Actually, Flying Frypan, Section 2 of the Document I linked to previously
(here it is again for those who missed it) states clearly:
"This instrument
applies to the aircraft mentioned in Schedule 1 operated by Virgin Blue Airlines, Aviation Reference Number 567591 (
the operator) and engaged in Regular Public Transport operations"
Schedule 1 states:
"Schedule 1 Aircraft
Australian registered Boeing 737-800 series with a type data certificate that provides for a maximum seating capacity of 189"
There is reference made to the 1:36 ratio and CAO 20.16.3 in the explanatory notes, but nowhere does it state that the ratio has been changed across the board - only in this "instrument", which applies only to the B737-800 aircraft configured with 189 pax or less.
This is not a good thing folks
