First, don't bring up the salary until they offer you the job. You don't want to be too expensive to hire and you don't want to undercut what they were prepared to offer you.
Sounds like the TAPs class must be very standardized!
Second, let them know that you might need time once your training is done to move your family. As an employer I'd expect your spouse to be able to get most of the move organized and complete
You must be military!
Moving is spouse work! You need to get to work!
Ask about the ratio of flying to investigations. Ask what kind of investigations you'd be doing. Ask about the type of flying (ie. destinations, weekends, business or pleasure). If the passenger is going to be on the ground for a set, lenthy period of time ask if you can fly the aircraft home or commercial home rather than remaining at the destination for several days.
I think this is very important. If you are looking at the salary range for a PILOT, but then you get saddled with these additional duties that constitute a certain portion of your daily/weekly duties for instance - well you should be properly compensated for them too. You don't want to be getting paid for as a standard pilot and working three times as hard!
