JOINT ADVANCED MULTI-ENGINE T-44A
Depress VOR/ILS and GPS/NAV push buttons on FD SEL panel (beneath P's HSI).
Confirm green VOR/ILS and NAV lights on respectively.
Tune NAV 1
U-U WPT 6- 111.3 (ILS/DME RWY 13R at Navy Corpus). Note the localizer frequency in NAV 1
RRU. The VOR 1 needle will remain parked at the 90-270 position (azimuth is never available in
localizer). DME is received from the NGP VOR frequency (WPT 1).
NOTE: The localizer frequency for the ILS in use at NGP should be stored in WPT 6. Any localizer frequency
(108.10-111.95) could be used to self-test the ILS system, however the NGP localizer is normally used for
training. For localizer, VOR, or TACAN self-test, the frequency selected does not have to be received. It is
strictly an internal test of the equipment.
Tune NAV 2
Enter any localizer frequency (generally the same frequency used in NAV 1). Note the localizer
frequency in NAV 2 RRU. The VOR 2 needle will remain parked at the 90-270 position (azimuth is
never available in localizer). No ID is available since the station is too distant to receive.
Not required since only an internal test is performed.
Not applicable for a localizer.
P places MKR BCN mixer switches up one at a time and selects LO sensitivity. CP places
MKR BCN switches up one at a time and selects High sensitivity.
P presses NAV TEST pushbutton on MSU. P and CP verify marker beacon one and two
audio and adjust volume, then place both MKR BCN switches OFF. P and CP verify O/M/I
lights illuminated, a 1½ unit down display on the GS 1½ unit right display on the CDIs.
A typical report would be "One and a half down and right ." CP reports any discrepancies.
(1). Store Waypoints
WPT 1-114.0 (NGP)-PRE
WPT 2-115.5 (CRP)-PRE
(2). Tune NAV 1.
D-U-D Waypoint 1. Note 114.0 in NAV 1 RRU.
Ensure OPER/STBY switch is in OPER. If the system is in STBY, it will show dashed
lines in the DME readout.
(3). Tune NAV 2
Enter 114 into NAV 2. Note 114.0 in NAV 2 RRU.
Verify ID on VOR 1 and VOR 2 and adjust volume as required.
