Right from the QRH:
Before Take-off
1.) PRES CONT switch - AUTO
2.) EMER DEPRESS switch - ON
3.) L and R PACK switches - OFF
4.) 10TH STAGE, ISOL - CLOSED
5,) 10TH STAGE L and R BLEED AIR - CLOSED
6.) RAM AIR switch - OPEN
---END---
At a safe altitude, preferably between 1500 and 3000 feet above field elevation:
After Take-off
1.) RAM AIR switch - CLOSED
2.) 10TH STAGE, L and R BLEED AIR - OPEN
3.) L and R PACK switches - ON
4.) EMER DEPRESS - OFF
Note:
If an engine failure occurs, delay turning on the bleeds until after obstacle clearance is assured.
---END---
Don't forget to confirm those guarded switches with the PF, don't forget the after takeoff check, don't forget to contact departure, etc...
Like I said earlier, sure, it can be done, but for this to be the new "norm" is just ridiculous.
I'm glad this has been rescinded - for now. It is my understanding that the FAA isn't backing down, and certain operators are just telling their pilots not to do it, which would seem to put those pilots in a precarious position.
