9.1 AUX PAGE GROUP
Section 3.1 introduced the GNC 420’s main page
groups (Table 9-1)—NAV, WPT, AUX, NRST—and
described each page in the NAV group. The third page
group (AUX) allows the pilot to change unit settings. The
AUX pages (Figure 9-1) also provide trip planning, fuel
planning, density altitude, true airspeed, and winds aloft
calculations.
