hi pilots, during long time, i used to do hard landing, bounce, and often safe go around. recently figured out what was wrong in my landing techniques.
At runway threshold, - keep ur speed to 1.2 or 1.3 stall speed and then reduce the thrust to Zero(idle). - then enter the runway in a rectangle formed by the runway width and 1 or 2 wingspan - once above the runway, maintain a step flight, 1 or 2 ft above ground and align on the center line - then u can be attempted to touch the ground but dont let the airplane dive (my mistake) - maintain the step flight with smooth pitch up effort until the airplane stall, keep an eye on the side to assess the ur height (loss of front visibility due to high pitch up) and minimize it. - at stall, keep nose up, 1 ft above or less, let the plane touch alone the ground. there wont be any bounce as the speed is too low and no hard landing as the ground is very close. At that moment, the airplane seems to have a very high pitch angle so some can fear to have a tail strike, but it is just an illusion.
my big mistake is that i was trying to shorten the landing phase to touch the ground too earlier, let the plane fly above the runway until it is too slow to fly.
Hi Serge, Just curious, do you not use your "V" speeds to determine your approach, pattern, final and flair speeds? It has been years since my schooling, so my ability to remember the exact sequencing is subject to question, but the plane I learned on (1969 C150) my pattern and final descent speed was 75 or 70 knots. 40° flaps was not used until turning final. Power was at idle then, and your rate of descent was whatever was necessary to maintain your airspeed at that 70 knots. When the runway stopped looking like a rectangle, and started looking flat, you started your flair. Usually you could feel the aircraft approaching stall, and about the time your stall horn started to squawk, your rear gear were just kissing the pavement. Flair and touchdown are difficult (for me) to explain what all is happening, since so much is happening all at once, and I am drawing on memories that are a few decades old. But the picture in my mind of what the runway looks like with your plane sitting on it was my mental visual reference to flair shortly BEFORE it looked like that. Once you have that reference firmly affixed in your mind, it was fairly easy to "grease" your landings.
Now, flight sim landings? With a DC-3? That's a whole 'nuther story! 😄😄😄
Hi Iron, yep there is constant speed to maintain from last turn to the flare. after last turn, flaps is set to all extended (and ldg gear extended if applicable), the airplane should be maintained in the descent slope with a constant speed (70 kt on my airplane). at flare (1 or 2 wingspan height), thrust is set to all reduced and the airplane trajectory is becoming a step flight with small height above runway. during this step flight, speed goes on decreasing so the angle of attack is constantly increased to maintain the step trajectory. Most of my issues at landing occurred during flare: i didnt wait for the speed to decrease enough, as soon as the airplane was in almost 0 vertical speed, i was attempted to touch the runway but most of the time the A/C speed is often still too high. so even if VS is almost negligible, the airplane touches the runway with lot of energy due to horizontal speed, that can create bounce in grass runway, or worst, the nose wheel can touch before main gear causing the propeller to hit the runway (instructor takes over before that...fortunately).
u can reproduce this behavior in flightsim, by setting all parameters to realistic and detect all crash conditions. it makes flying more difficult but it is good way to train for all future pilots in here:)
devon: How is everybody? Apologies for not updating server yet. Will get done soon. Gonna have to find some time to fly myself at some point. Lots going on between school work and planning vacation and flights for next year.
