4.4.4. Ground Test
Ground Test initializes the system for on-the-ground testing. In this configuration, the barometric
altimeter is simulated to 50,000 ft, heading simulated to 0 degrees, and the radar altimeter simulated to
2,500 ft.
NOTE
Ground test is available only if the squat switch input indicates aircraft is on the ground.
Ground test (see figure 4-17) is accessed by selecting that option from the Service Menu (i.e., press
SELECT with Ground Test highlighted). To access ground test with a terminal device use the Ground
Test command.
Figure 4-17. Ground Test
If the system detects a heading fault, HDG will be displayed in the bottom center portion of the screen.
The buttons perform the following operations in this mode:
• EXIT - causes the system to return the System Data Menu (figure 4-6).
• Soft-key (2) toggles the system through the above (ABV), normal (NRM), and below (BLW)
altitude display modes. It is labeled to indicate current mode (i.e., ABV, NRM, or BLW).
• Soft-key (3) toggles the display range between 2 and 6 nm. It is labeled to indicate current
range (i.e., 2nm or 6nm).
• Soft-key (4) is not used.
