The ground sensor on the eBee RTK was unable to de-
tect the proximity of the ground during a Linear land-
ing procedure. This may be due to an obstruction in
the sensor, low ambient light or low contrast in the
environment⁶¹.
Security action: The drone continues the Linear
landing procedure but will initiate its final brake at
an estimated altitude of 20 m instead of 3 m (assum-
ing the Linear landing location is at the same altitude
at the Take-off location), resulting in decreased pre-
cision in the landing location.
User action: Be ready for the drone to overshoot
its planning Linear landing location by preparing a
larger obstacle-free zone around the location.
There are no approach sectors available against the
direction of the wind. The eBee RTK has calculated a
Linear landing approach direction in the direction of
the wind.
Security action: The eBee RTK continues normal
flight.
User action: Add a new approach sector against the
direction of the wind, if possible, abort the landing
and try landing again. If not, be ready for the eBee RTK
to overshoot its planning Linear landing location by
preparing a larger obstacle-free zone around the lo-
cation.
