原来C17货仓只能载40吨最大重量呀
The Boeing C-17 (maiden flight on 15 Sept 1991) and Ilyushin Il-76 (is an older design, with 1st flight of the prototype on 25 March 1971) are the largest cargo jets in the world, with austere and short field capabilities. These jets have both seen their fair share of operating in rugged and remote areas. While there are larger cargo aircraft like the Lockheed C-5 Galaxy and Antonov An-225 Myria), but neither plane has operated in as rugged and remote locations as the Boeing and Ilyushin jet aircraft.

Let's take a closer look between the characteristics of the C-17 (click to see USAF fact sheet) and the IL-76 (with the IL-76 data in brackets), side by side below, as a starting point for further discussion:

General Characteristics
Wingspan.: 51.75 m .....................(50.50 m)
Length......: 53.00 m ......................(45.69 m)
Height.......: 16.79 m ......................(14.76 m)
Thrust.......: 40,440 pounds each...(26,500 pounds each*)
Crew.........: Three............................(Five?)

* The thrust figures on the Indian IL-76 may not tally, as I'm not sure about Indian modernization programmes (guys, please feel free to correct, if I've got my facts wrong on the IL-76)

I've not bothered to put in the max payload as the USAF uses a term called "Allowable Cabin Load" (ACL) for its transport aircraft. It is a planning figure used to determine the optimum average load its transport aircraft would carry during deployments. Although the C-17 can carry a maximum payload of 77 to tonnes, that figure is seldom reached because the ACL figure of 40 tonnes is lower than the maximum payload. In fact, the average C-17 load during both OEF and OIF averaged just around 18 tonnes (metric) on deployments.

As a newer design, I would expect that reliability and maintainability are benefits of the C-17 - which will in turn affect sortie generation. According to the USAF, the C-17 has an aircraft mission completion success probability rate of 92%, only 20 aircraft maintenance man-hours per flying hour, and full and partial mission availability rates of 74.7% and 82.5%, respectively. The Boeing warranty assures these figures will be met.原来C17货仓只能载40吨最大重量呀
