NOTES:
1. When flying a localizer intercept, the optimum
intercept angle is 45
_
.
2. The pilot should not intercept the localizer at angles
greater than 90
_
. At angles greater than 90
_
, the
system automatically captures the back course.
When the course select pointer is set on the coupled side HSI using the
CRS knob on the GC, the course select error signal is established. This
signal represents the difference between actual aircraft heading and
the selected aircraft course.
The course error signal is routed from the IAC’s SG to the IAC’s flight
control function.
The radio deviation signal is routed from the navigation receiver to the
electronic flight instrument system (EFIS), and then to the flight control
function where the signal is lateral gain programmed.
