Reduced landing flaps is a very common fuel-saving best practice. Don't try to climb with flaps down. The proper choice of flap system for an airplane arises from which part of the flight envelope […] I’m a beginner still. It’s not aircraft specific as to the notion of the pilot needing to decide whether and when to use full flaps, partial, or none on landings, unless your bird lacks flaps altogether as some of the ancient aircraft designs did. Then add 10 percent to that if you have to land over a 50-foot obstacle. An additional beneficial effect of extending the flaps is a reduction of the aircraft’s pitch angle, which lowers the nose giving the pilot a better view of the runway. Airspeed is king and as long as you keep the approach speed where it should be, the flaps do nothing but steepen the approach- not an issue for the flat terrain here in central Wisconsin. For example at my home-drome (6880 MSL) a full flap landing with just me in my straight wing, "short stabilator" Arrow simply begs for an "arrival" rather than a "landing". Once you get to the key point use what you like. Also, it is always good practice to stay current in making partial or even no-flap landings – not only to handle gusty crosswinds, but also should you be forced to make a no-flaps landing in the case of airframe icing. For Cessna (up to 182, I’ve never flown heavier), I plan for 20 degrees and deploy 30 if necessary except for soft, short or both when you need 30. Start with the landing distance specified in your POH. However, nowadays pilots get to land an Airbus 320 with a total time of 300 hrs with 200 hrs on Cessna 152. Among other aircraft, I fly a C-188 which is of course a tailwheel plane. Sooner or later, many RC modelers try their hand at a scale subject, and since most full-size aircraft use flaps, their scale model should include them as well. You should seriously consider planning for these factors in any marginal situation. Second, there was about a 12-knot crosswind that night, and I wanted to see how he handled the situation using full flaps when it was dark. Aircraft Owners & Pilots Association Find it free on the store. I think I’ll simply stay flexible at the moment. Pushing the nose down, altering course a little to the left, and I assume maintaining significant power, the airplane was able to land WITHOUT FLAPS. Using full flaps is a very high drag and very poor L/D ratio configuration for the plane to be in. 2. Except for very short runways much shorter. I need to try the options, and get a lot of opinions from experienced folk. This was "just a little climb" after a partial-flap touch and go with a student at an unfamiliar airfield (for him) in the Northeast. After a takeoff run of basically nothing, the plane was airborne. NOT away from the home field and practicing apph and or landings. Then, go fly a fuel injection equipped plane. 3.) On the other hand, I flew a Grumman Tiger, great plane, fast, great handling and all, but you might as well forget that it has flaps as they do about nothing. Less wear and tear on the tires and gear, shorter rollout distance, and less opportunity for gusty or swirly winds to mess with your rollout, or lift an upwind wing, etc. When performing a normal landing, do you prefer to use the full flap range of the aircraft, or a partial flap setting? Don't try to take off with the flaps full down. Going no flaps on a B 727 requires like twenty miles of runway, not that I fly them but my brother in law did and loved that hot rod three holer. My guidelines are just what I’ve found works the best with my new students. Hi. So, how much runway do you have? Plain flaps hinge to the back of the wing, and they pivot down when you extend them. Sort by votes; Sort by date; Recommended Posts. Throw out the dog and tent. I don’t use intermediate flap positions. But as anyone with any significant flying experience knows, strong and/or gusty crosswinds demand responsive flight controls which in turn demands a higher landing speed. My super cub likes river bars and sand bars the best. Last edited by airbus_driver319; 3rd Jun 2013 at 20:56. It depends on the plane you’re flying, the landing field you’re using, its length, floor type, obstacles you have, wind, the capability of your plane to go around with or without flaps. And I think it might be simpler for me to remember on a go-around to push BOTH throttle and carb heat in. Mac. New to Air Facts? In fact, there are 4 primary flap designs, and each of them have advantages and disadvantages. As I have no problems landing with partial flaps, I rather like the idea. It's easy to see how not knowing ahead of time can cause all kinds of problems. Now let's return to what the British CAA