Chapter 33 Take-off stall
The next day's flight schedule started at one o'clock, and it was the end of summer, and the temperature was strangely high, especially in the cement, asphalt and asphalt places of the airport, which were like steamers, and it was so hot and stuffy.
Xu Wei did not let the instructor call this time, but spontaneously took the dispatch order in advance, took the key box, and went to the tarmac alone to do the pre-flight inspection. Xu Wei was already familiar with the first few steps, that is, he had not studied to inspect fuel and lubricants, but in the morning he went to do a pre-flight inspection with Dong Shiqi, and his instructor was natecherry, the instructor who gave them ground classes. When teaching Dong Shiqi how to do a pre-flight inspection, he not only had to make sure that Dong Shiqi knew how to do it, but also let him know why he did it, which was much more detailed than Xu Wei's instructor, and Xu Wei, who was listening, understood it three or four percent. However, fortunately, Xu Wei understood how to check the fuel, which was exactly what Xu Wei needed.
This time, Xu Weifei's plane is the same as Dong Shiqi's, Cessna 812DC, Xu Wei can repeat the work, there is no difficulty at all, in fact, most of the inspection actions Xu Wei also knows what is qualified, as for why he is qualified, he does not know.
When Xu Wei finished checking the lubricating oil, the instructor was late, and he shouted at the top of his throat from a distance: "What'supman?" Xu Wei first tightened the lid of the lubricating oil, and after confirming that it was safe enough, he replied: "Perfect!" At this time, the instructor was already approaching, smiling and putting the papers into the cockpit, about to go to check the fuel. Xu Wei hurriedly said, "fullfuelsir." The instructor was stunned for a moment, stopped what he was doing, stared at Xu Wei, and said in disbelief: "You knowhowtocheckfuel?diditeachyou?" The instructor himself was confused, he remembered that he shouldn't have taught Xu Wei how to check oil. Xu Wei was so stinky in his heart that he grinned, and said proudly: "nateilearntfromnatesecretly" The instructor shrugged his eyebrows, quite surprised, and then seemed to be displeased, and grimaced. “iamyourinstructorstudyfrommebutsmartguy.” Xu Wei couldn't be happy in his heart, the atmosphere at the beginning of the flight was very good, which was very beneficial to the atmosphere of the cockpit behind.
The C812DC also belongs to the Cessna series, but instead of the C152 that flew before, it is C150 white paint, and the appearance is similar, but it looks a little smaller. The look is a lot newer, the GPS is bound to the steering wheel, and the style is also more advanced, and the dashboard is also almost completely new. People always like new things, especially airplanes, and new airplanes mean safer, which is a rather naïve idea, but that's what Xu Wei felt at the time.
Xu Wei advanced into the cockpit, waited for the instructor to go in, and began to make his own checklist, occasionally made mistakes, the instructor reminded from the side, and then the radio talk, taxi, smoothly entered the runway.
This take-off is still done by Xu Wei, the new flight maneuver, the general instructor will be the student after two or three demonstrations, this is the American tradition, I am very willing to let the students go, do not shrink back, it is impossible to learn to fly well if you are afraid.
Xu Wei was not so nervous in his heart, he stepped on the accelerator, controlled the direction, everything went quite perfectly, and there was almost no deviation along the middle line. Xu Wei was excited, his progress was too great, he would definitely be praised this time, and he felt a little excited when he thought about it.
The plane reached the speed of the tie rod smoothly, and the plane raised its head smoothly without any abnormal circumstances.
The instructor sat leisurely on the right seat, and suddenly found something, his body suddenly tensed, sat up straight, and reminded Xu Wei loudly: "watchoutspeed." Xu Wei subconsciously looked at the airspeed meter, and suddenly broke out in a cold sweat, the instrument showed that the airspeed was only 45 knots, and it was about to stall, but the aircraft lift gauge showed that the ascent rate of the plane was very small, and there was almost no rise. Xu Wei instinctively wanted to pull the plate to increase the rising speed, but he regretted it as soon as he moved his hand, and the airspeed of this pull was reduced again, and the stall alarm suddenly sounded. Xu Wei was so frightened that he didn't know what to do, the most direct way to correct the stall was to press down on the nose, but they had just left the ground, and the head of the press might hit the runway, Xu Wei didn't know what to do for a while. At the difficult time, the instructor took over the plane, and the situation at that time was beyond Xu Wei's ability, and the instructor had to take action. Xu Wei immediately let go, so as not to interfere with the instructor's operation. The instructor immediately pressed down on the nose of the plane, but he grasped the degree well, broke the moment of stall, stopped the momentum of downward pressure, and the plane did not produce a negative descent rate but flew close to the runway in an almost level flight attitude.
The airspeed increases at a faster rate until it reaches 60 knots, and then the steering wheel is pulled back, giving the plane an upward momentum, but the climb speed hovers between 50 and 55 knots, like walking on thin ice. Xu Wei's heart seemed to be tightened, staring at the airspeed and not daring to move away in the slightest. The plane climbed at a slow speed, the higher the altitude, the airspeed, and the rate of climb were gradually improving, and Xu Wei secretly breathed a sigh of relief.
