General facts and figures

Question 1

VNAV Take off.

Which modes go through the FMA

Answer 1

TO/GA pushed:
N1              -           -   TO/GA
84kts
THR HLD   -         -    TO/GA
50'RA
THR HLD  - LNAV  - TO/GA
400'RA
THR HLD  -  LNAV - VNAV SPD
800'
ARM          -  LNAV  -VNAV SPD
CMD

Question 2

FMC climb mode
ATC expedite climb command,
what action required

Answer 2

Set max rate on CLB page

or max angle for obstacle/waypoint altitude constraints

Question 3

When is VNAV PTH shown?

Answer 3

AFDS maintains FMC altitude or descent path with pitch commands.
speed controlled by pilot/ATT

Question 4

When is VNAV SPD shown?

Answer 4

AFDS maintains the TGT SPD shown on the ASI in speed intervention or on the CDU CLB/DES page.
Speed commanded by pitch

Question 5

When is VNAV ALT shown?

Answer 5

Always shown when a conflict occurs between VNAV profile and the MCP ALT and airplane levels at the MCP ALT.

Question 6

50NM => T/D ALT INT

Answer 6

descent initiated with consequent level off before second T/D
CRZ DES mode on DES page.
MCP ALT will become the new CRZ ALT.
New T/D is calculated

Question 7

50NM

Answer 7

DES page title will change from DES to ALT CRZ DES inside of 50NM to T/D.

Question 8

Late descent

Answer 8

1) If ATC doesn’t clear for descent,
2) open speed intervene reduce speed to conserve energy.
3) Once cleared, higher speed and or speed brakes required to recapture path.
OR;
start fast descent and
4) keep high speed by setting higher TGT speed in box. Path will be recalculated

Question 9

What actions must be taken if aircraft deviates from active PTH?

Answer 9

VNAV PTH will revert to VNAV SPD.
Monitor and call this.
take action to recapture the PTH

Question 10

Descent planning at or below

Answer 10

1) enter AT or BELOW constraints in the FMC LEGS page
2) connect the shortcutted WYP and DO NOT EXEC
3) Let FMC recompute lower altitude at a given point and memorize it
4) ERASE shortcut
5) enter altitude constriction at the point in existing route at XXXXB and execute.

Question 14

FMC CDY ENTRY PROCEDURE

Answer 14

–INIT REF enter AZFW and call out. captain compares to load sheet. (ATOW plus TF) and check with load sheet
EXECUTE
–N1 LIMIT assumed temp and derate. checks and checks gauges
–TAKEOFF PAGE - FLAPS, MACTOW captain verifies and enters V2 in MCP arm ATT LNAV VNAV
–APPROACH REF PAGE verify VREF40 cross check with OPT
