Chapter 7: Take off!
Xu Wei found that the instructor had set the radio frequency to 121. 6. The instructor also explained that this frequency is the ground frequency of athens_airport, which is the so-called "ground", which Xu Wei will often use in the future, and when the plane taxied on the ground, it was necessary to obtain permission from the ground control.
The instructor adjusted the frequency and began to contact the ground.
“athens_ground,c9988,east_ramp,ready_to_taxi。” Meaning athens ground, the Cessna 9988 is on the east apron and is ready to taxi.
After waiting for a moment, the sound of ground control came from the headphones.
"C9988, clear_to_runway27_via_taxiwaya_cross_runway20" This is permission given by ground control, meaning that Cessna 9988 allows access to runway 27 and crossing runway 20 on the way through taxiway A.
With permission, the instructor slowly increased the horsepower and drove the plane slowly off the runway. The nose of the plane turned into the taxiway, taxied along the center line of the taxiway, and as the scenery in front of the cockpit changed, several people were photocopied, it was a group of young figures, confused and determined about the future, they chose this profession for money? For status? It's still not for anything, just like Xu Wei, he entered this line of work in a daze. Far away, Xu Wei could still feel their eager gaze, that kind of longing for the future.
Before entering the runway, a pre-takeoff inspection is also required, mainly to test the performance of the engine. After confirming that everything is in order, the aircraft cannot enter the runway and needs to stop before the holding_line and cannot cross. Before that, you need to contact the tower and get permission from the tower.
The frequency of the tower control is not the same as that of the ground control, and the frequency of the athens tower is 126. 8。 After the instructor confirms that everything is safe and meets the take-off requirements, he asks the tower for permission to take off.
“athens_tower,c9988,holding_short,runway27,ready_for_departure。” Xu Wei carefully distinguishes each word, hoping to be more familiar with the sentence structure of the land and air dialogue, the radio communication format of civil aviation is relatively fixed, both inside and outside, Xu Wei needs to remember when to do what to say, how to answer.
A moment later, the tower replied. “c9988,holding_short,traffic_on_final。” The instructor turned his head, through the window, searching for something in the sky at the end of the runway, and suddenly seemed to find something, pointed to a certain location, and motioned to Xu Wei to take a look, Xu Wei looked at it, it seemed to be a black spot, it seemed to be a bird, and closer, what kind of bird was it, it was obviously a plane about to land.
The instructor has already begun to reply to the tower. “holding_short,c9988,tower,traffic_in_sight。” Most of the pilots have to repeat the controller's instructions to confirm that the pilot has received the instructions correctly. The instructor's reply was that C9988 was waiting, and that the plane had been seen.
The plane in the distance slowly approached, and Xu Wei could finally tell that it was a DA20, pure white paint, with a streamlined fuselage, like an elegant white swan. The plane gradually approached the runway, the altitude decreased, and at the moment close to the ground, the nose of the plane was slightly raised, and it began to glide. However, at the moment before the grounding, the pilot seemed to be nervous, pulled down the lever excessively, the nose of the plane rose too much, the drag increased sharply, the airspeed dropped too fast, and it slammed into the runway all at once.
The instructor also observed the whole process of the plane's landing, and made a smack sound at the moment when the plane landed again.
“bad_flare。” It was not good to glide, and the instructor immediately used this landing as a teaching material to give Xu Wei on-site guidance.
“this_pilot_must_pull_too_much_in_the_end_of_flare。 Xu Wei listened to the instructor's explanation with relish, and an extremely important part of flying is landing, which is also one of the difficulties of flight training. In this era, the safety of civil airliners has reached a certain height, but the danger has not been eliminated, take-off, landing is still accident-prone period, especially landing, therefore, the aviation school attaches great importance to the landing ability of the college, such as crosswind landing, emergency landing with flameout and so on.
Xu Wei heard half of it, still savoring, and was suddenly interrupted by the sound of the tower.
“c9988,turn_right_on_course_clear_for_takeoff。“ The instructor quickly repeated the permission, and translated into Chinese is C9988 to turn left into the course and allow takeoff.
The instructor stopped his previous lecture for a while, let go of the foot brake, added some throttle appropriately, and aligned the runway center line while turning. When it was completely straight, what was shown in front of Xu Wei was a wide runway that was more than a kilometer long, and the picture at this time was as if he was in the scene of a TV series, which seemed a little unreal. The reality did not give Xu Wei too much time to sigh, the instructor directly filled the throttle, the plane gradually accelerated, verified whether the index of each instrument was abnormal, and then focused on the airspeed meter.
Each different type of aircraft has a different head-up speed, and the C9988 belongs to the Cessna 152, which has a head-up speed of about 60 knots. As the airspeed accelerated, the bumps in the fuselage became more and more obvious, and the scenery on both sides was rapidly retreating, which made Xu Wei feel fearful in his heart. “
