Landing is the most difficult part of aviation to master. A great many of the accidents occur because the aviator has made a poor contact with the ground. In fact, in the early days of aviation most of the accidents occurred near the ground, and this led people to speculate on the peculiar action of the lower air currents. These, in reality, had little to do with it. The cause lay in the inability of the pilots to know how to make proper contacts and to appreciate the fact which we now know to be a fundamental principle, that the engine should be shut off before a machine catches the air and volplanes down against the wind. There are exceptions to this rule, but not for a beginner. Sometimes it is necessary for the pilot to descend against a strong wind. In order to maintain the required speed the motor must be left partially turned on. Generally it is most important to turn off the motor, because if the landing is made with the wind, even in the gentlest breeze, the aeroplane, on account of the speed of the tail wind, is likely to turn a somersault and be completely smashed up. Even then another manoeuvre has to be mastered. Just before alighting the pilot must make a quick upward turn, so that at the moment of contact the machine may be travelling parallel with the ground. Formerly the importance of this little upward turn of the rudder was not fully appreciated by aviators, and many a machine was wrecked by a sudden hard compact with the earth. When the "moniteur" sees that his pupil has acquired the knack of making a landing he passes on to the all-important manoeuvre of volplaning, and the dreaded "perte de vitesse" is tackled. Lastly, but not least, comes the "virage"—turn, or bank, as we say in English. These rudimentary principles are all that are required of the élève before he may go up alone, or be "lâché." During this phase of my instruction it was repeatedly impressed upon me that, if anything ever happened to me when I was in the air and I did not immediately realize what to do, I was to let go of the controls, turn off the motor, and let the machine take charge of itself. The modern aeroplane is naturally so stable that, if not interfered with, it will always attempt to right itself before the dreaded "vrille" occurs, and fall "en feuille morte." Like a leaf dropping in an autumn breeze is what this means, and no other words explain the meaning better.
