Although the operating cost per hour of the C27J appears to be higher than the C295, a closer examination will show that the C27J is more efficient than the C295 as demonstrated by the higher total productivity and lower cost per ton ratios.

The C27J includes an in-flight fully operable APU which:

Allows operations on fields with no ground support equipment

Re-starts engine without limitations on ground and in flight

Significantly improves mission reliability and aircraft survivability
