*11. Loose or foreign objects-Check.

Loose or foreign objects in the cockpit

can cause entanglement or obstruction

with critical controls (e.g., ejection

handle, stick, rudder pedals, throttle,

canopy handle, etc.).

BEFORE STARTING ENGINE

1. MAIN PWR switch-BATT.

To prevent possible depletion of bat

tery power, do not allow MAIN PWR

switch to remain in BATT or MAIN

PWR for more than 5 minutes without

engine running or external power

applied.

NOTE

A JFS RUN light flashing once per

second indicates a noncritical failure

in the JFS system. If the JFS operates

normally for engine start, the mission

may be continued. Notify maintenance

after flight.

A JFS RUN light flashing twice per

second indicates a critical failure in

the JFS system. The JFS will not

operate. Place the MAIN PWR switch

to OFF and notify maintenance.

Verify FLCS RLY light on.

NOTE

Toe brakes are not available when the

FLCS RLY light is on and the aircraft

battery is the only operating power

source.

PX III

Labored breathing through the

oxygen mask before engine start is

possible with the diluter lever in

NORM. It is not possible to to breath

through the oxygen mask before

engine start with the diluter lever in

100%.

2. FLCS PWR TEST switch-TEST and hold.

Activation of the FLCS PWR TEST switch

with the MAIN PWR switch in BATT closes

FLCS relays and allows verification of

power output of the FLCC with the aircraft

battery as the power source.

Verify lights on:

ACFT BATT TO FLCS.

FLCS PMG.

FLCS PWR (4).

Verify FLCS RLY light off.

3. FLCS PWR TEST switch-Release.

4. MAIN PWR switch-MAIN PWR.

Verify lights on:

ELEC SYS.

HYD/OIL PRESS.

FLCS RLY.

SEC.

ENGINE.

Do not apply external electrical power

for more than 30 minutes without

cooling air; longer operation may

damage electronic components which

cannot be turned off. Prior to applying

external power without cooling air,

insure that all avionic equipment is

off; UHF radio operation on backup

control is permissible.

T.O. GR1F16CJ1

NOTE

If FLCS RLY light is off, cycle MAIN

PWR switch to BATT and back to

MAIN PWR to open FLCS relays.

5. EPU GEN and EPU PMG lights-Confirm

off.

If either light is illuminated, turn the

MAIN PWR switch to OFF. Insure that

the EPU safety pin remains installed

and notify maintenance. (The EPU

will activate using hydrazine if the

EPU safety pin is removed.)

6. Communications-Established.

7. Canopy-As desired.

A failure of the canopy actuator

could allow the canopy to fall during

transit. Keep hands and arms out of

the path of canopy travel during

opening or closing.

To prevent possible engine damage,

stow or secure loose cockpit items prior

to engine start with the canopy not

closed.

When lowering or raising the

canopy handle, insure that the canopy

switch is not bumped to the up (open)

position before handle is completely

locked or unlocked. If this occurs, hold

the switch in the down (close) position

as soon as possible to relieve the

jammed condition and prevent canopy

actuator motor burnout. If required,

manually crank canopy toward the

closed position to relieve the jammed

condition. If possible, place MAIN

PWR switch to OFF and have the

aircraft battery disconnected by the

ground crew. This action removes

power from the canopy actuator.

8. Chocks in place, fireguard posted, and intake

and other danger areas clear (ground crew).

STARTING ENGINE

PW 229

Refer to figure 28 for danger areas. Moving the JFS

switch to either start position closes the FLCS

relays. The FLCS RLY light goes off; the FLCS PMG

light (and ACFT BATT TO FLCS light if engine is

started on battery power) illuminates. Toe brakes

also become functional (if engine is started on

battery power).

The JFS RUN light comes on within 30 seconds; after

the JFS RUN light illuminates, engine rpm starts to

increase smoothly. At approximately 15 percent

rpm, the hydraulic and fuel pressures increase. The

SEC caution light goes off by approximately 18

percent rpm. The throttle should be advanced to

IDLE after engine rpm reaches 20 percent.

Immediately after advancing the throttle to IDLE,

the SEC caution light illuminates for about 3

seconds to indicate automatic DEEC/SEC ground

selftest. Engine lightoff occurs within 20 seconds

after throttle advance and is indicated by airframe

vibration and an increase in rpm followed by an

increase in FTIT. Without external power connected,

only the RPM and FTIT indicators function until the

standby generator is on line.

