How long in advance must a PIC receive their flight release prior to operate a flight requiring an IFR flight plan?

• A. No earlier than 2 hours before actual takeoff time
• B. No earlier than 24 hours before takeoff
• C. Immediately before takeoff
• D. 4 hours before takeoff

Answer: (A)

The essential point is that a flight release is the formal authorization to depart under an IFR flight plan, and in CAP operations this release must be in place within a specific time window to keep information current. Issuing the release no earlier than two hours before takeoff ensures that weather, NOTAMs, routing, airspace status, and crew readiness have been reviewed and are still valid at departure. Releasing too far in advance risks the information becoming outdated, while releasing too late could delay departure or leave insufficient time for final checks. Options that push the release to 24 hours, 4 hours, or immediately before takeoff don’t align with the standard practice, so the most reliable window is within two hours of planned takeoff.
