Anything which opens up the helicopter market more. So:
1. Whatever Shawn Coyle and Nick Lappos want (wire avoidance, CFIT avoidance, low speed indication etc).
2. Investigate cost effective rotor solutions for high natural stiffness blades, to minimise reduced g incidents in general purpose machines.
3. Fund further development of advancing blade technology into more general purpose high speed helicopters.
4. Develope general purpose control enhancements to allow safe operation in otherwise marginal environments. (eg cyclic and collective response for operation below V-H curve, in VRS, or when at torque limit). Let machine automatically react the way a well trained pilot would (like ABS does for cars etc).
5. Fund research and development into anything which reduces cost and improves performance of general aviation helicopters. The technology will become modular and scalable...
