What is a Tick Indicator?

Attitude indicator is a device used to indicate the direction and position of the aircraft relative to the horizon during the flight of the aircraft. Attitude vehicles are also known as gyroscopic horizons or artificial horizons. The attitude indicator can indicate the aircraft's pitch (including forward and backward tilt) and tilt (including lateral tilt) status, and the aircraft's main instrument flying under different weather conditions.

(1) "Miniature plane" represents a point on the horizontal line between the wing and nose of the aircraft.

(2) The center horizontal line, a horizontal line in the center of the display, divides the display into two parts. The upper half is blue, representing the sky; the lower half is brown, representing the earth.

(3) A scale indicating the inclination angle. The scale is distributed along the edge of the display. On a typical display, the inclination angle scale starts from 0 ° and has 10 ° and 20 ° scale levels. In addition, there are also 30 °, 60 ° and 90 ° grades.

Attitude indicator uses its miniature airplane and horizon to show the attitude of the aircraft, miniature airplane and horizon

(1) The attitude of the aircraft in terms of pitch and tilt. The principle of instruction is: the small plane is fixed and the horizon moves up and down. The ball of the skid gauge is still used as a reference for skid, as shown in Figure 5-30. ^[2]

(2) Landing of the aircraft. The pointer is located on the left side of the meter to indicate the direction of the glide.

(3) Turns and sideslips of the aircraft. This is indicated by the commonly used turn-slip gauge, which is located below the integrated indicator and includes a small ball and a pointer. ^[2]

(4) Aircraft pitch and flight direction. This is indicated by a horizontal and vertical pointer. In the case of pilots taking off and navigating with instruments, using "Instrument Automatic Landing Approach System" for approach and landing, and "Ground Control Approaching System" for approach flight, etc., the heading can be maintained by vertical pointers. When maneuvering and low-altitude bombing, these two horizontal and vertical pointers can also be used to indicate flight conditions. ^[2]
