Flight Controls

Question 1

What is the effect of pushing the Pitch Trim Switches

Push (both switches) –

Answer 1

in the normal mode in flight, changes the trim reference airspeed
in the normal mode on the ground, moves the stabilizer
in the secondary and direct modes, moves the stabilizer.

Question 2

The primary flight control system provides flight envelope protection when operating in normal mode. They are :-

Answer 2

stall protection
overspeed protection
bank angle protection.

Question 3

In the Secondary and Direct mode, the following functions are NOT available:

Answer 3

autopilot
auto speedbrakes
envelope protection
gust suppression
manual rudder trim cancel switch
thrust asymmetry compensation
yaw damping May be Inop 
G-STBA - G-STBL, G-YMMR - G-YMMU
tail strike protection

Question 4

Stall Protection. What does the Amber band represent?

Answer 4

Top of amber band is minimum manoeuvre speed. It’s the lowest speed you can trim to.
Bottom of the Amber band is the stall speed.

Question 5

The green band is calculated using the FMC inputs of CG, gross weight, and takeoff thrust.
In G-STBA - G-STBL, G-YMMR - G-YMMU it is also calculated using the FMC input of :-

Answer 5

V1

Question 6

After Pushback, when is the Flight Control Check commenced

Answer 6

once the Ground Crew have given the ‘all clear’ signal.

Question 7

Only change the flap in a non-normal G/A if

Answer 7

the QRH/ECL instructs you to. Eg
In the HYD ECL it doesn’t say move the flaps therefore you don’t, you stay at F20. Whereas in the engine failure ECL (for example) it says use F20 for approach and F5 for the G/A

Question 8

According to the Groundschool engineer, Alternate Flaps takes …. extra miles.

Answer 8

10

Question 9

In the Secondary Flap mode, 0-5 takes ……. mins and

5-20 takes …. min. Therefore initiate Flap 1 with …..no to go.

Answer 9

4 min
1 min
40 nm

5 mins at 210kts is just under 20nm, therefore initiate F1 with 40nm to go. Tell ATC you intentions.

Question 10

Can Alternate Gear be raised again?

Answer 10

No, therefore tell ATC your intention. Ask for an early Landing clearance with no other Landings or Departures on the Runway by the time you commence your Approach.

Question 11

How long does Alternate Gear take to extend?

Answer 11

Plan 2 mins/ 6nm before descent from your Platform Altitude if you are not performance limited.
If you are then wait until you are descending.

Question 12

If you do not have normal brakes, then all other braking systems require…..

Answer 12

Maually braking.

Question 13

When using Alternate Flaps, Brief that you are now in Control of……

Answer 13

your own Aysmmetry, so check for any unintended rolling

Question 14

Slats only move when positioned to

Answer 14

1 or 25/30.

Question 15

With Flaps/Slats Primary, the Flaps/Slats will move automatically in

Answer 15

the Secondary mode.

Question 16

With Flaps/Slats Control, you will need to move the Flaps/Slats in the

Answer 16

Alternate mode.

Question 17

With Flaps/Slats Drive, you will …..be able to move the Flaps/Slats from their current position. You are going nowhere if it happens on retraction.

Answer 17

not

Question 18

During what 3 Checklists will you require Alternate Flaps?

Answer 18

SLATS/FLAPS CONTROL

AIRSPEED UNRELIABLE

Question 19

Alternate Flap mode is limited to a maximum of Flap

Answer 19

20

In fact the checklist will always require a landing at F20

Question 20

Can you Autoland with the Flaps in Alternate mode.

Answer 20

Yes if it is only a Slats/Flaps Controls issue. Obviously not if part of the Airspeed Unreliable Checklist.

Question 21

Can you Autoland with a Flaps/Slaps Primary Fail issue

Answer 21

Yes.

Question 22

Can you Autoland with Slats/Flaps Drive?

Answer 22

No

Question 23

What does FLIGHT CONTROL MODE mean?

Answer 23

The flight control system is in the secondary mode.

Amongst other things, Autopilot will be inop and Envelope protection functions are inop

Question 24

The Flaps and Slats have their own

Answer 24

Independent system.

So a Slats Drive will not affect the Flaps

Question 25

Aileron trim is…….. when the Autopilot is engaged.

Answer 25

inhibited

Question 26

The rudder trim control can be used to command manual rudder trim in all three flight control modes. Two rudder trim speeds are available. Low rate rudder trim is commanded by rotating the control to the detent. High rate rudder trim is commanded by rotating the control……. the detent.
Manual Trim Cancel switch actuation causes manually set rudder trim to move to the zero units position at the high speed trim rate.
The zero position achieved by actuating the switch is not as accurate as manually trimming to zero units. The switch has no effect on rudder trim inputs from TAC.
