SECTION 4 - NORMAL PROCEDURES (CONT'D)
NOTE
Manual HSI course centering in OBS
using the control knob can be difficult,
especially at long distances. Centering the
dbar can best be accomplished by pressing
[ D ] and then manually setting the HSI
pointer to the course value prescribed in
the KLN 90B displayed message.
6. GPS approach (GPS APR ARM/ACTV) switch/annunciator - Used
to a) manually select or deselect approach ARM ( or deselect
approach ACTV) and b) annunciate the stage of approach operation
either armed (ARM) or activated (ACTV). Sequential button pushes
if in ACTV would first result in approach ARM and then approach
arm canceled. Subsequent button pushes will cycle between the
armed state (if an approach is in the flight plan) and approach arm
canceled. Approach ACTV cannot be selected manually. GPS APR
and ARM are white. ACTV is green.
7. RMI NAV presentation switch - May be used to select data for
presentation on the RMI; either NAV 2 data from the number two
navigation receiver, or GPS data from the KLN 90B GPS.
C. PILOT’S DISPLAY
Left/right steering information is presented on the pilot’s HSI as a
function of the NAV/GPS switch position.
D. AUTOPILOT COUPLED OPERATION
The KLN 90B may be coupled to the autopilot by first selecting GPS on
the NAV/GPS switch. Manual selection of the desired track on the pilot’s
HSI course pointer is required to provide course datum to the autopilot.
(Frequent manual course pointer changes may be necessary, such as in
the case of flying a DME arc.) The autopilot approach mode (APR)
should be used when conducting a coupled GPS approach.
NOTE
Select HDG mode for DME arc intercepts.
NAV or APR coupled DME arc intercepts
can result in excessive overshoots
(aggravated by high ground speeds and/or
intercepts from inside the arc).
