Oh good. So im not completely stupid then. Thanks for the NPA info.
Agreed the pressurized table is a dogs breakfast.
However, the unpressurized table is fairly straight foward - any ideas why I am getting this question wrong? Is the answer in the book wrong? In the table the reference about crew needing a minimum of 1 hour on transport ops only applies to flight above 13k. So to me it still looks like the answers are 30 minutes, 1 mask, 15 minutes.
Thanks
