When must a jumpsuit rider receive a verbal briefing from the captain?

A jumpsuit rider must receive a verbal briefing from the captain before takeoff to ensure that they are fully informed about safety procedures, emergency protocols, and any specific instructions relevant to their role during the flight. This timing is crucial, as it allows for the communication of important information when everyone is still on the ground and can address any questions or concerns before the flight commences. Providing this briefing before takeoff ensures that the jumpsuit rider is prepared for their responsibilities as soon as the aircraft departs, enhancing overall safety and readiness.

The other timing options—before landing, during taxi, or after takeoff—would not be appropriate for delivering comprehensive safety briefings. In these scenarios, the focus is generally on landing preparations, ground operations, or in-flight duties, respectively, rather than a thorough briefing which needs to occur while the aircraft is stationary and prior to initiating flight operations.
