TEST Pushbutton
Pressing and holding the TEST pushbutton for 2 seconds will cause
the MLS radio to be tested. Pressing this pushbutton for less than
2 seconds is the same as not pressing it at all. The CDU will
display "TST" in the channel display during the time period that
the radio is being tested and until the radio test results have
been reported. The test is performed only when the pushbutton is
being held. The test shall terminate and the MLS CDU should
function normally if the pushbutton is released or after 30
seconds, whichever occurs first.
The alphanumeric channel/ident display is used for displaying the
results of the radio test.
If the MLS radio passes the test the
MLS CDU will display "OK".
If
the
MLS radio fails its test then
the MLS CDU will display "ERR".
The azimuth and glidepath displays will be blanked when in the TEST
mode.
