Weather Briefings and Sources

← Aviation Weather Products and Interpretationdraft — pending CFI review

Why this matters in flight: Getting a complete briefing from an official source is a required part of preflight planning. Choosing the right briefing type and a trustworthy source ensures you have the current, aviation-specific information the flight actually needs.

There are three briefing types matched to the situation. A standard briefing gives the full picture for a flight not departing immediately — adverse conditions, a synopsis, current and forecast weather, winds aloft, and NOTAMs. An abbreviated briefing updates or fills gaps in information you already have. An outlook briefing is for a departure six or more hours away and provides forecast information only. Where you get the briefing matters as much as which one you request. Official preflight weather comes through Flight Service at 1-800-WX-BRIEF and through approved online and electronic flight bag (EFB) applications built on authoritative government data. These official sources include aviation-specific products — AIRMETs, SIGMETs, TAFs, and NOTAMs — that a consumer weather app may leave out, which is why the official or approved source is the standard for flight planning.

Key terms

Summary

Request a standard, abbreviated, or outlook briefing to match the situation, and get it from an official source such as 1-800-WX-BRIEF or an approved EFB rather than a consumer app.