At approximately 50 percent rpm, the JFS automati

cally shuts down. At approximately 55 percent rpm,

the standby generator comes on line, the ENGINE

warning light goes off, and the OXY LOW warning

light illuminates for approximately one second. To

insure the emergency buses are being powered by the

standby generator, check for illumination of the

SEAT NOT ARMED caution light and three green

WHEELS down lights prior to the main generator

coming on line. Five to ten seconds after the the

standby generator comes on line, the main generator

comes on line, and the standby generator goes off line.

FTIT increases smoothly at a moderate rate and

normally peaks at less than 625

1. JFS switch-START 2.

2. SEC caution light-Check off.

T.O. GR1F16CJ1

3. Throttle-Advance to IDLE at 20 percent

rpm minimum.

If the FUEL MASTER switch is

discovered in OFF during start (i.e.,

after the throttle is moved to IDLE),

discontinue the start. Positioning the

FUEL MASTER switch to MASTER

with the throttle out of OFF may cause

a hot start or tailpipe fire.

NOTE

If the HYD/OIL PRESS warning light

goes off and stays off prior to

approximately 25 percent rpm, sus

pect failure of the engine oil pressure

sensor and abort the aircraft. This

check is not valid if less than 30

seconds elapse from movement of the

MAIN PWR switch out of OFF until

both hydraulic pressures are above

1000 psi (i.e., low oil pressure time

delay has not expired; in which case,

the HYD/OIL PRESS warning light

goes off when hydraulic pressures

exceed 1000 psi, but may reilluminate

if the 30second time delay expires

while oil pressure is still low.

If the main and/or standby generator

fails to come on, do not attempt reset.

Although the generator(s) may reset, a

problem may still exist. Notify

maintenance.

The SEC caution light illuminates

immediately after throttle advance for

about 3 seconds indicating automatic

DEEC/SEC ground selftest.

If the FLCS RLY light remains on with

the JFS switch in either start position,

one or more FLCS relays did not latch

closed. Latching may occur when the

standby or main generator comes on

line. If the FLCS RLY light goes off

when either generator comes on line,

notify maintenance of the occurrence

after flight. If the FLCS RLY light

remains on after the main generator is

on line, notify maintenance.

If an engine restart is desired shortly

after engine shutdown, motor the

engine with the JFS for a minimum of

1 minute or a maximum of 4 minutes

before throttle advancement to insure

the FTIT drops below 200

C. Initiat

ing a start with the FTIT above 200

may result in a DEEC FTIT limited

hung start.

4. ENGINE warning light-Off (approxi

mately 55 percent rpm).

*Engine at idle and check:

5. JFS switch-Confirm OFF.

If JFS switch does not automatically

return to OFF, turn JFS off. Notify

maintenance after flight.

6. HYD/OIL PRESS warning light-Off.

The HYD/OIL PRESS warning light may

not go off until rpm is increased to 70

percent. If the warning light comes on again

at idle, notify maintenance.

7. FUEL FLOW - 5001500 pph.

8. OIL pressure-15 psi (minimum).

9. NOZ POS-Greater than 80 percent.

10. RPM-6577 percent.

11. FTIT-625

C or less.

12. HYD PRESS A & B-28503250 psi.

13. Six fuel pump lights (ground crew)-On.

NOTE

FFP light may blink at idle rpm.

T.O. GR1F16CJ1

14. Main fuel shutoff valve (ground crew)- Check.

Do not make stick inputs while ground

crew is in proximity of control surface.

15. JFS doors (ground crew)-Verify closed.

16. Throttle cutoff release-Check.

Verify that the cutoff release does not

remain in the actuated position by attempt

ing to retard the throttle to OFF without

depressing the cutoff release. If throttle

moves to OFF, remain in OFF and notify

maintenance.

NOTE

Failure to perform this check after

engine start can result in an unde

tected stuck throttle cutoff release,

which may lead to an unintentional

engine shutdown.

STARTING ENGINE

129

Refer to figure 28 for danger areas. Moving the JFS

switch to either start position closes the FLCS

relays. The FLCS RLY light goes off; the FLCS PMG

light (and ACFT BATT TO FLCS light if engine is

started on battery power) illuminates. Toe brakes

also become functional (if engine is started on

battery power).

