Drone exam · Ground-risk mitigation

A town square is nearly empty during setup but will fill before the planned final flight. Why should the morning site survey not be reused unchanged?

Answer

Reassess the expected number, density, movement, entrances, barriers, and emergency routes for the actual flight time and adjust or cancel the plan before the crowd forms.

Explanation

Ground risk is time dependent. Event sites can change more in an hour than static maps suggest.
