JohnAircraft air fuel discharge means that the fuel is not consumed before the aircraft lands, and the fuselage weight exceeds the landing weight specified in the regulations and standards. In this case, the aircraft can only discharge fuel in the air in order to land safely. When the aircraft discharges fuel in the air, it will dilute the released fuel through atomization.
Expansion materials:
When taking off, the aircraft needs to carry sufficient fuel and a certain amount of standby fuel required for the whole flight. When arriving at the destination as planned, the fuel consumption carried by the aircraft is basically the same as expected before takeoff. At this time, the fuselage weight of the aircraft meets the takeoff and landing standards. However, once the aircraft needs to land soon after takeoff, the fuel carried by the aircraft is not consumed. At this time, the fuselage weight exceeds the landing weight specified in the regulations and standards. In this case, the aircraft can only discharge oil in the air in order to land safely.
Air refueling is of great significance in both military and non military fields. In most cases, if the aircraft requires immediate landing due to failure after takeoff, the landing weight at this time will exceed the maximum landing weight of the aircraft. In order to reduce the weight of the aircraft and achieve the weight of safe landing, air refueling is necessary.
