For example, range to a helicopter 3000 m away and 2000 m up is treated as 4000m (3000 + 2000/2).
(The math answer is 3605.551 m).
And if that same helicopter closes to almost overhead... 300 m away and the same 2000 m up is treated as 2150 m (300/2 + 2000) = 2150
(the math answer is 2022.375 m)
It's an approximation, but it's within 10-12% accurate, which isn't bad for something you can do in your head.

This would indeed streamline the rules and drop the need for a conversion table. It would also remove several altitude bands, effectively leaving NOE, Low, Medium and High, I suppose.
Thank you for the idea. I was clearly approaching this in a far too complex manner.
