VOR NAVIGATION (NAV) MODE
The VOR mode automatically intercepts, captures, and tracks a
selected VOR radial, using the selected navigation source displayed on
the HSI. The navigation source displayed on the HSI is a function of the
NAV source buttons located on the display controller (DC). Table 8--1
is the procedure used to engage the VOR NAV mode.
