NotesThe Autopilot Dual Controller is a single panel unit horizontally mounted on the flight deck centre console. It carries the switches and controls necessary for setting up modes and facilities for either autopilot No.1 or No.2 The main switches on the Autopilot Dual Controller are the white 'Engage' switches at the top and the 'Mode Selector' switch at the left side of the panel. To get the aircraft set up for an automatic landing one of the two autopilots is engaged in HEADING mode and aiming to intercept the ILS localizer signal. At circuit height (1500 feet) and decelerated to below 180 kt the autopilot can be set to LOC/VOR to intercept the localizer course which has been set on the CDI. One autothrottle is selected ON with the needed speed dialled in. The autoland sequence starts after this first setup by engaging the other autopilot (no.1 should be activated first, then no.2) and selecting G/S AUTO on the mode selector. The autopilot will intercept the localizer signal at the set altitude and continue to track inbound to the runway. Once it intercepts the glide slope signal, the aircraft will then begin to descend on the approach path. At this point the first indicator above the artificial horizon (GS ENG) will come on, indicating that both autopilots are receiving glide slope signals. The Dual Controller was donated by Saywell International Aviation Centre and replaces a unit which was customer owned and had to be returned
