Advantages and disadvantages of the secret evaluation draft of night flight and suggestions

Advantages, disadvantages and suggestions of the night flight secret review draft are as follows:

Advantages and disadvantages of night flight secret review: clear thinking and strong logic.

Definition of precision approach: an instrument approach procedure that provides precise azimuth and glide guidance by instrument landing system or precision approach radar. In contrast, the imprecise method only provides horizontal guidance. (In some textbooks, azimuth guidance is also called horizontal guidance, and gliding guidance is also called vertical guidance. ) The common equipment that can provide accurate approach is the Instrument Landing System (ILS).

Microwave landing system (MLS, mainly in Europe), precision approach radar, etc. According to the definition of precision approach, these devices should aim at the extension line of the runway center line in the direction to provide accurate azimuth information when the aircraft performs maneuvers such as descent, deceleration or track correction. In order to ensure that the aircraft does not deviate from the glide path on the vertical section (height), accurate glide information is provided.

Let's take the instrument landing system as an example: ILS system is mainly composed of two subsystems, one providing horizontal guidance (LOC) and the other providing vertical guidance. Through the cooperation of the two subsystems, the plane landed on the runway accurately. This guidance is obtained by comparing the modulation depth of the radio signal received by the ILS receiver on the aircraft.

Winged flight, known as the "king of extreme sports", can reach 200 kilometers per hour, which is the closest to bird flight among all known sports. Recently, the 9th WWL Winged Flying World Championship was held in Tianmenshan, Zhangjiajie, Hunan. 1 1 6 winged flight athletes from all over the world compete at high speed in the mountains.
