2 pilot-crews in IFR certified, all weather-capable (including "known icing") twin-engined helicopters capable of Cat A departures at max gross any place in the AO, any time of the year, with 3 hours of fuel. While we're at it, how about: in-flight refueling; hot and cold running flight attendants; and a fully stocked wet bar on board...
I'd settle for: helipads at hospitals, not to mention at trauma centers; NVG capability; and pilot scheduling that considers human physiology. That last factor is the single most important change required in the industry. No amount of added bells, whistles and engines make up for a stupid pilot- in fact they increase the possibility of error by increasing the work load and decreasing the margin for safely acceptable error.
The industry- and pilots- schedule night duty too casually. Most people lose intellectual capacity with sleep disruption, sleep loss, and the circadian upset that comes with abrupt day to night transition- yet that's the rule for pilots in the industry.
