What a neat way to get new ideas for your new job! I fully support this way to poll the industry. Now for my 25¢ worth (for now).
1) Low airspeed sensing systems - we can get a lot more performance out of our machines, particularly Category A, if we had better airspeed information.
2) Dual channel FADEC on all engines
3) tail rotor cameras
4) type ratings for US helicopters - piston, turbine, multi-engine.
Keep up the above average work!
