Mode S and ATCRBS Transponder
XPDR Auto-Test:
Every parameter the user commonly needs to view is displayed on one
screen.
The auto-test performs all tests defined by FAR Part 43 Appendix F,
including the proposed Eurocontrol additional tests.
The tests are tailored automatically according to reported transponder
level to avoid erroneous failures.
The test list is selected from the auto-test screen. This provides an
easy means of selecting any of the individual tests that comprise the
auto-test.
Tests on the 2nd screen (not shown) include:
13 UF21
14 UF24
15 ELEMENTARY SURVEILLANCE 1
16 ELEMENTARY SURVEILLANCE 2
17 ENHANCED SURVEILLANCE
Individual tests may be reviewed for failures which are identified by
an arrow symbol.
User selects config required for test.
If the class of the transponder is unknown, the generic config may be
selected which applies to the widest limits.
The test set will automatically determine the Mode S transponder
level.
The selected config parameters may be displayed by pressing the
INFO softkey.
Eight predetermined configs are provided to meet the currently fielded
transponder test needs.
The Eurocontrol Elementary Surveillance DAP's (Downlink Aircraft
Parameters) are displayed on two screens.
Eurocontrol Enhanced Surveillance DAP’s are displayed on one
screen.
