引用wikipedia air force 1和fuel dump首先,air force 1是747
since 1990, the presidential fleet has been two Boeing VC-25As, which are specifically configured, highly customized Boeing 747-200B series aircraft. The Air Force plans to procure the Boeing 747-8 for the next version of Air Force One.
然后,747是有fuel dump的option的, 而且至今为止我还没见过哪架747没选配这个功能
hree- and four-engine jets like the
Lockheed L-1011,
McDonnell Douglas DC-10/
MD-11,
Boeing 747and
Airbus A340usually have difficulty meeting the requirements of FAR 25.119 near maximum structural takeoff weight, thus most of those have jettison systems.
