MIMPI4D Complex logic exists to deal with multiple failures, which may prompt the system to revert to simpler back-up modes. A newer flight control system, called intelligent flight control system (IFCS), is an extension of modern digital fly-by-wire flight control systems. Modern airliners also commonly feature computerized Full-Authority Digital Engine Control systems (FADECs) that control their engines, air inlets, fuel storage and distribution system, in a similar fashion to the way that FBW controls the flight control surfaces. Fly-by-wire control systems allow aircraft computers to perform tasks without pilot input.|{3|4|5|6|7|8|9|10|Three|Four|Five|Six|Seven|Eight|Nine|Ten} Things You Have In Common With Slot Valve
