After landing short of the runway more than just a few times, I concentrated on determining why that was happening. How can I miss the whole darn runway. Well, I have seen that hundreds of times. The reason is rather interesting. Since a number of full scale pilots have all ready commented on this subject let me point out that if you are in the cockpit looking down at the beginning of the runway, you can clearly see where the runway starts. Well, in R/C the actual fact is that you do not know where the end of the runway is relative to the plane. Our telescopic vision allows us to determine distance up to about 17 feet. That is called Depth Perception. Just 17 feet. Look it up in Google. In average conditions you do not know where the plane is relative to the end of the runway until it touched down. By then it is too late to do anything about it. The plane is where it is. After I sorted all this I decided I wanted to have more control of where I touched down. I do that by selecting a favoring position at the field to stand at. I then attempt to touch down in front of me. That way I know where the plane is. At our field we have trees and building on each end of the field, and the only way to miss them, since there is no way to know where they are relative to my plane, is to have sky under the plane whenever possible. My final starts out very steep. I use elevator to shorten the approach and throttle to extend it. I make many elevator/throttle/rudder/aileron corrections to get it to touch down close to in front of me. Doing this in high gusting winds is a tremendous adrenalin rush. Most people seem to land the plane where ever the plane decides. They hit the trees or land short of the runway and do not know why. I hit a tree about every 5-6 years. I know why. Does this make sense to anyone?