says. Have to balance airspeed, wind conditions, crosswinds, full passengers or solo, many different aspects to consider when landing. Does it depend on the airplane? A good landing begins with a good approach (see below). He wrote that once in Flying Mag about his Mooney. Using AOA I have no problem landing comfortably using this technique – wet grass and all. If you land without flaps, it becomes 1,762 feet--more than three times the normal landing roll with full flaps. Carry power with full flaps on the approach, chop the throttle and dump the flaps at touchdown, (or when the mains are within about a foot of the ground and you are over your touchdown point). Flaps greatly reduce its landing speed. Carry power into the flare, and keep the fan turning even after the main landing gear touch the ground. Since then I always plan for the same happening to me. Flap 30 is the default flap setting for most operators, reduces loads on the flap so they last longer, they provide better noise abatement as you don't need as much thrust which also saves fuel! My partner and I have practiced various flap settings on approach. He is a Gold Seal CFI who has been instructing for more than 30 years and flying for more than 40. Don't be caught flat-footed in a situation where you have to employ a slip and you are unsure how to do it. I don’t know your age, but you are very wise in your understanding of the adverse possibilities (balked landing and go-around). Category B - 1.5 NM • Required visibility - Add one (1) SM of visibility to the stated circling approach minimum visibility. I normally operate in a 2300 feet x 40 grass strip and a 30* flap landing is more than enough flap position for short runways. However, certain conditions may prevent applying it: High altitude airports; Short runways By far the most important reason for this is that crosswinds affect the upwind wing more because of the increased lift on that wing imparted by the extended flap, compared to the wind-sheltered wing, and the seeming stability imbalance. Then set up your approach And give it full flaps dragging it in behind the power curve. But what do you do when you're confronted with having to hit a specific landing point on a short runway, and a crosswind exists? A good friend of mine lost his engine on final and failed to make the runway, which cost him his life. This needs to be narrowed down a lot, just too many variables. I have instructed in several places and noted the airline and military approach are the ones who use only 1 setting. Full flaps are nice, but low-wing airplanes may have ground clearance issues in tall grass or uneven ground. I have also been a computer airline captain and flaps greatly reduced airspeed and the landing distance which made landing in Aspen Colorado much safer. If used for takeoff, use only partial flaps. +1 Votes 1 Votes 0 Votes. I haven’t needed a slip in 30 years, and never had an issue. Practice slips to become proficient. A scale model with the flaps fully deployed is an impressive sight. Finally, consider using less than full flaps when landing in a gusty crosswind. So you have a slightly higher approach and landing speed, but you aren't blown as much to the side as you would be with full flaps. It depends. Flaps are part of wings of an aircraft and they are engaged to create a drag during a landing or a take-off. I did have a carburetor freeze on me just after takeoff on a humid 83 degree morning. I don't think he'll ever forget that one. This so depends on the plane. Usually airline and military planes have to optimize their runway because they require so much runway to land and they have a powerful engine capable to compensate the drag created by flaps in case of going around before or touching the runway, we have to remember that they use usually better runways than general aviation aircraft, and they have less risk of an animal, person or vehicle to cross the runway area, when you are in unprotected places you do prefer to land with lower speed, and require less runway. It's considerably more "draggy" than F30 and you'll typically need 6-10% more N1 to maintain VREF + wind additive on final approach. Sure, when I flew the 727, flaps were a necessity, but not always full flaps. At one point, the airline started an initiative to use flaps 22 landings as a method to save fuel with lower power settings on final approach. Then there was the time in my young instructing career when, at 40 to 50 knots or so on another touch and go, the tail came off the ground but the nosegear didn't! For what it’s worth, most airline and corporate aircraft always land with full flaps but they may add a speed increment for strong winds and gusts. The major differences