Helo Performance

Hi zic; re your post #124.

Am just briefly revisiting this thread and then off again for a while.

We have to consider a common benchmark when making performance comparisons so let's make that IGE hover at maximum operating gross weight (MOGW) in ISA+20C conditions. Altitude capability for the Huey II in that respect is 12,000 feet. You guys at Oakey should have the performance manuals for Blackhawk, Tiger, MRH90 and I am sure thread viewers would be interested to see the comparable performance for those types.

The first image is a bit non-specific in that regard and should relate to IGE (not OGE hover) according to other written performance data provided by Bell Helicopter. No crew composition nor weight mentioned for individual passengers so the number of figures illustrated might be less for a 4 person crew; but the table gives reasonable relative comparisons between Huey II and UH-1H. The second image gives some very interesting maintenance comparisons.

It is of course all a bit academic as far as the ADF is concerned because the Australian Government/Defence/DMO/Army Aviation seem determined to shed the true utility helo capability.
