Weather
Wind, rain, visibility, temperature, precipitation, and rapidly changing conditions can delay, modify, or prevent a flight even when ground photography continues.
Airspace
Some locations require authorization or have flight limitations. Approval may depend on location, altitude, time, and the nature of nearby airports or restricted areas.
Site conditions
Power lines, trees, people, traffic, neighboring properties, animals, emergency activity, and secure launch and landing space all affect the operating plan.
Scheduling
When aerial media cannot be captured safely, the next step may be a reschedule, alternative ground coverage, or removal of the aerial deliverable as agreed during booking.
