Takeoff Checklist - Cont'd

JOINT ADVANCED MULTI-ENGINE T-44A

Top arc has light shading.

Mode Wx ALERT

Confirm test pattern center band alternates dark/bright 4 times per scan.

Mode Wx GAIN MAX

Confirm strobe line (antenna position) moves across screen a full 90 without jumping.

HOLD/SCAN HOLD

Confirm strobe line disappears and display freezes.

WARNING

Prior to moving from TEST position, P scans for any large metal objects within 50 feet, personnel within 18 feet,

or in the vicinity of refueling operations. If personnel, vehicles, or aircraft approach, P immediately selects TEST

or STBY.

Function 20

Mode Wx

l..

HOLD/SCAN SCAN

m. Tilt/BRTVary brightness and tilt (0-15 degrees) and confirm that ground clutter appears at

lower settings and weather (if any) appears at higher settings. Re-attempt using 5 or 10 if a

satisfactory check is not obtained on 20-mile scale.

FunctionOFF or STBY

NOTE: Full operation of this radar system is possible approximately 2 minutes after turn-on. Because of the fast

warm-up capability, if no significant weather is in the immediate area, the P should elect to leave the function

switch OFF after system warm-up and test rather than in STBY to prolong the life of the magnetron transmitting

tube.

NOTE: Radar checks cannot be practiced in the simulator.

13. FLIGHT INSTRUMENTS

"CHECKED" (P, CP)

P and CP check flight instruments for proper indications:

Airspeed Less than 40 kts.

RMI/HIS Report headings (should be within 5 of each other); no abnormal flags.

Turn/slip Needle erect, ball centered, no flag.

Flight Director

Press and hold TEST. Note indication of 10 (+3) of:

(1)

Pitch down

Roll left

Compass slew

ATT and HEADING flags displayed.

(2) Release TEST and note attitude gyro returns to wings level, on the horizon, no abnormal flags,

and headings are correct.

IVSI/VSI Approximately zero.

A typical response would be: (P) "Airspeed less than 40, my RMI, your HSI 130, my HSI, your

RMI 128, turn needle erect, ball centered, 10, 10, 10, and 2, VSI zero." CP reports any

discrepancies.
