An all-angle intercept after receiving radar vectors may be
accomplished by deactivating HDG mode (defaulting to AOL)
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.
