Chapter 190 - Flight Guidance (1st Update)
"Don't stop with your pole, the speed is up."
Instructor Chang found that Xu Qing had almost stopped the lever, and if he didn't intervene, the speed was too high, which would really lead to a hard warning.
Although he doesn't really care if there is a hard warning, even if the hard warning is too much, it doesn't matter if he is investigated, he is not afraid of any bureau inspection, but this manipulation is recorded on Xu Qing, the co-pilot does not have too many hard warnings, so he needs to accept the regulations of the investigation, but for the co-pilot who ranks in the forefront of the number of hard warnings, it will affect the transfer.
Therefore, Teacher Chang had to help Xu Qing control the number of hard warnings.
At this time, the throttle is left alone, the automatic throttle is turned on and remains at the take-off thrust.
Everyone knows that airplanes with autopilot systems will have guidance, usually there are cross guidance and eight-figure guidance, and the guidance of Boeing 737 is cross guidance. When Xu Qing was learning to fly abroad, the twin-engine aircraft in the commercial license stage had a simple autopilot system, and the plane was a bazi guide, and on the whole, the cross guide was relatively simpler and clearer.
The so-called cross guide is the horizontal and vertical red lines on the PFD, the horizontal line represents the required pitch attitude, and the vertical line is the roll attitude.
There will also be a white box on the PFD, and what the pilot has to do is to control the white box to cover the intersection of the horizontal line and the vertical line, and the more precise the set, the better, which is called following the guide.
To understand what is meant by following guidance, you need to understand the changes in flight guidance during the take-off phase.
737-700 and 737-800 in the take-off and run phase, the flight guide is to indicate the nose of the aircraft downward, and this is obviously wrong, so the SOP about the take-off run control guide mentions, do not follow the guidance during the take-off run!
After the aircraft lifts the wheels, the flight guide rises rapidly, usually the ascent rate is faster than the normal nose lift rate, that is, after the wheel is raised, it is very likely to lead to a large head-up rate warning, and too fast the lift wheel will also have the risk of wiping the tail. Xu Qing was precisely due to the experience of the previous car, after the starting wheel was too fast, overcorrected, slowed down excessively or even stopped the lever, this wrong maneuver directly led to the soaring speed.
At this time, the flight guide is on the top of the white box, that is, Xu Qing needs to continue to look up according to the guidance normally.
Instructor Chang put one hand on the accelerator, one hand held the steering lever, gently pulled back, the strength is just right, just to keep up with the guidance, impartial, this control has reached the point of detail, the speed also began to slowly decrease, and then stabilized in the normal range.
Xu Qing felt that Instructor Chang had moved the rod, and his face was also hot, knowing that he had a problem with the maneuvering again, and it was due to a relatively simple take-off. However, at this time, it has just taken off and is at a critical stage, and it is impossible to discuss it in detail, so it can only be postponed.
Here is also a reminder, after the take-off of the departure command, turn right track 234 is not to turn right as soon as the plane leaves the ground, but to keep the wing level to 400 feet, and then turn right track 234!
Therefore, below the altitude of 400 feet from the airport, do not press the heading selection button.
When taxiing on the ground, the ground control canceled Xu Qing's standard departure procedure, and at that time, Xu Qing canceled the preposition of horizontal navigation, that is, horizontal navigation will not automatically take effect after leaving the ground. After leaving the ground, the flight guide instructed the aircraft to keep the wings level until the pilot chose to roll after 400 feet.
helped Xu Qing bring a shot, and Instructor Chang saw that the deviation was almost repaired, so he stopped intervening. He is a relatively hands-off instructor, and he does not like to interfere with the maneuvering of young pilots unless necessary, and too much intervention is not conducive to the growth of pilots.
Fortunately, after he helped Xu Qing correct the deviation, Xu Qing followed the guidance very well, and there was no deviation after that.
Four hundred feet came in an instant, and the instructor first pressed the course to choose, first turned a right course 237, due to the influence of crosswinds, the course and the track were not consistent, and the instructor first pre-adjusted a course by feeling, and then refined the track.
"Blue 9271, continuous right turn to fly DADOL, the altitude corrected sea pressure 5100, corrected sea pressure 1019." Tower Command.
"Turn right and fly DADOL, the altitude is 5100, the sea pressure is corrected 1019, and the blue is 9271." The teacher often recites, and at this time he is in charge of the communication.
The instructor often mentions DADOL to the first line of the route page, presses the execution button, turns on the horizontal navigation, and turns right to fly directly to DADOL.
"Wait until you turn around and then speed up!" Teacher Chang said.
At this point, 1,000 feet have passed, and the instructor presses N1, and the throttle mode changes from preset to N1. After 1,500 feet, the acceleration altitude has been reached, but Chang Instructor considers that it is still in the turning stage, and although there are no regulations prohibiting acceleration at this time, most of it is still for the comfort of passengers. Accelerating at the turn time will cause passengers to feel a little oppressive and uncomfortable, and it is not too late to accelerate when they turn around.
When the plane finished turning, the instructor began to increase the speed of the flaps, until the flaps were closed, the transition lights were off, and after taking off, Xu Qing turned on the B channel for automatic driving. The aircraft passes 10,000 feet, turns off all lights, and adjusts to standard air pressure through the transition altitude.
At this time, the plane was basically stable, and the automatic driving had been connected, and Instructor Chang couldn't help but ridicule Xu Qing: "Is it difficult to take off?" Everyone has problems with landing, and there are problems with how you take off? Didn't you fly very sassy at that conference before, and the tricks of flying upside down were all figured out, why couldn't you even take off once? It's still not difficult to take off in a calm wind, and when it comes to the wind season, under strong crosswinds, and strong gusts, how can you fly? ”
The 2.19 incident raised Xu Qing too high, thus covering up many of Xu Qing's shortcomings, and the gap between the simulator and the real flight is very large, resulting in Xu Qing's current handling level is a little unworthy of his reputation.
With Xu Qing's current level of control, of course, it is no problem in the co-pilot level, but how can Xu Qing be limited to the co-pilot level because of his particularity, he needs to surpass the level of all co-pilot levels, which is in line with people's expectations of Xu Qing.
Teacher Chang has such an evaluation of Xu Qing's manipulation ability, which is more than conscious and not meticulous. Xu Qing knew what to do, but he didn't have enough finesse in manipulation.
Compared to today's take-off, Xu Qing can feel that the lifting wheel is faster, but the strength of the wheel release is too ruthless, but it is too much.
Just when the instructor wanted to mention a few more words, there was a sudden ding-dong sound in the cockpit, which was a prompt sound with ACARS information, and then a note came out of the printer.
Xu Qing tore off the note, which read: "CTUILSAvailable!" ”
