NOTE
An all-angle intercept after receiving radar vectors may
be accomplished by deactivating HDG mode (defaulting
to ROL) just prior to pressing the APR button. The HDG
bug must still be positioned to agree with the OBS
course to provide course datum to the autopilot, but the
airplane will continue to track approximately the last
heading until intercept.
4. If the Course Deviation Indicator (CDI) needle is greater than 2
to 3 dots from the center: the autopilot will annunciate
APRARM; when the computed capture point is reached the
ARM annunciator will go out and the selected course will be
automatically captured and tracked.
5. If the Course Deviation Indicator (CDI) needle is less than 2 to
3 dots from the center: the HDG mode will disengage upon
selecting APR mode; the APR annunciator will illuminate and
the capture/track sequence will automatically begin (after 5
seconds alotted to position the HDG bug to agree with the
desired approach course).
