  • Automated control of aircraft utility subsystems on the MD-11

    Publication Year: 1992, Page(s):592 - 596
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (320 KB)

    One of the unique features of the MD-11 is the use of aircraft system controllers (ASCs) to operate the aircraft utility subsystems. Essentially, these controllers perform most of the same functions that were previously performed by the second officer on the DC-10 aircraft. This allows the MD-11 to be operated by a two-member crew versus the three-member crew required for the DC-10. The authors di... View full abstract»
