Salary
Just crunched the figure.
Flying 100hrs in a month your get $12,500.
That is no night stops.
Add $2400 for housing and transport and you come near the figures they quote.
BUT as I said, you don't do 100 hour months, and you need to spend your housing on a compound.
Also the money for trainers. NAS does not employ trainers directly. We have many JAA TRI/TRE's here and also FAA Full Check airmen, and they are not trainers. There is a lot of politics about trainers... I'll leave that there but sure you can read betwen the lines!
