How much fuel does the Super Caravan burn compared to the OEM PT6 Caravan?
The TPE331-10 Otter burns approximately 5 gals/hr less than the PT6-34 Otter for the same speed/horsepower. Initial flight test data shows that the TPE331-12JR SuperVan is burning around 3 gal/hr less than the OEM Caravan under similar conditions. The fuel specifics calculations on the PT6A-114A engine show that the fuel burn would be higher than what the Caravan Flight Manual shows. We saw higher fuel burns with the PT6, but ours was a high time engine. TTC, Inc. will continue to update the performance section on the website as more flight testing is completed.(See FF chart & (See fuel burn calculations page).