include approach speeds, speed stability, pitch attitude, the flare and landing … Went west to the Atlantic, down the coast almost to Newquay, then turned eastward, up the channel and back to Bodmin. In my earlier post I mentioned running out of elevator - what I meant is that when landing with full flaps and the engine at a low power setting I found that the elevator went away before it felt like it should. If you know your airplane, all it takes is pitch and power. With a Mooney speed control is everything and if you nail your speeds you don’t need flaps, the bird will touch down like an eagle alighting on her nest to feed her young. Extend flaps to the second increment. If you are high or in tight enough that will use flaps anyway, putting them out will help you get “around the turn”. I think it’s good to learn how to use full flaps, and to be comfortable with it as sometimes the strips won’t be as great as the ones you learned on. *** when your plane is full of fuel, it will be heavy, and will not stop in time. In rough numbers, the breakeven point is 900m for A320 and 1700m for A319. No flappers are important too, I’ve had a flap failure before. This will most likely be the pilot’s first exposure to flaps … Partial flap landings aren't too common in general aviation, but here are some reasons you might decide to not use your full flap setting. Brown pants was a possibility. The cause of most landing accidents, no matter the wind condition, is not control of the airplane on final. It's completely free, and we will not share your information with anyone. Landing on a short field and clearing any obstacles on final approach entails setting up a stabilized full-flap approach at the recommended short field approach speed for your airplane. Generally I use full flaps (slows the touchdown speeds and saves on tires). Full-size planes have their air speed indicators marked for safe flap operating range. I tell my students flying 152s and 172s that 20 is normal, 0-10 for xwinds, 30 only if you are absolutely too high or too fast on final, 40 for actual short runways (3000 ft isnt short). Gone solo. By raising flaps the potential increase in tire grip (from reduced lift) for braking is offset partially or entirely by the reduction in aerodynamic drag. In any landing, the pilot must be established on final approach. Then when landing you gradually lower the flaps by stages usually on descent after you have turned to line up as you get slower (usually with throttle off to slow down), until you are on full flaps for final landing, so you are going as slow as possible without stalling. Check your aircraft's POH for the corrections you should apply. FWIW, there’s 2 Steves, so I added an initial. To access the leaflet online, see AOPA Flight Training's online links page. The old Nissen huts and camouflaged control tower are still there – as a little museum. Flaps raise your lift, but raise your drag as well, in a strong wind condition they, big planes, are less affected than your Cessna 150. But full flaps can also cause directional control problems on landing in a crosswind. Cheers, Quote; Link to post Share on other sites. It will lead you to controlled landings. I now fly a DR400, very nice, but not the same. In the end, every landing is different, and you’ve got to know your aircraft. Very good learning experience….. You learned a lot. Join thousands of other pilots - sign up for our informative email newsletter. Wing flaps change the shape of the airplane wing. Moira, After all, how much flaps you use really do make a difference. If winds or any other factors do not permit that, then it would be the next best thing. Last edited by airbus_driver319; 3rd Jun 2013 at 20:56. I say depending on the condition. With a crosswind, the faster an airplane flies, the less the crab or slip required. It was an American air force base in the 2nd world war. Cherokee flaps are pretty fair but if you want to get into someplace really short with four on board the old hawk is your bird. If it is 5-6k, full flap and tighten your belt and hit the heals. I’ve set the flaps in a turn also. My father was the same way, so that might also have something to do with it. The most simple flap is the plain flap. To that, you add another 20 percent in a tailwind for each 10 percent of your landing speed comprised by the tailwind. I was lucky and had to learn how to land accurately and short right from the get go. The normal ground roll using the procedures described in the handbook is 1,068 feet. Over the past year, I have experimented with a range of flap settings under different conditions and decided that while it is essential to be feel comfortable with full flap landings, they are not