    Conditions (VMC), prior to using it under Instrument Flight Rules (IFR). 1.3 General Control Theory The System Fifty Five X is a rate based autopilot. When in control of the roll axis, the autopilot senses turn rate, as well as closure rate to the selected course, along with the non-rate quantities of heading error, course error, and course deviation indication.

    S–TEC 3.1 Normal Operating Procedures 3.1.1 Heading (HDG) Mode Set the Heading Bug to the desired heading on the compass card (HSI or DG), and then press the HDG mode selector switch to engage the heading mode. The HDG annunciation will appear as shown in Fig. 3-1, to acknowledge that this mode is engaged.
  • Page 39 S–TEC If the Course Deviation Indication (CDI) is at full scale (100%) needle deflection from center, then the autopilot will establish the aircraft on a 45° intercept angle relative to the selected course. Even if CDI needle deflection is less than 100%, the autopilot may still establish an intercept angle of 45°, provided that the aircraft's closure rate to the selected course is sufficiently slow.

  • Page 40: Remote Annunciator Display, Nav Mode Engaged, Cap Condition

    S–TEC While tracking in the SOFT condition, the autopilot ignores short term CDI needle deflections (excursions), to thereby inhibit aircraft scalloping during VOR station passage. Should CDI needle deflection exceed 50% for a period of 60 seconds, the autopilot will revert to the CAP SOFT condition as a means to re-establish the aircraft on course.

  • Page 45: Automatic Elevator Trim

    S–TEC Should the pitch servo loading exceed a preset threshold for a period of three ∧ ∨ seconds, the autopilot will annunciate either Trim or Trim as a prompt to trim the aircraft in the indicated direction. This is shown in Fig. 3-14. In addition, an audible alert will sound a periodic tone.
