I'm 6' 4", and flying is one of the few activities I wish I was shorter for. Assuming you're proportionate (which is a fair assumption based on your occupation), you will feel comfortable in just about any cockpit. If you make it up the ranks and become a flight instructor, your smaller stature will be a benefit as you'll be able to instruct in aircraft that other folks (like myself) simply cannot fold themselves into).
P.S. They're a reason they're called fighter jockeys, and it's not just because because flying a fighter is like riding a thoroughbred.