the best for everyday approaches. Personally I don’t like full flap. Hi all, I bought the Hornet recently and Im practicing carrier landing. The big deal can occur with respect to flaps when there's an obstacle, gusty crosswinds, and you're carrying extra airspeed. Let me clarify, I though the discussion was the use of slips for the descent profile in place of flaps, not a slip for landing as one is rounding out. Full power and the plane just sat there at about 50 knots and was not accelerating. But, sometime – just for fun – I would like to try Gordon Baxter’s idea of full flaps to the flare and then take out a notch to paint it on. Later models have a detent and offer three positions, up approach flaps, down. One factor to consider when … The resultant landing accident is caused because there is less rolling control than the pilot anticipates. If you're not comfortable with no-flap landings, or haven't done any for a while, tell your flight instructor that you'd like some practice. Especially in aircraft like Cessna with such large flaps. Since the 1950s, most airplanes have been designed with wing flaps, allowing for steeper approaches, better sight pictures and lower airspeeds at touch down. Steve, I am guessing that where you fly there are no crosswinds. A319 burns 16 Kg more for a Flap Full landing/A320 burns 9Kg more for a flap full landing. Go,around in a 40* flap in a hot and high elevation airport is also very easy to have an accident. In my opinion, the flap degree depends on the wind, I have made landings without flaps due to the wind speep and on the other hand I have had to make a landing with full flaps. It is usually a full flaps landing. With flaps, he probably would have landed, backwards, in Canada. 6th Jun 2013, 16:44 #58 vilas . Hence, you run into the speed limitations of the high flap settings. Moral of the story, keep that carb clear of ice, at times with heat, and/or fuel. But those planes love a slip. It doesn’t add too much to the landing roll and it’s easier to land in some ways. You shouldnt need flaps at all when flying around normally. Some POHs say something about flap use in cross winds… some don’t. 40 or 30 degrees no problem or in the case of Cirrus aircraft I include practicing landings with no flaps as there is a common failure of the flap relays. I always go immediately to 20 degrees, then 10, then 0. Of course, the down side to the instant flap dump of the Cherokee is that an inattentive pilot can also dump all of his/her flaps instantly too. 2.) Use Full flaps. Should you land with full flaps every time, or are partial flap landings easier and safer in windy conditions? mvivion . Then use half flaps. Which Is Better, Full Or Reduced Flap Settings On Landing? No flaps when there’s a lot of wind. The POH says full flap is ‘normal.’ I can see an advantage in the 20 deg flap landing – as if the electrics go when you’re on 30 deg you’re stuck with 30 degrees – and a go-around might turn into a not-go-very-far. But that seemingly small spread is really something big to think about. I have to…. plane will still climb with carb heat but once on the ground, it is a good idea to keep your wheels stuck to the runway (hence the reasoning in bringing up flaps). It felt as if I needed some weight in the baggage area to get the cg aft a bit. This gives the pilot a better view of the landing area. Further, I always prefer the armstrong/handle bar flaps over electric ones. Full flaps as needed or when landing is assured. Dean’s advice is good advice. His moment of indecision could have meant real trouble, especially if he'd been solo. Go-Arounds / Rejected Landing Procedure Full Power, carb heat off (as required) Flaps 20˚ Eyes outside – pitch to horizon, positive rate of climb Flaps 10˚ Accelerate to V Y (or V x if required for obstacles) Flaps 0˚ (after clear of any obstacles) Resume normal climb out Key Reminders If you happen to have a 50-foot obstacle on final approach, landing distance then becomes 1,305 feet. The landing approach is very different without flaps – not only are the airspeeds significantly higher, but the deck angle and visual references are very different. Most of those airplanes would fly with 40 deg flaps but barely! However, I rarely used 40 d because there was no benefit and lots of negative. Side slips with or wthout flaps are a good maneuver to master and understand during cross wind landings and take offs. The procedure I have always followed is to bring in all available power (throttle up), carb heat off allowing maximum fuel flow into the dried out carb, establish adequate rate of speed, retract flaps in stages, and then climb out. In a Supercub on a cross wind gusty day it real hard to keep the