FLIGHT DIRECTOR VERTICAL MODES (Cont)
VERTICAL SPEED MODE (VS)
When the VS mode is selected, the Flight Guidance Computer (FGC) commands the aircraft to climb or descend with a
vertical speed measured in feet per minute. Initially the rate will be vertical speed sensed at the time of VS mode engage-
ment.
Turning the UP/DOWN wheel on the FGP changes the VS reference value. Each click of the wheel is equal to ± 100 ft/min.
APPROACH MODE (APPR)
In the approach mode, the FGC generates commands to track vertical guidance for ILS precision glideslope approaches or
for FMS non-precision glide path (GP) approaches. Approach mode is selected by pushing the APPR button on the FGP.
GLIDESLOPE MODE
Glideslope is automatically selected when in approach mode, inbound, with a valid localizer as the lateral navigation
source. Glideslope mode is cleared by deselection of approach mode. When armed, glideslope mode is also cleared by turn-
ing outbound, or by loss of a valid localizer as the lateral navigation source. When captured, glideslope mode is cleared by
changing the source of the lateral navigation source to anything other than a valid localizer.
Glideslope mode generates commands to capture and track glideslope. Captures can be performed from below or above the
beam. The capture point is a function of the closure rate, with the capture point moving away from the beam for high closure
rates. Capture will not occur if the localizer is not captured, or if the FGC is not receiving valid glideslope data.
Upon glideslope capture, other vertical modes are automatically cleared.
When the APPR capture occurs, the flight directors automatically change to independent mode. When the glideslope cap-
tures are not concurrent and only one side has captured, vertical mode selection, PFD annunciation, etc. operate indepen-
dently on the noncaptured side.
The GS mode is deselected when one of the following occur:
- Another mode is selected.
- Changing the active NAV source.
- VOR/LOC frequency is changed.
- By pressing APPR button again.
- Changing the XFR side when APPR is armed.
- The FDs are turned off while the AP disengages.
Glideslope arm is annunciated by the white GS message in the vertical (arm) field on the PFD.
