Test

JOINT ADVANCED MULTI-ENGINE T-44A

is centered. Maximum split between pilot needle and CDI should be 4. Pilot rotates 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.

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. If not available, compare to the radial and DME indicated during the VOR checks.

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

to a ground checkpoint.

A typical report would be:

(Pilot)"TACAN needle indicates 196, CDI centered on 195.

DME indicates 0.5."

(CP)"TACAN needle indicates 195."

NOTE: CP's CDI and "to-from" indicator is never functional in TACAN.

(4). Test

Pilot presses TEST pushbutton on TACAN control panel on pedestal. Pilot and CP verify

TACAN needle pointing 180 (+ 2). Pilot verifies DME top row reads 0.0 or 0.1 and bottom

row reads all 8's. Pilot releases TEST pushbutton and notes DME top row reads all 8's.

NOTE: If the TACAN panel TEST switch is inoperative, utilize the TEST switch on the DME readout panel. The

system check is identical using either switch.

NOTE: DME test readout usually returns to normal in approximately 12 seconds.

A typical report would be: (pilot)"TACAN needle indicates 181. DME 0.1, all 8's."

(CP)"TACAN needle indicates 180."

g. ADF:

(1). Tune

Pilot ensures ADF switch is on, TONE pushbutton is out, and ADF pushbutton is

depressed. Pilot presses ADF button on CDPU and tunes 0382 (CONNOR LOM). Press USE

and note 0382 displayed in ADF 1 RRU.

NOTE: NDBs used for navigation normally range from 190 to 535 kHz. The ADF is capable of receiving

frequencies up to 1749, such as commercial radio stations. Four digits are required input for all stations.

Therefore, navigation frequencies must be entered with a zero preceding the 3-digit number.

(2). Identify

Verify ID and adjust volume as required.

(3). Navigate

Pilot selects ADF needle on RMI (single needle, left pushbutton). CP also selects ADF

needle on RMI (single needle, left pushbutton).

Pilot and CP verify ADF needles point to CONNOR (approximately 290 to 300 degrees).

(4). Test

P presses ADF TEST pushbutton on MSU. Pilot and CP verify ADF needles rotate

counterclockwise 90 and stop. Release pushbutton and verify both needles return to correct

bearing. Movement should be positive and without ratcheting.

NOTE: The ADF will not test (needle remains parked at 270-090) if an NDB is not received or if the ADF

pushbutton is not depressed.

Pilot and CP return RMI needles to VOR.
