talking of First Choice G-OOAN and AL have the 3 door config all being large doors. They are keeping OOAN as they refurbish, however the new ones they are getting from Vietnam, have 2 front, 1 overwing small door and 1 large back door, so this means they are going to have to produce 2 types of safety card, which is a bit of a hassle.
We always had amendments in our manuals back in the AMM days topjet. AMM had a very mixed fleet of 757’s then. Some with toilets 2 forward and two mid, some with 1 forward and 3 mid, and thats just the loo’s! The safety equipment was in a different place on every aircraft, and this all had to be documented in the crew SOP manuals. Some had life rafts for ETOP’s, some not.
All I can say is… the training courses were an absolute nightmare! I think a few different safety cards is the least of their worries. Think of the poor crew with all their different sections in their manuals for each aircraft 😮
