Aircraft Model (Name & Manufacturer)
Boeing 747-400M Combi by Boeing
Aircraft Category
E
Purpose or Role in Game
A combined cargo and passenger aircraft, hence the combi moniker. Would offer a unique strategy as the aircraft can fulfill both passenger and cargo demand simultaneously. This could be an interesting way to enhance player strategy, sending a very large aircraft to a destination with lower demand, making up for it through the cargo revenue.
Why should this aircraft be added?
While the aircraft was quite niche, being most prominently used by KLM and Lufthansa, it’s a very unique aircraft as it’s the largest combi ever produced. Given that the B744 already exists in-game, I would imagine that the development cost of adding this variant would be quite low. The biggest change likely being the implementation of the cargo door animation, however, this should be similar to existing cargo aircraft such as the B77LF. Other changes would then be related to performance and handling times.
Airlines that use it
All B744M aircraft have sadly been retired or scrapped. Historic operators include:
KLM Royal Dutch Airlines
Lufthansa
Air China
EVA Air
Air France
Asiana Airlines
Special characteristics or variants
Dimensions are identical to the B744 with the exception of the rear main-deck cargo door. The combi aircraft exists with all engine options including the GE-CF6 (KLM, Lufthansa, EVA Air) and Pratt & Whitney PW4000 (Air China). The Rolls Royce variant was an available option, but to my knowledge, no combi aircraft were delivered using the RR engines.
