COWL VALVE OPEN lights - illuminated dim

COWL ANTI-ICE lights - extinguished

Note:If COWL VALVE OPEN lights remain illuminated bright

with engines at IDLE, position APU BLEED air switch to

OFF and increase thrust slightly (up to a maximum of

30% N1).

CAUTION: Avoid prolonged operation in moderate to severe icing

conditions.

Severe icing can usually be avoided by a change in altitude and/or

airspeed. If flight in moderate to severe icing conditions cannot be

avoided accomplish the following, on both engines, one engine at a

time at approximately 15 minute intervals:

Thrust

Increase

Increase thrust to a minimum of 80% N1 to ensure the fan blades and

spinner are clear of ice.

Engine vibration may occur due to fan blade/spinner icing. If engine

vibration continues after increasing thrust, accomplish the

following on both engines, one engine at a time:

ENGINE START switch

FLT

Thrust

Adjust

Adjust thrust to 45% N1. After approximately five seconds,

increase thrust lever slowly to a minimum of 80% N1.

Note:Engine vibration may reduce to a low level before 80%

N1 is reached, however, thrust increase must continue to

a minimum of 80% N1 to remove ice from the fan blades.

Note:Engine vibration may indicate full scale prior to shedding

ice; however, this has no adverse effect on the engine.

If vibration does not decrease, accomplish the procedure for HIGH

ENGINE VIBRATION “If not in icing conditions.”

Wing Anti-Ice Operation - Inflight

The wing anti-ice system may be used as a de-icer or anti-icer in flight only. The

primary method is to use it as a de-icer by allowing ice to accumulate before

turning wing anti-ice on. This procedure provides the cleanest airfoil surface, the

least possible runback ice formation, and the least thrust and fuel penalty.

The secondary method is to use wing anti--ice prior to ice accumulation. Operate

the wing anti-ice system as an anti-icer only during extended operations in

moderate or severe icing conditions, such as holding.

Ice accumulation on the flight deck window frames, windshield center post or on

the windshield wiper arm may be used as an indication of structural icing

conditions and the need to turn on wing anti-ice.

Normally it is not necessary to shed ice periodically unless extended flight through

icing conditions is necessary (holding).

CAUTION: Use of wing anti-ice above approximately FL350 may

cause bleed trip off and possible loss of cabin

pressure.

When wing anti-ice is required:

Note: Prolonged operation in icing conditions with the leading edge

and trailing edge flaps extended is not recommended. Holding

in icing conditions with flaps extended is prohibited.

Approach and Landing

Use normal procedures and reference speeds unless a flaps 15 landing

is planned.

If a flaps 15 landing will be made:

Set VREF 15

SP.16.9

Supplementary Procedures -

Adverse Weather

Boeing 737 Operations Manual

If any of the following conditions apply, set VREF ICE = VREF

15 + 10:

• engine anti-ice will be used during landing

• wing anti-ice has been used any time during the flight

• icing conditions were encountered during the flight and the

landing temperature is below 10° C.

Taxi-In and Park

If prolonged operation in icing conditions with the leading and trailing

edge flaps extended was required:

Flaps

Retraction to less than flaps 15 is not recommended until ice has been

removed or a ground inspection has been made.

After landing in icing conditions:

Stabilizer trim

Set 0 to 2 units

Prevents melting snow and ice from running into balance bay areas and

prevents the stabilizer limit switch from freezing. With flaps retracted,

this requires approximately eight hand wheel turns of manual trim.

WARNING: To avoid personal injury, ensure that the stabilizer

trim wheel handle is stowed prior to using electric

trim.

Engine anti-ice

As required

If icing conditions exist, engine anti-ice must be ON.

Hot Weather Operation

During ground operation the following considerations will help keep the airplane

as cool as possible:

• While the airplane is electrically powered, packs should be run or

cooling air supplied to the airplane when the OAT exceeds 40° C

(103° F) to protect the reliability of electrical and electronic

equipment in the airplane.

SP.16.11

Supplementary Procedures -

Adverse Weather

Boeing 737 Operations Manual

• If cooling air is available from an outside source, the supply should

be plugged in immediately after engine shutdown and should not

be removed until just prior to engine start.

• Keep all doors and windows, including cargo doors, closed as

much as possible.

• Electronic components which contribute to a high temperature

level in the flight deck should be turned off while not needed.

• Open all passenger cabin gasper outlets and close all window

shades on the sun-exposed side of the passenger cabin.

Brake temperature levels may be reached which can cause the wheel fuse plugs to

melt and deflate the tires. Consider the following actions:

• Be aware of brake temperature buildup when operating a series of

short flight sectors. The energy absorbed by the brakes from each

landing is accumulative.

• Extending the landing gear early during the approach provides

additional cooling for tires and brakes.

