Shawn, good idea

I think that the new 'record' criteria should be in the form of an index so that an easy comparison can be made between types.

I reckon this could be usefully be expressed as a percentage of the max GW of the helo on the ramp in sea level ISA, compared to the max payload that the helicopter can actually carry at an IGE hover at 3000' at ISA.

For example: helo Max GW = 2500lbs at sea level ISA, helo can hover (conditions as mentioned) with payload of 400lbs, therefore 'index' percentage is 16%.

The value would be in being able to compare how quickly different helos payload performance deteriorates with altitude and also allows a meaningful power-to-weight ratio comparison to be made between types (without wading through the tables).
