FMA

Question 0

AT

IDLE

Answer 0

AT is reducing or has reduced thrust to flight Idle. It may engage in a VNAV descent. It will engage after FLARE is engaged.

Question 1

AT

SPD

Answer 1

Autothrottle controlling thrust to maintain speed selected in IAS/Mach, or if VNAV engaged, the speed as programmed by the FMC.

Question 2

AT

THR HOLD

Answer 2

Thrust levers remain in existing position or where manually placed

Question 3

AT

EPR

Answer 3

Autothrottle controlling to the selected EPR ref thrust

Question 4

AT

FLCH

Answer 4

Autothrottle controlling to a maximum of the selected mode reference thrust during climb and to a minimum thrust during descent

Question 5

AT

GA

Answer 5

Autothrottle controlling to a maximum reference thrust to maintain a climb rate of 2000’ per min

Question 6

PITCH

TO

Answer 6

On ground TO annunciation by selecting either FD switch on when both switches are off. The flight director pitch bar an initial pitch of approx 8 degrees up.

Question 7

PITCH

GA

Answer 7

AFDS system commands pitch to maintain existing speed or selected speed whichever is the greater.

Question 8

PITCH

VNAV SPD

Answer 8

VNAV provides pitch commands to maintain the FMC computed airspeed / path

VNAV SPD - the AFDS maintains the FMC speed displayed on the CDU climb or descent pages. The speed can be manually set by speed intervention.

Question 9

PITCH

VNAV PTH

Answer 9

The AFDS maintains FMC altitude or descent path with pitch commands. If the MCP altitude window is set to current cruise altitude, as the a/c approaches the TOD the CDU scratchpad message RESET MCP ALT displays.

Question 14

PITCH

FLARE

Answer 14

Flare (armed) during AUTOLAND displays below 1500ft RAD ALT.

Flare (active) during AUTOLAND flare activates at 50’ rad and deactivates at touchdown

Question 15

PITCH

ALT CAP

Answer 15

Transient manoeuvre entered automatically from

V/S FLCH VNAV CLB or descent to selected MCP altitude.

Question 16

ROLL

ATT

Answer 16

ATT -active. When the AP is first engaged or the flight director is first turned on in flight AFDS holds a bank angle between 5 and 30 degrees and will not roll to wings level.

When the bank angle is less than 5 degrees. AFDS returns to wins level HDG HOLD

When the bank angle is greater than 30 degrees. AFDS returns to 30 degrees of bank.

Question 17

PITCH

ALT HOLD

Answer 17

Activated by pushing the MCP ALT HOLD switch or capturing the selected altitude from V/S FLCH climb or descent.

Question 18

What are the 5 switch selections on MCP which will engage the AT.?

Answer 18

SPD EPR FLCH VNAV GA

Question 19

Pushing the EPR switch does what? 4 things

Answer 19

Selects AT EPR MODE
EPR annunciates on each FMA
Autothrottle holds ref thrust value displayed on EICAS subject to maximum speed limits
Updates FMC position to takeoff runway threshold position when selected for takeoff

Question 20

SELECTABLE ROLL MODES ON MCP

Answer 20

LNAV
HDG SEL
HDG HOLD

Question 21

Heading Bank Angle limits

Answer 21

High Speed 15 degrees

Low Speed 25 degrees

Question 22

When is NOT ON INTERCEPT HEADING displayed on ADI ?

Answer 22

If AC is not heading towards an active leg and more than 2.5 miles away

Question 23

SELECTABLE PITCH MODES ON ADI ?

Answer 23

ALT HOLD
VNAV
VS

Question 24

Is there automatic Speed Protection in VS ?

Answer 24

No

Question 25

During a FLCH climb what does the AT command and what does the AFDS Pitch channel command ?

Answer 25

AT commands THRUST AFDS commands SPEED Hence ADI displays FLCH SPD The AFDS alters pitch to maintain current speed. The AT applies thrust up to a max ref thrust in climb- full ref thrust for a large climb and less thrust for a small climb

Question 26

What happens at level off following a FLCH climb?

Answer 26

FMAs indicate : SPD ALT CAP then ALT HOLD

Question 27

What will be the INITIAL. AT and AFDS mode indications during a FLCH descent ?

Answer 27

FLCH | SPD

Question 28

During a protracted FLCH descent what will be the AT and AFDS FMAs ?

Answer 28

THR HLD | SPD - AFDS pitching to maintain the speed.(you can move the Thrust lever to alter rate of descent)

Question 29

What are the FMAs for a VNAV climb ?

Answer 29

EPR VNAV SPD eg when VNAV first selected at Acceleration Altitude. IAS window blanks and the FMS positions the speed bug. It also positions the Magenta bug (Ref EPR ). The FMS positions both speed and EPR bug (emphasise) AFDS uses pitch to maintain speed AT applies thrust to maintain EPR

Question 30

In a VNAV climb what happens to the FMAs if an intermediate ( not cruise level) altitude is captured?

Answer 30

SPD | ALT CAP then ALT HOLD

Question 31

When will you get DRAG REQUIRED ?

Answer 31

In a VNAV descent with a stronger than forecast tailwind IDLE VNAV PTH PATH will initially be maintained at the expense of speed . When it's more than 15 kts increase DRAG REQUIRED will be displayed

Question 32

What will happen in VNAV descent in PATH if speed is not kept under control ?

Answer 32

The path will be lost and IDLE VNAV SPD will display

Question 33

In a VNAV descent if stronger than expected headwind ?

Answer 33

Initially path will be maintained and speed will reduce below bug IDLE VNAV PTH more than 15 kts slow SPD VNAV PTH Here AT recovering the speed Then IDLE VNAV PTH will resume

Question 34

What happens when DES NOW is pressed?

Answer 34

This is only time EPR VNAV SPD is shown in the descent. This shows at the initial stages of descent until 1000ft per min is attained 1 EPR VNAV SPD 2 THR HOLD VNAV SPD 3 IDLE VNAV PTH

Question 35

Thinking about the MCP which 2 modes are AT ONLY ?

Answer 35

EPR | SPD

Question 36

Answer 36

GA (not on MCP) VNAV FLCH

Question 37

With LNAV engaged what provides the steering signals ?

Answer 37

FMS

Question 38

If VS is selected during a VNAV or FLCH climb what does AT mode change to ?

Answer 38

SPD | VS will be the pitch mode

Question 39

FLCH climb What do the A/T and AP do?

Answer 39

FLCH SPD AT applies thrust to up to REF thrust AFDS pitches to maintain speed at time of engagement (window)

Question 40

Is a FLCH climb or descent stopped when approaching..... MCP selected altitude FMS cruise altitude FMS constraint altitude ?

Answer 40

YES NO NO FLCH mode will ignore any FMS programmed profiles

Question 41

What does it mean if the Amber AUTO PILOT light and message are displayed with an amber line through the mode annunciation ?

Answer 41

Failure affecting the active mode only AP will stay connected in an attitude stabilising mode

Question 42

Which TWO conditions arm GO-around ?

Answer 42

Flaps out of up | GS capture

Question 43

What is the lowest point at which GA can be engaged?

Answer 43

2 secs after 5' radio

Question 44

When a Go-around is initiated what do the three FMA modes achieve?

Answer 44

AT GA thrust to 2000' per min AFDS pitch maintains current speed or MCP speed ROLL mode maintains RWY track

Question 45

What is the TMSP?

Answer 45

THRUST MODE SELECTOR PANEL - sets selected thrust mode reference TO. GA. CLB CRZ CON - selection of fixed and assumed temperature derated reference thrust values
