1. Confirm the type of operation
Before anything else, know whether you are operating recreationally or under Part 107, because qualification, registration and operating requirements differ. Use the FAA's current UAS guidance as the source of truth.
2. Check registration and Remote ID status
Confirm the aircraft is registered when required and that any applicable Remote ID requirements are satisfied. Make this a paperwork/equipment check before you travel to the site, not a surprise at launch.
3. Review airspace and location
Check whether the planned area is controlled or otherwise restricted, whether authorisation is needed, and whether temporary or local restrictions affect the operation. Identify a launch area, recovery area and an alternate landing option.
4. Check weather against your real limits
Look beyond a single wind-speed number. Consider gusts, direction, visibility, precipitation, temperature, battery performance and how conditions may change during the flight.
5. Inspect the aircraft
Check airframe, props, motors, batteries, controller, storage, navigation status and failsafe settings. The manufacturer's manual and any operator maintenance procedure take priority over this guide.
6. Brief the failure plan
Decide what you will do for lost link, unexpected people entering the area, deteriorating weather, low battery, navigation anomalies and an obstructed landing area.
