FCOM 1

Question 1

Final loadsheet figures showing ‘Compliance with’ the provisional loadsheet indicate that the actual TOW is within +???? kg and -???? kg of the provisional TOW and the MACTOW and MACZFW are within ±??% of the provisional figure.

Answer 1

+1,000kg & -4,000kg
within ±2%
Final loadsheet figures showing ‘Revisions to’ the provisional loadsheet indicate that the actual TOW, MACTOW and/or MACZFW are outside the tolerances given above. The affected values are indicated by //. Revisions require pilots to complete NP.21 Critical Data Procedure – P1 and P2.
However, if the only change is to MACTOW, the pilot monitoring may amend CG TRIM on TAKEOFF REF 1/2, and then re-trim accordingly. NP.21 Before Takeoff Procedure details the sequence of events.
Note: For CG TRIM changes in excess of 3%, the FMC may delete other TAKEOFF REF data, which would then require a Critical Data Procedure.

Question 2

When both of the following exist, do an engine run-up to minimize ice build-up:

Answer 2

1) OAT is -7°C or below
2) visible moisture (clouds, fog with visibility of one statute mile [1600 m] or less, rain, snow, sleet, ice crystals, and so on)

Do the following procedure:
Check that the area behind the airplane is clear.
P1
Run-up to a minimum of 20 TPR (42% N1) for at least 30 seconds at intervals no greater than 60 minutes.

Question 3

The APU battery is designed to support ?? consecutive start attempts.

Answer 3

Two

If the APU fails to start after the second attempt, a 5 minute cooling period must be observed before a third attempt is made.

Question 4

Do the normal Takeoff Procedure with the following modification:

When engine anti-ice is required and the OAT is ??? or below, the takeoff must be preceded by a static engine run-up. Use the following procedure:

Answer 4

3°C

Run-up to a minimum of 50% N1 and a maximum of 55% N1 for at least 2 seconds to shed any possible ice on the fan.

Question 5

What flap settings can you use speedbrake with?

Answer 5

All flap settings

I have spoken with my counterpart in Virgin about their policy. They have latched onto the statement in the FCTM that there is buffet at F20, and they dislike seeing SPEEDBRAKE EXTENDED cautions with landing flap. They also tend to stick to standard Normal Procedures flap extension 1, 5, 20, Land (25,30), and don’t make much use of the intermediate settings that the FCTM permits you to use should you wish. That’s a matter for their own company policies. Neither their policy nor ours is “wrong”.

However, to be clear. You are permitted to use Speedbrake with any flap setting on approach, including below 1000ft in BA on the 787 or 777 (you will see that the stable approach policy makes no mention of speedbrake - deliberately so. Some fleets have an aircraft limitation in the FCOM, but not ours).

LHR is very noise sensitive, as we know, and lowering the gear early makes much more noise than using the speedbrake. In general, therefore, we would encourage you to work hard to be “in the groove” and lower the gear at the standard point, making use of the flexibility that permitted intermediate flap settings and speedbrake affords you. Force Majeure applies though, so you may also drop the gear early if you really have to. Mitch Preston.

Question 6

Adverse Weather. Contaminated Runway: SP.16

Takeoffs are not recommended when:

Answer 6

Slush or standing water depth more than 0.5 inches (13 mm)

Wet snow depth is more than 1.2 inches (30 mm)

Dry snow depth is more than 3.9 inches (100 mm).

Question 7

Adverse Wx SP.16
If the fuel temperature is less than or equal to ??? degrees C, and if the electric hydraulic pump selectors are in the AUTO or OFF position for more than ?? minutes prior to engine hydraulic pump operation:

Answer 7

-17
10 mins
Notify maintenance personnel.

During the hydraulic panel preflight, if all electric pump selectors are found selected ON and the APU is running, maintenance personnel may have performed a maintenance procedure for cold weather hydraulic system warm-up. If maintenance personnel have performed the cold weather hydraulic system warm-up procedure, leave the electric pump selectors ON and the APU running. This ensures all four hydraulic electric pumps remain operating and the hydraulic fluid remains warmed. During the Before Start Procedure, select all electric pumps AUTO and resume normal procedures for operation of the hydraulic systems.
