Ref the question about DG accessibility. I fly MD11F, and my point about the cargo on the main deck is that if it catches fire, the only means of fighting it is two portable extinguishers with a lance, stowed in the Galley area. The lance is about 5 feet long, and as the main deck is about 150 feet long, the only pallets that this can reach are the forward ones. A fire on the rest of the main deck could only be fought by someone going aft with a fire extinguisher, which is impossible unless access is provided.
I know what the ICAO regs say, and IMHO they are inadequate. I am trying to get the company to be more restrictive, but the bean counters won't listen. I'm trying to find out if other carriers have more restrictive rules, then I have some Ammo.
