Perhaps at DL it would be premature. When the NWA MEC originally started negotiations for the A330 pilot rest facility, prior to the first delivery, the company response was ... Put the pilots in the FA bunk room under the floor at Doors 3L/3R. If former NW management is in charge of this transition, then you need to start the fight earlier rather than later.
How do they plan on adding oxygen to the lower bunk if they stack them in the existing rest area? The current facility has a standard drop down mask coming out of the ceiling panel that would not be accessible by someone in the lower bunk.
The plan is to use the existing bunk room by taking out the jumseat and the rest seat and installing two fixed bunks, one on top of the other. This is the way the rest area is for the A340 etc. Not comfortable but legal.
They are also removing the 3rd jumpseat? Then the PED panel has to be removed. What about the luggage stowage area in the rest facility?
Removing the existing rest seat would also violate the existing JPWA if the aircraft is subsequently operated more than 8 but less than 12 hours:
2. A pilot relief seat will be provided on all aircraft that are scheduled to be operated for
more than eight hours but not more than 12 hours, block-to-block.
d. on the A-330 aircraft:
1) the relief seat will be contained in a separate compartment located just aft of the
cockpit door which contains:
a) one fold-down bunk bed,
b) a fold-down relief seat, and
c) a jumpseat,
2) and is provided with a lockable door to the compartment.
