How to grasp the direction of the plane flying at an altitude of 10,000 meters?

The main function of the magnetic heading instrument is to measure the angle of the current north and south poles of the earth's magnetic field and its own heading, so that it can be combined with the heading of the aircraft itself to judge the trajectory of the aircraft after take-off relative to the take-off airport. Together, the plane can fly in a specific direction, such as heading 180, which is due south. However, there is a flaw in this way of navigation, that is, with the increase of time, there is always an error in the integral, and the error is constantly expanding, so the error correction needs to be given by the outside world at different stages.

During the whole long-distance flight, the aircraft mainly relies on its own navigation system for the identification and navigation of the course. Inertial navigation mainly uses gyroscopes to measure the acceleration and speed of the aircraft body in all directions in the air coordinate system in real time, and of course, its own course, relying on these measurements under the action of the timer, you can carry out manual or computer-intervened integration operations, so that you can draw the aircraft's own navigation trajectory. The most critical gyroscope in the inertial navigation system has also developed different types of products, from the earliest mechanical inertial navigation, to the later laser inertial navigation, optical fiber inertial navigation, and composite strapdown inertial navigation, etc., the measurement accuracy is getting higher and higher, so as to improve the measurement accuracy of the inertial navigation system from the source.

In terms of direction, the compass and compass can all be done in ancient times. Modern science and technology are so developed, airplanes have flight lanes, positioning facilities, such as even according to the earth's magnetic field for guidance, these things can basically solve the problem in all directions.

The plane flew at an altitude of 10,000 meters. Airplanes have routes. Controlled by radar on the ground. The plane is in flight. There is a dirty row table. It shows the route.

GPS satellite navigation, different from the traditional compass. The traditional compass relies on the earth's magnetic field to determine the direction, while the GPS relies on the movement of the aircraft relative to the coordinates of the reference satellite to calculate the heading of the aircraft.

Relying on the GPS system, the aircraft can get its own air coordinates, speed and altitude values from more than 3 positioning satellites in real time, and this positioning accuracy reaches the meter level, which is actually enough for civilian use.

There is not much difference between the 10,000-meter altitude and the ground, one is two-dimensional, the other is three-dimensional, but there is one more height value, and there is no difference in direction. Whether the submarine is underwater or the aircraft is at high altitude, the altitude can be accurately measured.

An airplane is a very sophisticated machine, whether it is a passenger plane or a transport aircraft, or a fighter jet, it has a navigation system to ensure that the flight direction is correct and avoid being like a headless fly.

The roommate's GPS on the plane can be based on this to grasp the direction.

I heard a civil aviation friend say that when you go up and down, you will operate it, and it will fly automatically when you go to the sky.

The direction is by the tail rudder and the wind deflector on the monowing, and the height is by speed.

We all know that planes generally fly at an altitude of 10,000 meters, and sometimes they fly higher than fighter planes, so why do planes have to fly in such a hail sky?

At present, fixed-wing aircraft are generally controlled by the wing and the upper aileron, the horizontal stabilizer and the horizontal tail above, the vertical stabilizer and the upper tail rudder to control the direction, the aileron is responsible for rolling, the horizontal tail is responsible for pitching, and the vertical tail is responsible for the offset of the horizontal direction.

After take-off and autopilot, the flight computer will process the data obtained by the sensors and control the movement of the aileron and tail to control the direction and altitude of the flight, of course, provided that there is a certain speed.
