its the overall layout in terms of logicality, intuitiveness and absence of clutter that is the more important factor.
This is exactly what is required and it has to be designed for the NS Helicopter environment not a FW system modified, to save money, to try and apply to NS ops. It also has to have functions that are Murphy proof so a that it is impossible for a mode to cause the a/c to enter a flight regime in which helicopters weren't designed to operate safely.
