OK, if I assume a slick Huey weighs about 5k pounds and tops out at max gross weight at 10k, and a slick Blackhawk is about 12k empty and 22k max gross: The Huey 2 is hovering IGE at 12k msl at 11* C (ISA +20) typical Huey hover altitudes are 3ft. A slick Blackhawk (UH-60L) is hovering at 10 feet with a torque margin of 6% with the same load with the same fuel duration. In other words, the Blackhawk out performs the Huey 2 in high hot performance with the same conditions.
ETA: I boogered up the math, they end up having about the same performance at those high altitudes as far as hover performance is concerned.
The difference is that with expanded capability, we end up hauling around more new age gear, so our aircraft are just heavier than past aircraft both in real numbers and percentage wise.
