When I went through my bridging in 2002, you needed 2000hrs in section 5 column 7 of your log book.
That is, 'total flying, columns 1-6', which means not including sim time.
A minimum of 2000 hours* flying experience on military aircraft,
(Is a simulator a military aircraft in the LASORS definition given above??)
The 1500 hrs could however include sim time.
A call to the FCL dept will surely clear it up,
however it also seems a bit strange that there are 'individual cases' out there.
Is the tgda site still working?
