What is the detailed process of the plane from before takeoff to takeoff?

The first step is to check the plane. When the captain arrives, he should check the checklist provided by the ground crew to see if all the parts to be checked have been checked. Then the captain has to walk around the plane twice by himself, check some key parts by himself, and then sign the handover form, so that the plane is officially under the command of the captain.

Turn on the main power switch. If you don't want to lose the power of the FMC flight management computer, turn the power switch to GND ground or turn on the APU auxiliary power supply device for power supply.

Turn on the navigation lights and flashlights of the plane. You can't turn on the landing light, it will burn.

First, turn on inertial navigation calibration. The switch of this thing is overhead, with a * * * and three switches. The whole calibration process takes about 15 minutes. After calibration, the current position of the aircraft will be displayed on FMC.

Turn on the radio and listen to the weather forecast. At the end of the forecast is a message XX, which is very important to remember.

Adjust the release frequency and make a good flight plan report. Basically, it is: XX Airlines flight XXXX, XXX to XXX route, planned altitude FLXXX, received the message XX (reported the number you just heard), requesting approval.

After receiving the clearance, he will check his list to see if there is such a thing. If there is, he will repeat what the captain said just now. When the captain hears it, he will repeat it. This is a flight permit, but it is not a take-off permit.

Set FMC, enter departure airport, destination airport, navigation point, planned cruising altitude and planned cruising speed, and then cross-check whether it is correct, because some navigation points have the same code, but the latitude and longitude are different by 108,000 miles. Some airlines will store Chang Fei's route in FMC and just call it out directly, but it still needs to be cross-checked. ?

Turn on the air conditioner and lights in the engine room, and let the lovely flight attendant MM come up to prepare for the flight. And check all the instruments by yourself, such as the amount of oil, open the cargo door and start loading luggage. Passengers will begin to register later. Welcome as usual: Dear friends, I am the captain of this flight. Welcome to fly XX Airlines from XX to XX. ? After the luggage is packed and the passengers are packed, close the hatch. Check the weight of the aircraft and adjust the trim wheel.

FMC can calculate the speed required for taking off today and set AP autopilot. Two crew members cross-checked the equipment settings. There is a list. The co-pilot is responsible for watching, and the captain is responsible for checking. After the inspection, contact the ground, request launch, and prepare for takeoff. The ground will ask if the trailer is in place. Then the ground will answer and agree to launch, with the nose facing X (east, west, north and south). At this time, the big trailer began to slowly push the plane out.

Push it out, start to connect the oil circuit when it is in place, open the air extractor, start the left engine first, and then start the right engine. Contact the ground and request to start taxiing. The ground will tell you which taxiway to pass and which runway to reach, repeat this sentence, then release the brake, step on the accelerator and start taxiing. ? The ground will observe the taxiing situation of the plane, and inform the captain to contact the tower instead when it is almost done.

The captain will say: flight XX, request to take off at runway XX. The tower will answer: XX flight, runway leaving XX, etc. The captain will taxi the plane to the taxiway at the end of the runway and wait. You can't enter the runway, otherwise it will be a serious accident, or at least a sign of a serious accident. At this time, the two crew members conducted the last cross-check before take-off. After the tower confirms that there is no aircraft taking off and landing on the runway, it will contact the captain: flight XXX, which can take off on the runway XX, with the wind speed XX knots/direction XX, and correct the field pressure XXXX (if the atmospheric pressure is not corrected, the altimeter of the aircraft will be inaccurate, for example, when you take off in Tibet, the altimeter shows how many kilometers your altitude is), and use XXXX to leave (this is a standard departure procedure called SID).

The captain repeated this sentence, then turned on the landing light, put the flap at five degrees, slowly pushed the throttle, and the plane began to accelerate. According to the setting of FMC, the co-pilot should remind the captain that the plane has taken off. ? After leaving the ground, close the landing gear and the tower will contact the captain. Please contact and leave. Goodbye. The captain repeats, then contact the departure, and the departure will tell the captain how high to continue climbing. After more than 400 feet, the captain opened the AP and put away the flaps, and the plane began to fly automatically. At this time, the plane will lower its head and return to the normal climbing height. At this time, the captain is no different from us, just sitting and watching the instrument.
