Question 1 of 24
A remote pilot wants a preflight weather briefing from Flight Service before a drone flight. Which of these is the correct way to get one?
Why: AC 107-2A Appendix B.3 directs remote PICs to obtain weather information from Flight Service through 1800wxbrief.com, where they can create a free account to use the briefing service, and states that Flight Service's telephone-based briefing service is intended for manned aircraft pilots only.
- Assumes the Flight Service phone briefing line is open to remote pilots; AC 107-2A explicitly limits it to manned aircraft pilots.
- Invents a weather-briefing role for ATC — air traffic control facilities do not provide preflight weather briefings; Flight Service does.
