PERFORMANCE COMPARISONS

Note that Mountain Goat STOL™ performance figures are with 26-inch diameter TUNDRA TIRES, while performance figures for the other cited aircraft are with STANDARD AIRCRAFT TIRES. Even with the drag disadvantage prejudicing data against the MOUNTAIN GOAT STOL™ performance figures, MOUNTAIN GOAT STOL™ performance is decisive.

Configuring the other aircraft with 26-inch diameter tundra tires degrades their related performance figures significantly. This is extremely apparent when, at both cruise or climb configurations, at significantly reduced power settings, the MOUNTAIN GOAT STOL™ aircraft readily passes any of the bush fitted, competing aircraft, flying at full power settings.

Note also that mission relevant Mountain Goat STOL™ aircraft figures are given at gross weight ("@gw"), whereas particular cases of data for cited class aircraft comparisons are given at undeclared flying weights.
