1. adjustable seats so we can use an eye reference point just like the plank drivers. That way we can see the instruments properly and save our backs.
2.more POWER! Cut the stress on those hot and calm summer days, give us a full N-1 flyaway capability.
3. wide CoG envelope, so we stop having to drop payload because it takes us out of CoG even though we could take the weight.
4. easy numbers for limitations.
5. make 'em comfortable, especially for pax as they have to pay for it in the end..
6. make them safe from a ground staff point of view. Too many fatalities caused by low S76 rotors.
