Ditzy,
Sorry but that is incorret. Australian CAR's and CAO's are very strict when it comes to pax and crew.
Quoting CAO 20.16.3
3.1
"Each crew member and each passenger shall occupy a seat of an approved type:-
a) during t/o and ldg
b) during an instrument approach
c) when the aircraft is below 1000ft AGL
d) in turbulent conditions
The only exceptions to this are
a) stretcher cases, carried in accordance of CASA requirements
b) package dispatchers
c) parachutists
It should also be noted, that if the aircraft is therefore required to conduct any form of instrument approach due weather or ATC requirements, then the crew must be seated & therefore not be preforming CPR for the entire duration of the approach, which could begin a fair distance (+10 miles) from the airport.
The PIC and cabincrew have no discresion when it comes to the above requirements.
Cheers
stormy
