Flight Modes

This section describes the location and function of the flight mode controls on the hand controllers.

Flight Modes and the IF800

Mode	Description
Loiter (A)	Loiter mode is optimized for precise movements and to hold station in latitude, longitude, altitude, and heading. If the aircraft is moving and you release the joystick the aircraft will stop and hold station at the location the aircraft was at when you centered the joystick.
Position Hold (B)	Position Hold mode is optimized for larger movements compared with Loiter. The aircraft will hold station in latitude, longitude, altitude, and heading. If the aircraft is moving and you release the joystick the aircraft will decelerate and hold station at the location when the aircraft stops moving.
Return to Launch (RTL)	This mode is recommended for normal landings and for landing after an autonomous mission. When activated, the aircraft automatically returns to its Launch position and lands. The Launch position is the original takeoff location of the aircraft.

WARNING: The IF800 Tomcat automatically returns to the launch site as a failsafe when the battery voltage gets too low to continue flight; visually monitor the battery level in IGC and replace the battery conservatively to mitigate risk.
