JOINT ADVANCED MULTI-ENGINE T-44A

Navigate

(1). Ensure P and CP RMI needles (both needles) are selected to VOR.

(2). P and CP call their respective VOR 1 and VOR 2 needle courses indicated on the RMI. The

needles should point to the station with a max split of 4. P and CP then center their CDIs, with the

pointer toward the VOR. Note "to-from" flag pointing "to." P and CP call course indicated when

CDI is centered. Maximum split between needles and CDIs should be 4. P and CP rotate course

selector left and right of the centered CDI.

CDI should reach full deflection at 10 in each direction. Continue rotating course selector and note

"to-from" flag change to "from" as selector passes approximately the 90 position.

(3). Ensure the DME is indicating correctly. DME usually reads between 0.2 and 1.0 at most points

on the surface at NGP. Compare the radials and DME to a ground checkpoint if available. DME

should be within + 0.5 NM or 3% of actual distance to the NAVAID, when compared to a ground

check point. If the DME is not indicating correctly, ensure DME indicator is selected KTS or MIN

with brightness adjusted. If DME is selected OFF or brightness is too low, the display will be blank.

A typical report would be:

(P) "VOR needles indicate 196, CDI centered on 195. DME indicates 0.5."

(CP) "VOR needles indicate 195, CDI centered on 196."

Test

P presses NAV TEST pushbutton on MSU. P and CP verify O/M/I lights illuminated and

compare VOR 1 /VOR 2 needles. Indications should be 003 (+2).

A typical report would be:

(P) "VOR needles indicate 004 degrees."

(CP) "VOR needles indicate 003 degrees."

MKR BCN 1/MKR BCN 2:

Previously tested during localizer checks.

TACAN:

(1). Tune

Press TACAN on FD SEL panel. Note green TACAN light illuminated on FD SEL panel

and NORMAL light illuminated on TACAN SEL panel. Ensure GPS/NAV push button is

selected to NAV.

Ensure OPER/STBY switch is in OPER.

Tune channel 87 (NGP). Ensure X is selected.

NOTE: The vast majority of TACAN stations are in the X band. Only a few sites, such as Vandenberg AFB,

utilize Y.

(2). Identify

Verify ID and adjust volume as required.

NOTE: TACAN identifications are broadcast approximately once each 37 seconds. If required, continue checks

while waiting for the ID.

(3). Navigate

P and CP call their respective magenta TACAN needle courses indicated on the HSI. The

needles should point to the station with a max split of 4. P then centers CDI, with the pointer

toward the TACAN. Note "to-from" flag pointing "to." P calls course indicated when the CDI
