MK XXII EGPWS Installation Manual

to continue from level-to-level, the ST button must also be ‘pressed and held’ for more than 0.5 seconds, but less than 2 seconds, which is identical to the Short Cancel function.

Therefore, for simplicity, the phrase “Press ST Button” in the verification procedure means to press and hold the ST button for more than 0.5 seconds, but less than 2 seconds. The procedure guides the operator directly to ST Level 3, “System Configuration”, skipping most of ST Level 1 and Level 2.

To verify the Regional Terrain Database that was just loaded into the EGPWC, perform these steps:

NOTE: ‘On the Bench’, this test requires an audio speaker and a self test button.

(1)Ensure the EGPWC power is ON

(2)Press ST button to initiate ST Level 1.

(3)After ST Level 1 message starts, Press ST button to cancel Level 1 and start Level 2.

(4)After ST Level 2 message, “Current Faults”, is heard,Press ST button to cancel Level 2.

(5)When the message, “Press to Continue”, is heard,Press ST button to start ST Level 3.

(6)Verify the Terrain Database version annunciated in the following sequence:

a)SYSTEM CONFIGURATION

b)PART NUMBER 965-1590-XXX

c)MOD STATUS XX

d)SERIAL NUMBER XXXX

e)APPLICATION SOFTWARE VERSION XXXXX

f)TERRAIN DATABASE VERSION XXXX

The following example of Terrain Database Version annunciation: “424NAM” (for NORTH AMERICA), “424EUR” (for EUROPE), or “424PAC” (for PACIFIC). Other versions will follow the same pattern.

(7)Other messages that follow the Terrain Database Version can be ignored. When ST Level 3 finishes, the message “Press to Continue” is heard. If the ST button is not pressed again the ST sequence terminates.

NOTE: If power was connected to the EGPWC per steps B1 through B4, perform shut-down per steps (7) and (8) following.

(8)Turn Power Supply OFF.

(9)Disconnect Power leads from the EGPWC.