plane on the run way. Sign up for our free email newsletter, packed with tips, tricks and news for pilots. “The Green 172” goes to 40 degrees of flaps! No need for ’em in heavy cross wind and they just make it tougher on the inexperienced student. Flaps, regardless of the type installed on the airplane you fly, do make a difference in the way the airplane flies, especially on takeoff and landing. Landing flap settings are at the pilot's discretion, although this article will outline what a variety of sources say about typical situations. I do not necessarily recommend that, just personal preference. Besides, most Pilot’s Operating Handbooks point out that “normal landings” are with full flaps. This aircraft has two flap positions in addition to zero flaps (3 position switch). Forward slip – FAA mandated In some cases, a little extra speed is beneficial, and most Cessnas don’t need 6000 ft. of runway to get stopped anyway. Landing speed 45. Please login below for an enhanced experience. Turn final. Avoiding slips with full flaps; Avoiding slips for prolonged periods of time which may result in fuel ports becoming uncovered ; Airspeed indications may vary due to static ports receiving direct wind If your static port is located on the left side of the fuselage, a slip using right rudder will cause the perceived static pressure to be higher than actual as ram air is forced into the static port, resulting in your indicated … At my airline, we generally use full flaps (flaps 45) when landing the EMB145. But the remedy is simple--just know! P.S. numbers – – and never a problem with no-flaps. The major differences include approach speeds, speed stability, pitch attitude, the flare and landing distances. ©2021 Aircraft Owners and Pilots Association. The airplane floats and floats before it touches down. I kinda prefer forward slips and they’re the only descent control I have on my Alon Aircoupe at idle throttle. Flaps 3 may be used for take-off in the case of a short runway or obstacle clearance. Longitude full flaps landing speed? Oh geez. Copyright 2011-2021, Sportsman's Market, Inc. From the archives: Checkout in a Spitfire, Remembering Pat Luebke, Long-time Air Facts Managing Editor. If I have to go around the prcedure is much easier to execute if the flaps are already set to climb and the carb heat is already off, which I turn off after turning final. If your flaps fail to extend, you will obviously be forced to make a landing without them. Given his former-jet-fighter-pilot preference, I knew he would land without flaps every time. I learned to fly in the Mile High City where the ground speed is higher than the indicated airspeed. Can’t comment about military. I trained on a C150. But the Arrow POH gives no way to compute the no-flap landing distance. Add to this a crosswind pushing against the vertical stabilizer, and the airplane can weathervane seriously into the wind. The shifting surface winds can be problematic resulting from airflow over a small mountain just off the runway. We watched in amazement as the huge barn-door flaps remained stubbornly full … Flap position 1 (or 1+F to be specific) or 2 is most often engaged during takeoff while flaps 3 or flaps FULL is selected for landing. I use one notch beam the numbers and full on final if too high. I find that 20 degrees of flap gives me more control, especially in terms of increased rudder authority when needed in crosswinds. You shouldnt need flaps at all when flying around normally. With a 50-foot obstacle it becomes 1,525 feet (nearly two and one half times the no-obstacle ground roll). . This can be applied to any airport when Flap 3 will result in different exit point and longer taxi routing. Good practice makes better. Don't think so. Every time. I think you are right. The general rule is to use full flaps for most landings--but it depends. January 16, 2021, 10:36pm #1. No flaps, little flaps, full flaps, wind, no wind – no problem. Unimportant? It’s the go-around I worry about. Plus they help reduce the takeoff distance. Remember, you just cut the power, hence less fuel in the carb and potentially deadly moisture. Hold the stick full back and stand on the brakes as hard as you can to hold the tail up without flipping on the nose. Full flaps or partial flaps? Sure, it can be done, and I wouldn’t hesitate to do it when approaching a short field, but the number of bent 182 firewalls suggest that many pilots don’t do it well. The stabilator equipped Thorp T-18 homebuilt had to have a flap limitation added due to stabilator stall in sideslip (John Thorp did some testing after an incident in the 60s, discovering that the stabilator could stall with full flap, forward CG and sideslip, causing a