course line (CRS) is selected on the

course deviation commensurate with
the CDI scaling on the HSI display. The

deviation from the selected course is
within one degree with TACAN steering.
With waypoint or waypoint offset
steering selected, the dots are removed
when course deviation is less than 0.4
nm, gear up, or 0.03 nm, gear down.
When ILS needles are shown on the
ADI display, they are also displayed on
the HUD. The ILS needle scaling is
commensurate with the scaling on the
ADI display. The needles will flash
when limited.
