During the Landing Sequence

The following should be monitored during the landing sequence.

Depending on the mission plan or flight mode, the Evo can perform a straight-line, loiter-down, or manual landing. When the Evo is executing a landing sequence, it will significantly lower the altitude. Special care must be taken during the descent stage to avoid collision with obstacles. When a collision seems imminent, the pilot must take control of the drone and increase altitude either by switching to a manual control mode and pulling the pitch stick down (nose up) or by repositioning the vehicle and increasing altitude. In such an occurrence, it is advised to either change the mission plan and execute an RTL after the change or land the vehicle manually.

Unstable Descent

Operator Action: None

If the vehicle becomes unstable during landing, the landing speed, as indicated in the Safety features, is likely set too high.

No Auto Disarm After Touchdown

Operator Action: DISARM (Emergency Action -> SHUTDOWN)

The DeltaQuad Evo should disarm automatically 5 to 10 seconds after touchdown. If the vehicle does not disarm automatically, the disarm command (Shutdown) should be sent. This command can be sent by selecting Emergency Actions - Shutdown. The reason for this could be related to landing on a significantly uneven surface or slope. It can also indicate that the sensors need calibration.

Landing gear legs do not deploy

Operator Action: None or reposition above soft ground

If one of the landing gear legs does not deploy during descent, do not interfere, as the DeltaQuad Evo is designed to balance itself on the ground even with only three legs deployed.

If two legs or more do not deploy during descent, position the vehicle above soft ground (NUDGING), such as grass, and avoid hard ground, such as concrete.

After an incident or crash wait 10 minutes as the battery may become unstable. Take pictures of the vehicle from every direction. Try to document the crash and crash site as thoroughly as possible.
