In Flight Operation

Question 1

Fan ice Removal Engine vibration

Answer 1

do the following on both engines, one engine at a time:
ENGINE START switch ……………………….. FLT
Thrust ……………………………………………….Adjust
Adjust thrust to 45% N1. After five seconds, increase thrust lever slowly to a minimum of 80% N1.
thrust increase must continue to a minimum of 80% N1 to remove ice from the fan blades even if vibration stopped

Question 2

Engines Run Up

When engine anti-ice is required and the OAT is 3°C or below, do an engine run up as follows:

Answer 2

Run-up to a minimum of 70% N1 for approximately 30
seconds duration at intervals no greater than 30 minutes.
When operating in conditions of freezing rain, freezing
drizzle, freezing fog or heavy snow, run-ups to a minimum
of 70% N1 for approximately 1 second duration at intervals
no greater than 10 minutes enhance ice shedding.
או בקיצור
70%/30sec/30 min normal
70%/1sec/10 min freezing/ heavy snow

Question 3

If Run Up cannot be made due airport conditions:

Answer 3

then set a thrust level as high as practical and time at that thrust level.

Question 4

Nuisance Stall Warning Stick Shaker Events bulletin

when maneuvering during flap retraction from Flaps 1 to Flaps Up with antiice selected ON.

Answer 4

limit bank angle to 15 degrees until the Leading Edge Flaps
Transit light has extinguished. If a higher bank angle is required during this time, avoid the selection of Flaps 1 to Flaps Up until maneuvering is complete or bank angles are 15 degrees or less.
Note: A non-maneuvering segment of 1 nm with 2E or 2.5 nm with 1E will allow for flaps to be retracted from Flaps 1 to Flaps Up.

Question 5

Nuisance Stall Warning Stick Shaker Events bulletin
when Maneuvering at V2 speed following an engine failure on takeoff when Wing Anti-Ice has been selected ON after liftoff.

Answer 5

Do not turn Wing Anti-Ice ON until airspeed has increased to at least V2+15 knots.

Question 6

Fan Ice Removal

Answer 6

If flight in moderate to severe icing conditions cannot be

avoided, do the following on both engines, one engine at a time at 15 minute intervals:80% N1 for 1 second

Question 7

Moderate to Heavy Rain, Hail or Sleet

If encountered or anticipated:

Answer 7

ENGINE START switches ………………………………………….. CONT
Autothrottle …………………………………………………………. Disengage
Thrust Levers ………………………………………………….Adjust Slowly
If thrust changes necessary, move levers slowly.
Avoid changing thrust lever direction until engines stabilized
IAS/MACH …………………………………………….. Use a slower speed
Using a slower speed improves engine tolerance to heavy
precipitation intake.
Consider starting the APU (if available)

Question 8

Severe Turbulence

Answer 8

Passenger signs ………………………………………………..ON
YawDamper ………………………………………………………ON
Autothrottle ………………………………………………………Disengage
AUTOPILOT ……………………………………………………….CWS
Note: If sustained trimming occurs, disengage the autopilot.
ENGINE START switches ………………………………………………………. FLT
Thrust …………………………………………………………………………………….. Set
Set thrust as needed for the phase of flight. Change thrust setting
only if needed to modify an unacceptable speed trend.
Use FMC recommended thrust settings.

Question 9

Windshear

Answer 9

1.Takeoff with full rated takeoff thrust is recommended

Question 10

VMC

Answer 10

1. Flight visibility 8 km above 10,000 ft AMSL and 5 km below
   10,000 ft AMSL;
2. Distance from cloud 1,500 m horizontally and 1,000 ft vertically; and
3. Ceiling is not below 1,500 ft

Question 11

LRC

Answer 11

1. The speed above MRC that result it 1% decrease in fuel mileage traded for 5% in higher velocity.
2. The FMC does not apply wind corrections to LRC.
3. Provides the best buffet margin at all cruise altitudes.
4. 737=0.79M/ cost index 30

Question 12

Low fuel temp

3° C above the fuel freeze point or - 43° C whichever is higher

Answer 12

1. Do QRH-In extreme conditions, it may be necessary to descend as low as FL250.
2. OMA- FCTM procedure-do so if the temperature is forecast to be below -66 °C SAT for a period of 2 hours any time after the first 4 hours of the flight.
3. • climb or descend to a warmer air mass
   • deviate to a warmer air mass
   • increase Mach number.

Question 13

Takeoff with CSFF on lower wing surfaces is allowable

Answer 13

provided all
of the following condition are met::
• Ambient air temperature is at or above +4°C,
• There is no precipitation or visible moisture (rain, snow, drizzle,
or fog with less than 1 mile visibility)
• Tank fuel temperature is at or above -16°C,
• All leading edge devices, all control surfaces, tab surfaces,
winglet surfaces, and control surface balance panel cavities
must be free of snow, ice and frost.
If all of the above conditions are not met, takeoff with light coatings
of frost, up to 1/8 inch (3 mm) in thickness, on lower wing surfaces
due to cold fuel is allowable;

Question 14

Takeoff with CSFF on upper wing surfaces is allowed

Answer 14

provided all of the following conditions are met:
• The CSFF on the wing tank upper surfaces is only within the
lines defining the permissible CSFF area with no ice or frost on
the leading edges or control surfaces
• Ambient air temperature is at or above +4°C.
• There is no precipitation or visible moisture (rain, snow, drizzle,
or fog with less than 1 mile visibility)
• Tank fuel temperature is at or above -16°C.
If all of the above conditions are not met, all snow, ice and frost on the
wings must be removed using appropriate deicing/anti-icing
procedures.

Question 15

Answer 15

Initial segment : begin at IAF Ends IF obstacle clearance 1000’
Intermediate seg. : begin at IF Ends FAF clearance 500’
