A vertical takeoff or landing consumes significantly more energy than a fixed-wing flight. For maximum efficiency, an altitude between 25 and 35 meters is recommended for landing.
At every stage in the fixed wing portion of the flight, a vertical separation of at least 25 meters above the highest obstacle must be maintained.
When planning a landing either in mission, or quick-takeoff modes, the altitude must be set at least 25m above obstacles such as trees that may potentially fall in the flight path of the vehicle.
The altitude of the "Planned Home Position" defines the expected touch-down altitude.
The back transition from fixed-wing flight (Aerodynamic mode) to multirotor flight (Hover mode) is performed at the altitude set in the "Orbit point" of the Mission End Action command.
Most wind forecasts are based on ground-level wind. Even 10 meters above the ground the wind can be significantly stronger.
During the transition phase of the "Transition Direction" item, the vehicle has limited navigational abilities and could drift from its intended direction. The transition should therefore always be performed at an altitude where it is safe for the vehicle to perform the transition in any direction.
