, but the design allowed for conversion to a two seat layout. 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. 4 products. 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 . So based on the information above. Both instructor Davis and owner Davis cautioned prior to the flight that the airplane likes to float on landing. The main gear legs of most Citabrias are made of spring steel, though American Champion began to use aluminum gear legs in 2004. Both at the same time? (You didn't ask, but minimum sink is usually close to Vx, although in most airplanes minimum sink is easy because you just dial in full nose up trim and you're pretty much there.). Now that I think of it, I could carry an extra 5,000 lbs. It's based on the Champion 7-series airframe. C) remain the same "It reduces a lot of problems," Mehlhaff, Jr., said. Your glide ratio needs to be determined empirically. Compared to the Citabria's wingspan of 33.5 feet (10.2m), the Decathlon's wingspan is shorter, at 32 feet (9.8m). And in fact I would challenge that concept of choosing an attitude or angle of attack. Airplanes fly on excess power, not grace, not engineering. The Citabria is based on the Champion 7-series airframe. On acquiring the design, Bellanca gave this model the name Citabria "Standard" and began using the 115 horsepower (86kW) Lycoming O-235-K2C engine. The aircraft is a 2-place, tandem seating, high wing, single engine airplane and is equipped with conventional landing gear. It is applicable to Serial Numbers 1240-98 and up. Production history [ edit] The Glide Ratio is the ratio of distance forward to distance downwards when a glider is flown at a constant speed in still air. Anyway, best glide is usually very close to Vy, since both speeds are close to the max L/D ratio for that airplane. For example, a 50:1 glider will fly 50m for every 1m it drops. 32032 Washington Ave. Burlington, WI United States 53105. 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. Perhaps I am to understand that angle of attack stays the same in best glide, A little extra airspeed has minimal effect, but a little too slow is bad. Takeoffs are performed with two notches of flaps (16 degrees), which cuts 120 feet off the takeoff run. Wow! One glide I did from 7500' down to the surface at ~800 MSL resulted in an 11.54 glide ratio. Airplanes fly on excess power, not grace, not engineering. Ours had all spraying equipment removed. Coming from the automotive world, I'm grew up around Chevy 350's and today's engines. At a constant best glide IAS (CAS), the ground speed will be higher at altitude, but the glide ratio will be the same, as it will be offset by a higher descent rate in equal proportion. 10-11:1 otherwise. ? that specific attitude. SAVE Last Update: 02/24/2023. Our glider has blocks that can be rotated in front of the rudder pedals to accommodate shorter legged people. It may not display this or other websites correctly. Dec 19 2022. I just read elsewhere that altitude / air density does not effect glide ratio but it seems your explanation says it does effect glide ratio. 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. How far they go forward versus how much they drop is the glide ratio. The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. by the manufacturer or FAA. Vy in your airplane is 69 mph. N70FP SN#101A202, Glider: SchweizerSGS 1-26ATail #: The large wing area gives good low-speed handling characteristics, docile stalling characteristics, a excellent climb. https://en.wikipedia.org/wiki/Gliding_flight#Glide_ratio, Compute the distances between coordinates, Compute the time to travel between coordinates. The Citabria is a light single-engine, two-seat, fixed conventional gear airplane which entered production in the United States in 1964. This can be the difference between going home ! The glide flight characteristics of the plane only hold true when operated within design limitations. 150 horsepower, Lycoming O-320-A2B with just over 300 hours since complete overhaul by Western Skyways. No Oil Required altitude) have no effect on the glide ratio. SECOND THE SPEED VARIABLE: I know the AOA did not change. Per the C180 owner's manual, sea level best rate is listed as 87 - 90 mph. (You must log in or sign up to reply here. Like the Citabria, the Decathlon features tandem seating and center-stick controls. How do you determine the best engine off glide ratio in a gyro? Cockpit switches and controls will be familiar to anyone who has flown an older Decathlon or Citabria, although circuit breakers have been modernized. 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.
