It carries head down display and shows that (units/kg, display format are "-b to corresponding red negative value b in the corresponding near airports in airport number
Kg "), indicate that the airport can not be returned to safely according to the current fuel load of aircraft, or even throw put it is all it is plug-in can not also return safely,
The airport can be just returned to safely for reminding pilot to need to carry out air refuelling；If airborne display & control system receives airborne ins system
The one or more positive value c and corresponding throwing that system transmission comes put plug-in scheme and corresponding airport number, then it is aobvious to control airborne lower view
Show that device only shows yellow minimum positive value c (units/kg, display format are "+c kg ") in the corresponding near airports in airport number and corresponds to
Throwing put plug-in scheme, indicate to need to throw put it is plug-in could return to the airport safely, and provide specific scheme of putting of throwing for flying
Member's reference clicks yellow minimum that the near airports shows on the occasion of c when needing to check that scheme is put in other throwings of the airport, can be with
It pops up the corresponding all positive value c in the airport and plug-in scheme is put in corresponding throwing.
The landing critical oil content alarm method and system of the application by being calculated and be shown neighbouring each airport in real time
Land critical oil magnitude simultaneously distinguishes expression landing oil mass alarm urgency level by positive and negative values and color display, can make up traditional residual
Oil mass alarm can only be alerted for preset alarm oil mass, and function is relatively single, be unable to satisfy the real-time position of aircraft and become
The defect of change demand and destination change request, compared to traditional residual oil mass alarm method, the application can be pilot
There is provided airfield landing nearby also needs amount of fuel to refer to, and especially under aircraft Fuel Remained stressful situation, needs to choose at which
Airfield landing or when deciding whether air refuelling, is capable of providing effective decision-making assistant information, can be greatly reduced winged
Row security risk.The application can meet aircraft and alert urgency level to neighbouring airfield landing critical oil magnitude and landing oil mass
Real-time requirement.
