The 'Big Lifter'
It is nearly 40 years since I flew the B214 but as I recall it, at 16,000 lbs you had to have some of the weight on the hook.
The other reference to its impressive time to height is only applicable if you are operating outside the Flight Manual vertical speed limit (2000 fpm?). From personal experience I know that even at 16,000 lbs and ISA +20° at 10,000 feet you could still be doing 4000 feet per minute rate of climb unless you reduced power. As I recall it, the concern was that inertia would keep the aircraft going up following an engine malfunction and that it may not be possible to get into autorotation.
