I would like to see a complete redesign of the human - helicopter interface.
First of all I would concur with contributors over the pilot seating position, this must be the weakest feature in all aircraft (17) I have flown.
No overhead panels
Heaters and Air Con
Seats
Intercom
VISIBILITY - I need to be able to see !
I would like to see two VDUs. One central in Display by Exception mode which only shows if something is not right. In front of me I would like a screen which I can customise to show important stuff where and when I want.
Minimum switches, no circuit breakers.
No vibration
