The system will automatically slew the localizer course pointer to the correct final approach course when an ILS, localizer, back course, LDA, or SDF approach is active in the external navigator.
The flight had been cleared for an approach at Ketchikan but flew past the inbound localizer course.
I was able to fly the GPS-derived localizer course with the step-downs all the way to the missed approach point with acceptable precision.
The transition gets the aircraft from the en route phase to the localizer course by radar vector, DME arc, transition fix, ADF, procedure turn, holding pattern, vectors or other maneuvers.
On navigators with an ILS receiver, the navigator will automatically switch from GPS to VLOC mode when the aircraft gets close to the localizer course.
Recall that unlike a VOR, the localizer course you set is irrelevant to CDI behavior; the CDI merely indicates your relationship to the localizer regardless of the course setting.
As it approached the Blue Ridge Airport, ATC cleared the King Air to hold "as published" on the localizer course at 4000 feet.
Because of the proximity of the VOR to the airport, it may be easy to assume that an appropriate lead radial may be a couple radials shy of the reciprocal to the localizer course.
An obvious odd-ball with this approach is the localizer course drives right through Restricted Areas R-4001 B.
This concept has been with us for decades and may actually be enforced by some flight examiners who have never flown a Lear at 250 knots on an arc to a three-degree-wide localizer course.