The JFS RUN light comes on within 30 seconds; after

the JFS RUN light illuminates, engine rpm starts to

increase smoothly. The throttle should be advanced

to IDLE after engine rpm reaches either 20 percent

rpm (ambient temperature less than 90

F) or

maximum motoring rpm (ambient temperature

F or greater). Engine lightoff occurs within 10

seconds after throttle advance and is indicated by an

airframe vibration and an increase in rpm followed

by an increase in FTIT. Without external power

connected, only the RPM and FTIT indicators

function until the standby generator is on line.

The SEC caution light goes off at 20 percent rpm. At

approximately 55 percent rpm, the JFS automati

cally shuts down. At approximately 60 percent rpm,

the standby generator comes on line and the

ENGINE warning light goes off. To insure the

emergency buses are being powered by the standby

generator, check for illumination of the SEAT NOT

ARMED caution light and three green WHEELS

down lights prior to the main generator coming on

line. Five to ten seconds after the standby generator

comes on line, the main generator comes on line and

the standby generator goes off line.

FTIT increases smoothly at a rapid rate.

1. JFS switch-START 2.

NOTE

Abnormal rpm indications (i.e. instan

taneous jumps) may indicate alterna

tor failure and not rpm indicator

malfunction. Abort the aircraft and

notify maintenance.

2. Throttle-Advance to IDLE at either 20

percent rpm minimum (ambient tempera

ture less than 90

F) or maximum motoring

rpm (ambient temperature 90

F or greater).

If the FUEL MASTER switch is

discovered in OFF during engine start

(i.e., after the throttle is moved to

IDLE), discontinue the start. Position

ing the FUEL MASTER switch to

MASTER with the throttle out of OFF

may cause a hot start or tailpipe fire.

NOTE

If the HYD/OIL PRESS warning light

goes off and stays off prior to

approximately 15 percent rpm, sus

pect failure of the engine oil pressure

sensor and abort the aircraft. This

check is not valid if less than 30

seconds elapse from movement of the

MAIN PWR switch out of OFF until

both hydraulic pressures are above

1000 psi (i.e., low oil pressure time

delay has not expired; in which case,

when either generator comes on line,

notify maintenance of the occurrence

after flight. If the FLCS RLY light

remains on after the main generator is

on line, notify maintenance.

3. SEC caution light-Off.

4. ENGINE warning light-Off (approximately

60 percent rpm).

NOTE

In hot day conditions (temperature

greater than 90

F (32

C)) the EN

GINE warning light may not go off

until idle speed is obtained (greater

than 70 percent rpm).

*Engine at idle and check:

5. JFS switch-Confirm OFF.

If JFS switch does not automatically

return to OFF, turn JFS off. Notify

maintenance after flight.

6. HYD/OIL PRESS warning light-Off.

The HYD/OIL PRESS warning light may

not go off until rpm is increased to 70

percent. If the warning light comes on again

at idle, notify maintenance.

7. FUEL FLOW- 7001700 pph.

8. OIL pressure-15 psi (minimum).

9. NOZ POS-Greater than 94 percent.

10. RPM-6280 percent.

11. FTIT-650

12. HYD PRESS A & B-28503250 psi.

13. Six fuel pump lights (ground crew)-On.

NOTE

FFP light may blink at idle rpm.

14. Main fuel shutoff valve (ground crew)-Check.

Do not make stick inputs while ground

crew is in proximity of control surface.

15. JFS doors (ground crew)-Verify closed.

16. Throttle cutoff release-Check.

Verify that the cutoff release does not

remain in the actuated position by attempt

ing to retard the throttle to OFF without

depressing the cutoff release. If throttle

moves to OFF, remain in OFF and notify

maintenance.

NOTE

Failure to perform this check after

engine start can result in an unde

tected stuck throttle cutoff release,

which may lead to an unintentional

engine shutdown.

Engine vibration/rumble may be

sensed on the ground while accelerat

ing or decelerating the engine, when

transferring to SEC, or when stabi

lized at idle in either PRI or SEC. This

vibration/rumble has no adverse effect

on the engine or aircraft structure. The

vibration/rumble should disappear

when the throttle is advanced slightly

(approximately 5 percent rpm increase).

AFTER ENGINE START

1. TEST switch panel-Check:

a. PROBE HEAT switch - PROBE HEAT.

