The “Horizontal Displacement of Turn Needle” in aircraft design refers to the angular displacement of the turn needle from its centered or neutral position on the Turn and Slip Indicator instrument. It is a measure of how far the turn needle has moved to the left or right from its central point, and it indicates the rate of turn of the aircraft.
The formula for calculating the angular displacement of the turn needle is as follows:
- Horizontal Displacement of Turn Needle is the angular displacement of the turn needle in degrees.
- Rate of Turn is the rate at which the aircraft is turning, typically measured in degrees per second (°/s).
- Time is the duration over which the displacement occurs, typically measured in seconds.