nasty pitch over, and advised owners not to use full flap for landing). Second I see wind-shear cautions and heavy crosswind component, no flaps are used (occasionally 10-degree or half that). From time to time, we will change our configuration based upon landing weight and significantly higher density altitude. My home airport is a lighted 1,800 grass strip ten miles SW of ICT. If anything it’s good training in case of electrical failure. Once obstacles have been cleared and landing is assured, reduce power to idle … Especially in heavy crosswinds, having little or no flap gives the wind less authority over the plane, which means I have more. Then it was important not to lose that asset by putting down too much (in a Cherokee) too early, so I kept that style of flying when I moved to the UK where my instructor was an airline jet jockey. What does your POH say--or is it silent on this point? Your brother “may” be right, but the premiss of “if you have them, use them” may not be the very best advise. Just when I couldn't stand it any more, my student finally raised the flaps. And I could argue that steep would be beyond my comfort level, with a few exceptions. If I had a 10 mile runway, it would not make any difference, full flaps would always be my number one choice. However, brakes wear obviously increased with the higher approach and landing speeds so eventually, the policy reverted to the original flaps 45 practice. Moved to 14A, Lake Norman Airpark, north of Charlotte,trees,and half the runway, learned very quickly to use full flaps, even a few kts can make a difference, squeeze as much lift as I can out of the wing, work the throttle more. This is from the short field landing distance performance chart, same standard-day, sea-level conditions, at maximum allowable gross weight. In DCS I am using the instant mission provided. Don't try to land the airplane before it's ready. Flaps are on the airplane to allow a slower airspeed at touchdown. After getting really good with “The Red 172” using full flaps (30 degrees), I took out “The Green 172”. Slips are appropriate in all planes. Don't try to climb with flaps down. set at between 25 and 40 degrees. The problem occurs in this situation because the natural tendency is to push forward on the yoke to maintain a reasonable takeoff attitude when the airplane (with full flaps) has more lift than it needs, wants to fly, and almost ends up standing on its nose--and its nose gear! I still prefer the Full Flap Landing. . How Wing Flaps Work. Reduce the throttle to around 1⁄3 and let the plane slow before drop-ping the flaps. If you stay on the rudder gusty crosswinds are not a big deal. I can now land successfully. The discussion in most of the thread was about personal preferences, and rationale behind them, for how much flap to use and under what circumstances. Add a comment below. Today it was 20deg flap. Both Flap 3 and Flap Full landings are approved by the manufacturer and the regulator. Always partial flaps : easier to control. For The Tiger that I fly a lot, flaps as needed but usually full flaps. I’ve only flown one single engine with 40 degrees flaps and didn’t have any problems with it. This was our final flight in a VFR/IFR recurrency program of some 33.7 flying hours to bring him back up to speed after a 15-year absence from the cockpit. Knowing how to use the tools available safely and properly will make you a better pilot. We had a major difference of opinion about using a 3 degree approach in a single prop plane!! Share your experience on any aspect of GA transportation flying, whether for business or pleasure. carb heat in hot till i touch the ground and goes off as soon as is safe to do so (cockpit load/tasks allow). Period. Instructor no.1 was a carb heat COLD on landing, and I obeyed. For any given type of flap installation, it also makes a difference how far you extend the flaps, depending on the situation you face for that takeoff or landing. Normally I like to use for a Cessna 150 , 20 degrees of flaps with 60 to 65 Knots on final, and increase it to 65 to 70 with stronger winds, except in short field landings when normally I bring the plane to 55 Knots with 40 degrees of flaps, but go around with maximum gross weight becomes very restrictive. It’s best to wait until you have the runway made to extend the last notch, however. I finally figured out that if I milked the flaps up, the airspeed indicator increased without losing altitude. PS . In the mid-seventies, as I approached 1000 hours single seat jet time and multiple carrier landings in an A-7E, I rented a 172 to take three college friends on a sight seeing tour of East Gainesville and the closed Pine Castle bombing range near Ocala.
