How to Become a Test Pilot
I'm not a TP, not for a few years, but I guess I could offer some advice. I've been asking this question for years to QTPs and FTEs.
1) Join the military and get them to send you to TPS, which costs over 1/2 a million dollars.
2) Get yourself the appropriate tech. background. Aerospace Engineering is good idea. Specialize in flight testing or something related and FLY FLY FLY. Join a major manufacturer as an FTE and work your way up. Make lots of contacts.
I'm working on the same thing. I did a master in Aerospace Eng. and specialized in flight testing and handling qualities...spent numerous hours in motion sims, testing, learning and flying. Currently got my commercial, IFR and looking for work as a pilot to build hours...and then maybe one day.....
Hope this helps
