Figure 2-19. AHRS/AIR DATA INPUT Page
This page shows real time data from the GRS 77 (AHRS 1) and GDC74A (Air Data1). The aircraft is not
equipped with a second GRS 77 or GDC74A, so the AHRS 2 and Air Data 2 fields will remain blank. If the
AHRS 1 or Air Data 1 fields are blank, the units are not online and the cause should be determined.
