Once you feel comfortable flying in altitude hold, try out IRIS’ other flight
modes for GPS-positioned and autonomous flight.
Altitude Hold Mode
(ALT)
Allow IRIS’ autopilot to help you fly by engaging altitude hold mode (ALT). This
autopilot-assisted flight mode maintains altitude automatically. Set the left
stick to center, and IRIS will hover at the current altitude. Adjust altitude and
orientation with the left stick, and navigate with the right stick.
To select altitude hold mode, set the left mode switch to center and
the right switch to down (center/down).
