Actions for Rapid / Emergency Descent
May be a few minor differences with varying aircraft types, but basically I would think.,
- Oxy Masks on.
- Transfonder 7700
- Throttles closed (A/T out)
- Turn out of airway or away from other traffic.
- Vert Speed to maintain IAS on barber's pole, initially 6000ft/min plus???
- Communicate with Cabin Crew (if possible, but may well not be an option at this time)
- Maintain this config to at least 10'000ft or MSA if higher.
- Assess situation & take appropriate action.
Possibly of course, the very nature of the problem that required a rapid descent in the first place, may well prevent all the above actions being taken in order.
