Which option lists the FSS phone number in a shuffled order?

1-800-Wx-Info

1-800-Wx-Route

1-800-Wx-Help

1-800-Wx-Brief

FSS numbers use the format 1-800-WX-XXX, where the last part designates the service. BRIEF signals a full weather briefing, which is what you typically need before a flight. Dialing 1-800-Wx-Brief gives you a comprehensive briefing that covers weather, NOTAMs, airspace, and other flight planning details. The other options represent separate, less complete services (information, routing, or help) and aren’t the correct choice when the prompt specifies a weather briefing.
