AUTOMATIC FLIGHT CONTROL SYSTEM
The bank angle can also be toggled between high and low bank limits by means of the
BANK switch on the guidance panel.
When heading or VOR mode are active with the low bank limit, an “eyebrow” is
displayed between ± 17° on top of the attitude sphere on the PFD.
Lateral Navigation Modes
Lateral navigation mode is activated by selecting the NAV button on the guidance
panel. The following navigation sources may be activated:
•
Very high frequency Omnidirectional Range (VOR)
•
Localizer (LOC)
•
FMS Lateral Navigation (LNAV)
If in (ROL) mode when (NAV) is selected, heading select mode is automatically
activated. A capture of any armed lateral navigation mode will cancel the heading
mode.
Lateral navigation guidance and automatic transitions are computed based on the
following data, received from the selected PFD:
•
Lateral path deviation (VOR and LOC)
•
Course or heading error
•
NAV source identification (VOR, LOC, FMS)
•
