Systems - MCP / DSP / EFIS Control Panel

Question 1

If the EFIS control panel should fail, is there another way to make inputs?

Answer 1

Yes. Through the CDU menu page.

Question 2

If the display select panel should fail, is there another way to make inputs?

Answer 2

Yes. Through the CDU menu page

Question 3

What is the minimum altitude for autopilot engagement and usage?

Answer 3

• 200’ on takeoff
• 50’ below MDA on a non-precision approach
• without land 2 or 3 annunciated you must disconnect before 200’ AGL.

Question 4

What does the autopilot disengage bar do besides disengaging the autopilot?

Answer 4

Disables bank angle protection

Question 5

When is the CLB CON switch used?

Answer 5

• Inop on the ground and below 400’
• With 2 engines operating changes the thrust limit to the FMC selected climb thrust
• With 1 engine, changes the thrust limit to max continuous.

Question 6

If the approach mode is selected on an ILS approach and you are below 1500ft (Land 3 annunciated) can you de-select the approach mode by pushing the switch?

Answer 6

No. You must disconnect the autopilot, turnoff both flight directors, then back on. Then select the desired flight director function and re-engage the autopilot.

Question 7

What is the max rate climb?

Answer 7

Flaps up Maneuver speed + 60kts until intercepting .82M

Question 8

What would you consider if you saw LANDING ALT in the advisory EICAS message?

Answer 8

There is no landing altitude available from the FMC. Check the destination

Question 9

What is the function of the autopilot disengage bar?

Answer 9

• disengages both A/Ps
• disables master warning lights
• disables aural warnings
• disables bank angle protection

Question 10

When armed:
when does LNAV become active?
when does VNAV become active?

Answer 10

LNAV - 50 feet RA
VNAV - 400 feet RA

Question 11

When VNAV is engaged, what program does it follow?

Answer 11

speed selections appearing on the VNAV CLB, CRZ and DES pages according to COST INDEX

Question 12

When FLCH is selected in auto flight what happens?

Answer 12

A/T reengages, aircraft will climb or descend to ALT set, existing airspeed appears in SPD window

Question 13

When VERTICAL SPEED is selected in auto flight, will current airspeed be maintained?

Answer 13

V/S regulates to descent or climb rate not airspeed, more thrust or drag may be necessary to maintain speed

Question 14

What is the difference between the HDG and TRK functions?

Answer 14

TRK provides wind compensation, HDG does not, TRK SEL can be used if LNAV fails

Question 15

Explain the function of FPV (flight path vector)

Answer 15

level flight can be achieved in manual flight by placing the FPV symbol over the PFD horizon bar

Question 16

Explain the function of FPA (flight path angle)

Answer 16

a constant descent angle can be set for N-P approach, e.g. a typical glide slope angle is 3°

Question 17

In cruise with VNAV PTH on the FMA at FL350 and cleared to FL390. How would you climb?

Answer 17

set FL390 in MCP altitude window and push ALT knob

Question 18

What does the RADIO/BARO knob do?

Answer 18

selects minimums to radio or barometric value on PFD

Question 19

What does pressing the BARO knob do?

Answer 19

sets STD

Question 20

Is there a similar button on the standby altimeter?

Answer 20

yes

Question 21

How do you deal with an inoperative EFIS control panel?

Answer 21

read ECL then perform same functions on CDU

Question 22

If the DSP should fail, is there another way to make inputs and what does DSP stand for?

Answer 22

Yes. Through the CDU menu page. (on all 3) Display Select Panel

Question 23

TFC switch?

Answer 23

Displays traffic. Transponder in TA/RA

Question 24

At what altitude does LNAV engage?

Answer 24

50 feet and 2.5 miles of course

Question 25

What altitude does VNAV engage?

Answer 25

400 feet

Question 26

AT what altitude can you discontinue a localizer approach mode by pushing the LOC a second time?

Answer 26

Above 1500 AGL

Question 27

What are some other ways to discontinue a localizer or ILS approach?

Answer 27

1. press TOGA
2. turn Autopilot/FD off
3. then turn Autopilot/FD on

Question 28

How does the captain go about using the Observer’s audio control panel?

Answer 28

Using the OBS AUDIO selector (right side of center selector panel)

Question 29

You have Flt planned the FMC to Climb to FL 220. You have armed VNAV for flight. On climb what is shown in the VMC window of the FMC?

Answer 29

VNAV Speed

Question 30

Before reaching FL220 you are cleared to FL 170 and told that will be your final. You place 170 in the MCP and push the altitude selector. Where will the plane level out?

Answer 30

FL170

Question 31

What will the FMA say?

Answer 31

VNAV ALT.
You will need to manually put 170 as a cruise in the FMC to GET VNAV PATH.

Question 32

Is it possible to see VNAV PATH in a climb?

Answer 32

No

Question 33

What does VNAV ALT mean?

Answer 33

Conflict between VNAV and MCP

Question 34

How do you know when the ILS has been identified?

Answer 34

Turns from Freq to Identifier
