|Trident Panel Manual|
|The autopilot is a separate
window from the main panel. It is toggled on/off by the toggle
button marked 'AP'
In the VC, the AP panel is positioned in the middle of the pedestal.
1 : Azimuth & Pitch Switches (AP Master Switch)
Simple FS Master On/Off for autopilot functions.
The flight director can still use the different modes if the autopilot is off.
Auto throttle works independantly of the autopilot master.
2 : Damping
Works as Yaw damper in FS.
3 : F / Dir
Flight director On/Off button.
The Flight director displays required bank & pitch commands on the attitude indicator (main panel).
FD can be switched off while the autopilot is running and FD can also be switched on while the autopilot is off.
: Azimuth Master
This button activates both Heading Hold AND Nav Hold.
On the real aircraft, this button could also be twisted to set the maximum bank angle for the auto pilot. In the model max bank angle is fixed at 20 degrees (which was normal on the Trident).
Heading mode or Nav mode is set using a switch on the Horizontal Situation Indicator (main panel).
The switch points up for Nav mode & points right for Heading mode. The relevant 'bug' is pictured next to the switch.
The Heading and Course (Nav) to hold are set using the knobs on the HSI.
6 : Prime Switch
Selects the use of Approach mode and Autoland.
In the 'Off' position, Heading Hold & Nav Modes can be used.
In the 'Glide' position approach mode is active. It will capture & follow any ILS beams tuned to NAV1.
In the 'Land' position, Glide is active and full auto land is also active.
The model does not require that you press the 'Engage Glide' button (bottom right). Selecting the Prime Switch to 'Glide' or 'Land' will always engage that particular mode as well.
Similar to the real thing, Auto land activates a more accurate approach phase in the model at around 1000ft (radio Alt) and (hopefully) guarantees that the aircraft will land on the runway, even in a strong cross wind.
At the correct moment, Auto land cuts the throttle, performs a flare and uses the rudder to kick off any drift to land as straight as possible on the runway.
