What flight data need to be measured in flight?

The most basic flight data to be measured when an aircraft flies are altitude (air pressure), airspeed, heading and attitude, including horizontal slope and pitch, vertical speed and sideslip. As well as the engine speed, fuel quantity and oil pressure in the aircraft. Airspeed tube and angle of attack sensor: measure the angle of attack of aircraft flight. Altimeter: It measures the absolute height of the plane to the ground.

Extended data:

The takeoff of an airplane depends on the lift generated by the relative movement with the air, and the lift depends on the relative speed between the airplane and the air, not the relative speed between the airplane and the ground. If you take off against the wind, the taxiing speed of the plane is opposite to the wind speed, and the relative speed between the plane and the air is equal to the sum of the two. At this time, the aircraft can get the lift needed to get off the ground at a small taxi speed.

Therefore, compared with windless takeoff, the distance required for taking off against the wind will be shorter. On the contrary, if you take off with the wind, the plane will have to reach a great taxiing speed to get the lift needed to get off the ground, and the taxiing distance is also relatively long.
