I believe Litchi needs 'x' altitude before you can start a mission. Think I saw that in the manual.
Edit. You can start from ground too, I stand corrected.
Flying a Mission
Prior to flying a mission, tap the Camera Settings icon at the right of the Litchi display and
confirm that your camera modes are as desired. Make certain there are no obstacles
between the aircraft’s initial position and the first waypoint. For Phantom 3 and Inspire, the
flight mode switch on the controller must be in the F position (the “Function” mode) for
Litchi missions to proceed autonomously. For the Phantom 4 the switch remains in the “P”
position for autonomous flight. You may take off manually if you wish (with the flight mode
switch in the P position). With your aircraft in a hover, change the Flight Mode Switch to the
F mode (Phantom 3 & Inspire only) and then touch the "Start/Pause" button located in the
left button bar on the Litchi display. You may also initiate your mission from the ground by
placing the flight mode switch in the F mode (Phantom 3 & Inspire) and then touching the
“Start/Pause” button.
If you receive a “Requirements Not Met” error message, confirm that your controller is
definitely in the F mode (Phantom 3 & Inspire only). If you are initiating a mission from a
hover, try climbing to a higher altitude or fly a little further from the takeoff point and re-try
the Start/Pause button. When prompted, confirm your intent to begin the mission and your
aircraft will initially climb to 6 meters (about 20 ft.) and then proceed autonomously to the
first waypoint in a direct path, where the mission will commence.
