There's enough O2. and you and pax should be on O2 before the E.D is commenced. I'd always thought good teamwork in an emergency required good communications
Quite agree.
do you really want an RA telling you to adjust your Emergency descent?
Fine by me as long as im not frosting up
Is this the best team work? What's the rush
Good team work always start with proper SOP and crews being properly trained and implementing them if and when the day comes.
on the subject, should we ask ATC if they want us to squawk 7700?
If you are declaring an 'emergency descent' rather than a rapid descent due a slower loss of cabin pressure the squawking 7700 answer lies in the first word of your declaration..
Declaring is not requesting...you are telling them you are about to lose quite a few levels in the next 6 or so minutes rather than requesting their permission.
