3.1.3 Low Track (LO TRK) Mode, System Twenty / Thirty

Select the VOR frequency on the Navigation Receiver.  Maneuver the aircraft to

within 

±

1 CDI needle width and 

±

10

°

 heading of the selected course.  Engage

the low track mode.  The LO TRK lamp alone will be illuminated as shown

in Fig. 3-3, to acknowledge that this mode is engaged.  The autopilot will track

the  selected  course  with  minimum  authority,  thereby  ignoring  short  term  CDI

needle  deflections  (excursions)  to  inhibit  aircraft  scalloping  during  VOR

station  passage.
