Step 4 – QBase nal check
Obstacle clearance in reality
• No obstacle within a radius of 20 m around Home Waypoint
• Re-/transition, descent circle, ight paths: altitude 20 m higher than obstacles
UAV heading
• Ensure the heading of the displayed UAV corresponds to the direction of the UAV on the ground
• Do not y if the heading on the ground is not correct: critical deviation ≥ 10°
Wind direction
• Re-/transition is set against the wind direction!
• Retransition with tailwind: per 1m/s tailwind ~ 20 meter deviation
• Windcheck in the immediate surrounding
• Do not take-off in a wind sheltered area (lee) as turbulances may occur

Make sure the home waypoint in QBase
is adjusted to the real take-off position
.
Step 6 – Preight check
The UAV will self-check and initialize the attitude and position algorithms.
After the Preight Check it is recommended to wait at least 30 seconds before you start your mission so that GPS data on the
ground will be logged prior to ight. This enables a better PPK convergence in the post process.
