The radius of turn for a pull-down maneuver represents the distance from the center of the turn to the point where the aircraft completes a full turn while executing a downward pitch maneuver. It measures the curvature of the flight path during the maneuver, indicating how tightly the aircraft is turning while descending.
Where:
- is the radius of turn (in meters or feet),
- is the true airspeed of the aircraft (in meters per second or feet per second),
- is the acceleration due to gravity (approximately 9.81 m/s^2),
- is the load factor (dimensionless)
