What is the void time for Weather Brief?

Void time is the window during which a weather briefing remains current for planning a flight. For a Weather Brief, the standard void time is 30 minutes after the estimated time of departure. This means you should obtain a refreshed briefing if you haven’t departed by that time, since weather can change quickly and the information may become stale. A 30-minute window balances having timely data with practical preflight planning; shorter times like 15 minutes would be too restrictive, and longer times like 45 or 60 minutes risk relying on outdated conditions.