• In-flight cooling time can be determined from the “Brake Cooling

Schedule” in the Performance-Inflight section.

During flight planning consider the following:

• High temperatures inflict performance penalties which must be

taken into account on the ground before takeoff.

• Alternate takeoff procedures (No Engine Bleed Takeoff, Improved

Climb Performance, etc.)

Moderate to Heavy Rain

Flights should be conducted to avoid thunderstorm or hail activity by overflight or

circumnavigation. To the maximum extent possible, moderate to heavy rain

should also be avoided.

If heavy rain is encountered:

Thrust Levers

Adjust Slowly

If thrust changes are necessary, move the thrust levers slowly. Avoid

changing thrust lever direction until engines have stabilized at a

selected setting.

Turbulence

During flight in light to moderate turbulence, the autopilot and/or autothrottle may

remain engaged unless performance is objectionable. Increased thrust lever

activity can be expected when encountering wind, temperature changes and large

pressure changes. Short-time airspeed excursions of 10 to 15 knots can be

expected.

anticipated turbulence. Instruct flight attendants to check that all

passengers' seat belts are fastened.

AIRSPEED

CLIMB

280 knots or .76 Mach

CRUISE

Use FMC recommended thrust settings. If the

FMC is inoperative, refer to the Unreliable

Airspeed page in the Performance-Inflight

section for approximate N1 settings that

maintain near optimum penetration airspeed.

DESCENT

.76 Mach/280/250 knots. If severe turbulence is

encountered at altitudes below 15,000 feet and

the airplane gross weight is less than the

maximum landing weight, the airplane may be

slowed to 250 knots in the clean configuration.

Note: If an approach must be made into an area of severe turbulence,

delay flap extension as long as possible. The airplane can

withstand higher gust loads in the clean configuration.

SP.16.14

Boeing 737 Operations Manual

Windshear

Windshear is a change of wind speed and/or direction over a short distance along

the flight path. Severe windshear is that which produces airspeed changes greater

than 15 knots or vertical speed changes greater than 500 feet per minute.

Avoidance

The flight crew should search for any clues to the presence of windshear along the

intended flight path. Stay clear of thunderstorm cells and heavy precipitation and

areas of known windshear. If severe windshear is indicated, delay takeoff or do not

continue an approach.

The presence of windshear may be indicated by:

• Thunderstorm activity

• Virga (rain that evaporates before reaching the ground)

• PIREPS

• Low level windshear alerting system (LLWAS) warnings

Precaution

If windshear is suspected, be especially alert to any of the danger signals and be

prepared for the possibility of an inadvertent encounter. The following

precautionary actions are recommended if windshear is suspected:

Takeoff

•

Use maximum takeoff thrust instead of reduced thrust.

•

Use the longest suitable runway.

•

Be alert for any airspeed fluctuations during takeoff and initial

climb. Such fluctuations may be the first indication of windshear.

•

Know the all-engine initial climb pitch attitude. Rotate at the

normal rate to this attitude for all non-engine failure takeoffs.

Minimize reductions from the initial climb pitch attitude until

terrain and obstruction clearance is assured, unless stick shaker

activates.

•

Crew coordination and awareness are very important. Develop an

awareness of normal values of airspeed, attitude, vertical speed,

and airspeed build-up. Closely monitor vertical flight path

instruments such as vertical speed and altimeters. The pilot not

flying should be especially aware of vertical flight path

instruments and call out any deviations from normal.

•

Should airspeed fall below the trim airspeed, unusual control

column forces may be required to maintain the desired pitch

attitude. Stick shaker must be respected at all times.

SP.16.15

Supplementary Procedures -

Adverse Weather

Boeing 737 Operations Manual

• If windshear should be encountered near VR, and airspeed

suddenly decreases, there may not be sufficient runway left to

accelerate back to the normal VR. If there is insufficient runway

left to stop, initiate a normal rotation at least 2000 feet before the

end of the runway even if airspeed is low. Higher than normal

attitudes may be required to lift-off in the remaining runway.

Approach and Landing

• Select the minimum landing flap position consistent with field

length.

• Add an appropriate airspeed correction (correction applied in the

same manner as gust), the maximum command speed should not

exceed the lower of Vref + 20 knots or landing flap placard speed

minus 5 knots.

• Avoid large thrust reductions or trim changes in response to sudden

airspeed increases as these may be followed by airspeed decreases.

• Crosscheck flight director commands using vertical flight path

instruments.

• Crew coordination and awareness are very important, particularly

at night or in marginal weather conditions. Closely monitor the

vertical flight path instruments such as vertical speed, altimeters,

and glideslope displacement. The pilot not flying should call out

any deviations from normal. Use of the autopilot and autothrottle

for the approach may provide more monitoring and recognition

time.

Recovery

Accomplish the Windshear Escape Maneuver found in Non-Normal Maneuvers

section of this manual.
