What is the recommended interval for briefing crew members before a flight?

The recommended interval for briefing crew members before a flight is at least one hour before departure. This timing allows adequate opportunity for all crew members to assimilate important information regarding the flight mission, safety protocols, and any relevant operational details. An effective briefing contributes to enhanced situational awareness and establishes clear communication among crew members, which is essential for coordination and successful flight operations.

Briefing too close to takeoff or only making it contingent upon changes in the flight plan can lead to inadequate preparation and misunderstandings among the crew. By conducting the briefing at least an hour before departure, all members have sufficient time to discuss key points, ask questions, and clarify responsibilities, ultimately promoting a safe and efficient flight environment.
