senseFly eBee X - Page 70

Using your eBee X
A typical Steep landing follows these steps:
1. The eBee X flies towards Home (defined by the user within eMotion; default
altitude is 75 m (250 ft) above the landing altitude). The drone will fly to
Home at whichever altitude is the highest; its current altitude or Home’s
altitude. It will climb in a spiral first if needed.
2. Once Home is reached the drone circles the waypoint then either climbs or
descends to the altitude at which it will begin its downwind landing leg.
This altitude depends on the difference in altitude between Home and the
landing spot:
• If Home is more than 75 m (250 ft) above the landing spot, the drone
will descend to 75 m (250 ft) before starting the downwind leg.
• If Home is between 50 m (160 ft) 75 m (250 ft) above the landing spot,
the drone will start the downwind leg at that altitude.
• If Home is less than 50 m (160 ft) above the landing spot, the drone
will climb to 50 m (160 ft) above the landing spot before starting the
downwind leg.
3. The drone circles to estimate the wind speed and direction. An approach
direction is then calculated, and the drone chooses from which of the two
possible directions (defined by the landing strip) it will land.
4. The drone flies downwind against the approach direction. After flying for
a sufficient distance it turns around to align itself with the approach direc-
tion.
5. The drone uses reverse thrust to enter a steep descent at an angle of ap-
proximately 35°until it reaches the ground.
• Ensure that the ground is flat and at the same altitude as the landing spot
for a distance of at least 30 m (98 ft) ahead of the landing spot in both ap-
proach directions.
• Ensure that there are no obstacles within 40 m (131 ft) of the landing spot.
