When should the approach briefing be completed?

The approach briefing should be completed before the descent from cruise. This timing is crucial because it allows the flight crew to thoroughly review the approach procedures, weather conditions, potential hazards, and any special considerations well in advance of actually starting the approach. Conducting the briefing at this stage ensures that all crew members are aligned on the plan and have sufficient time to address any uncertainties or questions before entering the approach phase of flight. It also helps to enhance situational awareness and allows for a smoother and more coordinated transition from cruise to approach.

Completing the briefing while taxiing, after reaching the final approach fix, or upon landing does not provide the same level of preparedness and could lead to rushed decisions or missed information. Prioritizing the timing of the approach briefing ensures that the crew is adequately prepared, reducing the likelihood of errors during the critical phases of flight that follow.
