.
RMIs
Observe warning flags are out of view. Synchronize the compass system by observing the polarity indicated by each SYNC annunciator indicating in the mid position.
.
HSIs
Observe warning flags are out of view. Verify the opposite HSI indicates the same heading.
.
Vertical Speed Indicators
Observe off flag is not in view and pointer is indicating
approximately zero.
.
Standby Altimeter/Airspeed Indicator
Rotate the baro set knob until desired settings are in MB/IN HG readouts, observe indications are normal. Observe airspeed indicator for normal indication.
.
Standby Compass
Check standby compass indication to be within 10 degrees of other compasses.
.
Clocks
Check and set the clocks to universal coordinated time.
OTHER FLIGHTS
.
Verify altimeter settings are current. The barometric altimeter
internal bug may be set to single engine acceleration altitude.
.
Verify ADIs and standby horizon are erect and level.
.
Verify no warning flags appear in flight instruments.
TRI (FLOW) .................................................................................CHECKED
FIRST FLIGHT OF DAY
Push the test button and observe PLUS 12 is displayed in the RAT readout and 2.04 is displayed in EPR LIM readout. All lights, including the NO MODE light should be out. Release the test button, the thrust rating indicator will display the ambient temperature, the EPR will display a fail flag and 2.00 EPR. The mode selector lights will be out and the NO MODE light will be on. Push the T.O. button and observe the NO MODE light goes out, T.O. button light is on, and a valid EPR is displayed.
Note: For JT8D-217 engines, a valid TRI test should indicate + 12° and 1.94 EPR.
Note: The thrust rating indicator will display NO MODE for the following reasons:
.
Initial power turn on.
.
Power interrupts greater than 200 milliseconds.
.
DFGS detected failure of computation or input sensor.
.
Mode mismatch. The NO MODE annunciation will be accompanied by the value
2.00 displayed in the EPR Lim readout with the flag in view.
OTHER FLIGHTS
No test is necessary.
Engine Reverse Thrust Lights (FLOW)................................................OUT
FIRST FLIGHT OF DAY
Check both ENG REVERSE THRUST lights and both REVERSE UNLOCK lights are out. All engine reverse levers must be fully down. However, if the systems have been depressurized by the maintenance crew, the REVERSE ACCUMULATOR LOW lights may be on and hydraulic pressure must be provided to recharge the accumulators.
Caution: If ENG REVERSE THRUST or REVERSE UNLOCK lights are on, the reversers could be extended. Therefore, it is necessary to obtain ground clearance before pressurizing the hydraulic system.
OTHER FLIGHTS
Same as FIRST FLIGHT OF DAY.
Engine Instruments ......................................................................CHECKED
FIRST FLIGHT OF DAY
Check EPR, N1, EGT, N2, oil pressure, and oil temperature gauges for
normal, static indications.
Check oil quantity. It is recommended to have at least 5 quarts before starting and at least 12 quarts when engines stabilize at idle RPM. After the engine has operated at idle for a short period of time, the oil quantity should indicate 12 quarts minimum to 16 quarts maximum. If during engine start, the oil quantity reads in excess of 16 quarts, the engine should be shut down and checked for either over servicing or a faulty quantity gauge.
OTHER FLIGHTS
Same as FIRST FLIGHT OF DAY.
Gear Lever, Horn, Lights (FFOD) .......... DOWN, CHECKED, 3 GREEN
FIRST FLIGHT OF DAY The landing gear handle can be pulled aft while in the DOWN position. This will turn off the green lights, turn on the red lights, and if either throttle is at idle, the horn will sound. The GEAR HORN OFF button can then be pushed to check the silencing circuit provided the flaps are not extended beyond the takeoff position. When the landing gear handle is released into the DOWN detent notch, the red lights will go out and the green lights will come on.
Note: If the aural warning does not sound during the test, continue holding out and down on the landing gear handle while advancing the throttles to the takeoff position and returning them to the idle stop. The aural warning should sound when the throttles are returned to the idle stop.
