APPROACH (APPR/ARM AND APPR/

CPLD, GS/CPLD) MODE

The APPR mode provides visual roll and pitch commands on
the FCI V-bar to capture and track precision ILS (LOC and
Glideslope) beams, or non-precision VOR or RNAV radials.
Lateral and vertical deviation can be monitored on the PNI.

Operation of the APPR mode requires the pilot to:

1 .

Set the NAV receiver frequency.

2 .

Set the PNI course pointer to the inbound runway
heading or the front course in case of ILS precision
approach. Do this even on back course approach.

3 .

Set the HDG SEL “bug” on the PNI to the desired
intercept angle and activate “HDG” mode.

4 .

Depress the ”APPR“ button on the mode controller.

The automatic APPR capture function will be imme-

diately armed. “APPR/ARM” will be lighted on the Mode
Annunciator Panel. In APPR/ARM mode, prior to capture,
HDG is retained to allow the pilot to adjust heading to
Approach Control vectoring instructions.

The LOC beam or VOR/RNAV “capture“ point will vary,

depending on angle of intercept and rate of change of devi-
ation indication. Upon capture, a bank command will be
introduced on the FCI, the existing heading mode will be
cancelled and APPR/CPLD will be lighted on the Annunciator
Panel.

The pilot may manually bank the aircraft to satisfy the

command display, which will command a rollout to wings
level when the aircraft is on course. Automatic crosswind
compensation will provide precise tracking.

VOR/LOC deviation is shown on the PNI, and actual crab

angle will be shown by offset of the course arrow from the
lubber line.

Throughout APPR,mode operation LOC and Glideslope

deviation or VOR/RNAV deviation are displayed on the PNI.

If the Autopilot is engaged during operation in the APPR

mode, automatic steering response will follow the com-
mand display on the FCI. The Glideslope mode is armed for
automatic capture if LOC front course capture has occurred.
Automatic Glideslope capture occurs as the aircraft
approaches the glide path from above or below. Upon inter-
ception of the Glideslope, capture occurs and “GS is lighted
on the Annunciator Panel. A smooth capture pitch command
is displayed by the Command V-bar. The pilot (or Autopilot)
controls the aircraft to satisfy the Command V-bar. Slewing
ALT at time of GS centering will inhibit GS capture.

Upon GS capture, the ALT HOLD mode (if active) is can-

celled. However, ALT HOLD may be manually reselected to
maintain altitude upon reaching MDA if visual contact is not
established.

During VOR or RNAV approaches, Glideslope capture

will not occur because the NAV receiver is channelled to a
VOR station, not an ILS, and this locks out the Glideslope
function.

APPR/CPLD mode is cancelled by selection of HDG, NAV.

or Go-Around modes, or pushing FD or APPR to “OFF.”

BACK COURSE (BC) MODE

Whenever a LOC or ILS frequency is selected, the BC mode
may be activated by depressing the BC button on the Mode
Controller, after selecting APPR. When in BC mode and