PROBE HEAT caution light off. If the

caution light illuminates, one or more

probe heaters are inoperative or a

monitoring system failure has occurred.

b. PROBE HEAT switch - TEST.

PROBE HEAT caution light flashes 35

times per second. If the caution light

does not illuminate or if it illuminates

but does not flash, the probe heat

monitoring system is inoperative.

c. PROBE HEAT switch - OFF.

d. FIRE & OHEAT DETECT button-Test.

T.O. GR1F16CJ1

212Change 1

PX II

OXY QTY test switch-Test and

check.

f. MAL & IND LTS button-Test.

NOTE

Proper VMS operation is verified by

the presence of each word in priority

sequence (i.e., PULLUP, ALTITUDE,

WARNING, etc.). A brief LG warning

horn is also heard prior to the

WARNING and CAUTION words.

Only the LG warning horn and the

warning and caution voice messages

are heard when MAL & IND LTS test

is initiated from the rear cockpit.

LESS

b7n

PX III

The circuitry

powering the AVIONICS FAULT cau

tion lights and ECM lights is not

capable of turning on both the

and

the

lights except during MAL &

IND LTS test. As a result, the only time

these lights illuminate in either

cockpit is during MAL & IND LTS test.

For avionics faults, failure of the

AVIONICS FAULT caution lights to

come on also prevents illumination of

the MASTER CAUTION light and

operation of the voice caution message.

Faults will still be displayed on the

PFLD. The interim solution is removal

of the light bulbs from the

AVIONICS FAULT caution light and

ECM light. This solution enables

operation of the

AVIONICS FAULT

caution light,

ECM light, both

MASTER CAUTION lights, and the

voice caution message after a fault

occurs. The

AVIONICS FAULT

caution light and

ECM light should

not illuminate during MAL & IND LTS

test if the bulbs have been removed. If

the

AVIONICS FAULT caution

light or

ECM light illuminates

during MAL & IND LTS test, contact

maintenance.

c. MFD switch-MFD.

d. UFC switch-UFC.

e. GPS TRK switch-GPS TRK.

4. EGI/INS-Align (

PX III

after display visible

on the DED).

NOTE

PX III

If GPS is unavailable, failure to

enter alignment coordinates flags the

alignment as degraded (NAV RDY

light does not flash).

PX II

Entry of alignment coordinates is

required even if internal coordinates

are exactly equal to parking spot

location.

Failure to enter alignment coordinates

flags the alignment as degraded (NAV

RDY light does not flash).

5. SNSR PWR panel:

a. LEFT HDPT switch-OFF, unless

required.

Select OFF unless TFR/FLIR opera

tion is planned. With LEFT HDPT

power on and the TFR in OFF/STBY, a

failure in the WX mode circuitry can

cause the TFR to operate in the WX

mode. An unexpected flyup may

subsequently occur.

b. RIGHT HDPT switch-As required.

c. FCR switch-FCR.

In environments of high humidity,

delay turning the FCR on for approxi

mately 4 minutes. This action pre

cludes damage to FCR caused by

moisture in the ECS immediately after

engine start.

d. RDR ALT switch-RDR ALT.

C & I knob-UFC.

NOTE

If UFC battery failure occurs, UHF/

VHF preset frequencies in the UFC

revert to default values until entered

manually or by the DTC.

8. MFL-Clear.

NOTE

Multiple nonresettable FLCS MFL's

may occur during engine start and may

be accompanied by a lack of control

surface response to stick/rudder com

mands. These MFL's can occur if

aircraft battery voltage is low or if a

switching problem occurs when the JFS

switch is moved out of OFF. If multiple

FLCS MFL's remain after a FLCS reset:

b1q

Perform the following:

DBU switch-BACKUP, then OFF.

Cycling the DBU switch with

WOW reinitializes the FLCC and

inhibits FLCS MFL reporting for

20 seconds.

If FLCS MFL's clear and do not recur

after 20 seconds, maintenance action

is not required.

LESS

b1q

Perform the following:

DBU switch - BACKUP, then OFF.

FLCS RESET switch - RESET.

If FLCS MFL's clear, maintenance

action is not required.
If FLCS MFL's remain:

FLCS BIT - Initiate and monitor.

If FLCS MFL's remain:

Engine - Shut down, then restart to

cycle power to the FLCC.

If FLCS MFL's clear following FLCS BIT

or engine restart, notify maintenance of

the occurrence after flight.
