"Now fly straight for a few minutes. Your right wing is low—bring it up. Your nose is too high. Now it is too low. Keep it so that the radiator cap is above the horizon. That's right."
So goes the business of instruction through the lessons on straight flying, gentle turns, misuse of controls, side-slipping, and approach, take-off, and landing. The trips should average thirty-five or forty minutes, long enough to teach the lesson, but not long enough to weary the pupil. Here at take-off and landing the pupil finds himself up against the most difficult part of his training. He has the problem of stopping a large machine weighing a ton or more, traveling at a landing speed of forty to fifty miles an hour, with the center of gravity just balanced over the under-carriage. An error in judgment will pile the machine up on its nose with a crashed propeller, and perhaps two broken wings and damaged under-carriage. Not a dangerous accident for the pilot, but very humiliating.
Army practice has shown that a pupil should have about sixty practice landings dual, that is to say, coached and helped by his instructor. By this time he has a total flying time of six to twelve hours. At this point, before he goes solo, the Gosport system provides that he shall be taken to a reasonably safe height for the practice of high maneuvers. At a height of say two thousand five hundred feet the instructor shows him how a stalled machine falls into a spin. The question of teaching higher maneuvers to civilian pilots is open to argument.
As soon as the instructor shuts off the engine the machine rapidly loses flying speed. It reaches a point where there is not enough air passing over the wing surfaces to support the plane in the air. Her nose begins to drop, and he pulls the stick back. The stick is full back, she stalls, topples over on her side, and plunges nose first. The instructor kicks on full rudder, and the world whirls below like a top, and the air whistles, swish, swish, swish, in the wires at every turn. Stick forward, opposite rudder, and she comes out so fast that your head swims. That is the spin.
"Now you try it," says the instructor. For there is nothing to a spin unless a machine does not come out of it—a rare thing if the plane is properly handled. The pupil is now ready to go solo, and for the first couple of hours' solo flying he does nothing but make circuits around the field, landing and taking off. Then his instructor takes him dual for forced-landing practice, business of getting down into a field within gliding range by gliding turns. Then the pupil tries it solo, throttling down for the practice, a most valuable experience which increases the confidence of the pilot. He learns to use his own judgment and to gauge height and ground distance as it appears from the air.
After three or four hours of solo time the pupil is scheduled for another demonstration of higher maneuvers, spinning and the stall turn. For the stall turn the pilot noses the machine down to get an air speed of seventy-five miles an hour. A little bank, stick back, she rears into the air with her nose to the sky and propeller roaring. Full rudder and throttle off. In silence she drops over on her side into the empty air; blue sky and green fields flash by in a whirl. She hangs on her back while the passengers strain against the safety belts, and then her nose plunges. The air shrieks in the wires as the ground comes up at terrific speed.
It is time for the pupil to go up for his solo spin under the plan adopted for army purposes. Up, up, up the pupil flies, three thousand feet, and the ground below looks soft and green. Would it be soft to hit in a spin from that height? It would not. Have people ever spun that far? he wonders. They have. Have machines ever failed to come out of a spin and killed the pilot? The answer is too obvious. With faith in nothing in particular, and with his mind made up that one can die but once in a spin, he stalls and spins her—and comes out. He is so surprised and exhilarated that he tries it again before he loses his nerve. Yet again. The pupil is a pilot, the air has no terrors, and he has learned the oldest truth of flying, that there is nothing to a spin unless you don't come out.
The natural result of training a pupil along those lines is that he graduates rapidly into a good stunting pilot. He realizes that he cannot tempt the devil at three hundred feet and hope to live, but he takes a good altitude, throws his machine upside down, and knows that, given enough air, he must come out. He does come out unless he loses complete control of his mind and body. With fifteen hours of solo flying the pupil has really become a pilot. He is beginning to show that he can control his machine. From then on it is a question of the polishing of the nice points, making his forced landings perfect, not side-slipping a foot on his vertical banks, and coming out of spin so that he always faces the airdrome—all of which distinguish the good pilot from the poor pilot.
