loadmasters and DGR
Just a couple of points on the loadmaster issue,
Firstly, IF and it is a big IF, the fire started in the dangerous goods then if my memory serves me correctly then all the DGR should be loaded in an accessible and visible position, this means no DGR on the lower decks and none in sealed ULD’s . Accessible is a moot point, a “who ate all the pies” crew member might not be able to get down the aisle between the cargo and the walls, I believe this is a particular issue is some configurations on the B777F.
With regards to the loadmaster on the flight, a two crew operation would presumably precludes either of them leaving the flight deck to investigate the fire warning and I assume the fire warning checklist for a two crew operation reads thus
1. Get on the ground quick.
2. Why are you not on the ground yet?
A third crew member, be it a loadmaster or third pilot allows one person to go back, investigate and possibly fire fight. I guess though there is a trade off between the increased insurance premiums and the salary of the third crew member.
