System 40X
  • Single axis, roll stabilization autopilot
  • 3" ATI programmer/computer
  • System includes seperate programmer/annunciator (shown above), turn coordinator, servo, and pressure transducer
  • Includes heading mode, NAV/APR/REV intercept and tracking, course deviation / NAV flag warnings, roll stabilizer, and control wheel steering (CWS)
  • Stabilizer mode is controlled by roll modifier button mounted on control wheel
  • Capable of turn commands up to 90% of standard rate turn
  • Rate-based system, deriving roll axis control inputs from separate electric turn coordinator
  • Gain enhancement feature for use when tracking GPS & LORAN input signals
  • Includes GPSS steering feature for use with GPS receivers that have roll steering outputs
  • Heading Pre-select is optional* by adding S-Tec course selector Dir. Gyro or HSI with autopilot outputs
  • Building block concept allows upgrading to two-axis System 50 X
  • Manual electric trim option* available
  • Please Note: This system requires a compatiable heading system for heading preselect and NAV intercept capability. If a compatible heading system is not installed, the autopilot reverts to tracker only (no intercept capability) when using any NAV modes

  • NOTE:
    GPSS feature only compatible with GPS receivers that have ARINC 429 outputs and Low Speed Label 121 (bank angle command) and Low Speed Label 312 (ground speed)
