I'd make the cabin crew 5c and include instruction to them as to whether the landing is to be normal, precautionary, or planned emergency, and add:
5a Radio call to company advising them of the situation and perhaps asking for instructions or advice
5b Reassuring PA by captain explaining in very simple terms what has happened and what the plan is,
and I would comment that Mike is right to indicate that sometimes it's better for the captain to leave the co-pilot flying, or hand control to him, although at other times it's better for the captain to stay in control or take control, although of course some companies dictate that the captain (or commander) must take or retain control (qv Boeing procedures for emergency descent).
Given the perspective of the original questioner, we should also say that this is all carried out in the context of 'aviate, navigate, communicate'. Therefore, the first priority is always to fly the aircraft at the right speed and in the right configuration, the second is always to fly it in the right direction at the right altitude (this may introduce the complexity of an emergency turn, special engine out procedure, escape route, or the like, which may demand significant care and attention), and communication with ATC, cabin crew, or passengers is last in the list.
I'd still love to know how we're discussing
confidential company information here... Does the DFO know that his ASRs get replicated on PPRuNE?
