COMMERCIAL AIRCRAFT 86 South Cobb Drive, Marietta, Georgia 30063-0264, USA; tel: +11770) 494 4411; fax: +1 (770) 494 2529; telex: 542642. L-100 HERCULES The L-100-30 is the civil version of the C-l 30 Hercules military transport. It has US certifica tion to carry- 97 passengers when appropriately modified or manufactured. The passenger version has structural re inforcement, windows, and additional doors, plus improved environmental conditioning and emergency lighting. Modification from the basic freighter adds 12,710kg to the MTOVV. Southern Air Transport has developed a pas senger/cargo "comhi" modification for the L-100, which enables the aircraft to carry up to 18 passengers and five main-deck pallets. A commercial version of the new-generation military CM 30J Hercules, intended initially to be a pure freighter and flown in April 1996, has been proposed. The aircraft will have a glass cockpit (with provision for head-up displays), Allison AE2100-D3 turboprops and Dowry R391 six-bladed propellers. There is an option al 3.5m-wide door in the forward fuselage, which allows an additional, sixth, pallet to be carried. There is room for a seventh pallet, courtesy of a modified ramp. Compared with earlier 1.100s, it should have a 61% payload-range improvement, 15% increase in block speed, 21% decrease in fuel consumption, 38% decrease in crew cost and 69% decrease in maintenance costs. Delivered 115 L-1011 TRISTAR The L-1011 TriStar had its first flight in November 1970. A total of 249 was delivered between 1972 and 1983, when production ceased (the prototype was never sold), of which some 200 remain in existence. Production included 200 "long-body"TriStars (-1, -100 and -200) and 50 short-fuselage, extended-range, - 500s. All were powered by the R-R RB211. Lockheed developed several after-market upgrades for the long-body TriStar, which included various weight increases and addition al fuel capacity, to provide better payload/range performance. An upgrade to -100 specification was available, as well as modification packages which created three new variants (never deliv ered new) - the -50, -150 and -250. The latter was the most radical conversion developed, and combines the uprated R-R RB211-524B4I of the -500, with additional fuel capacity and higher MTOW (through struc tural strengthening) to give a 9,410km range. Marshall Aerospace offers a cargo-conver sion programme for the TriStar, and has deliv ered 12 -200 freighters, the first to American International Airways in August 1995. In May 1998, Lockheed Martin Aircraft & Logistics Centers and AAR Airframe & Accessories Croup formed an alliance to pro vide fleet support for the TriStar.
