As a supplement to the ‘How Do We Fly’ booklet, these points might be worth including in passenger briefing when appropriate:
- stress the 'see and avoid' responsibilities of both pilot and passenger. It's unreasonable to expect passengers to use the clock code, so brief them to point to potential intruders and say 'traffic'. If nearby (detail visible) say 'traffic close'. In a tandem cockpit with the passenger in the rear seat the call can be 'traffic left' or 'traffic right'.
- pilot incapacitation: it would be too alarming to explain to a passenger how to deal with pilot incapacitation. So brief on the use of the PTT, telling them 'if my transmit button fails you'll need to do the comms'. The unspoken message is - if the pilot keels over you can call for assistance on the RT.
