Answer 16

T/C to TOD

Question 17

When is descent phase?

Answer 17

TOD to start of approach phase

Question 18

Flight Complete Phase?

Answer 18

30 seconds free shutdown, flight complete phase clears the active flight plan and load data

Question 19

How close to route must aircraft be to sequence a waypoint?

Answer 19

Must be within 21 miles, unless on an offset route

Question 20

If GPS off, how do you position aircraft for takeoff?

Answer 20

Pressing TOGA will position aircraft to takeoff runway threshold , or position shift position, if entered

Question 21

What is the polar region as defined by the 787 database?

Answer 21

82N and up, except for that region defined by 80W to 170W and north of 73N

Question 22

What are the flight deck indications that the aircraft is referenced to true north?

Answer 22

White box around TRU at top of both PFD and ND

CDU legs page will display a “T” next to the leg course data

Question 23

If heading reference is TRU in the descent phase, what indication will you see?

Answer 23

An amber box around TRU on both PFD and ND

Question 24

When would you select TRUE with the HEADING REF switch?

Answer 24

When operating the autopilot in the polar region in other than LNAV

Question 25

NAV INERTIAL SYS?

Answer 25

IRS failed in polar region All autopilot and AFDS modes fail Entry of a reference heading on the POS INIT page restores HDG HOLD and HDG SEL Heading must be renewed every 10 mins GLS continues to supply navigation data and active route information still available

Question 26

IRU position graphic? GPS?

Answer 26

Asterisk on ND TIE fighter

Question 27

What is the supposition of ANP?

Answer 27

Airplane position estimated to be within ANP circle 95% of the time

Question 28

SINGLE FMC?

Answer 28

Two FMCS have failed in flight Third FMC has taken over All data retained, but LNAV and VNAV deselect The flight plan will have to be deactivated and LNAV and VNAV deselected

Question 29

What are the indications if all FMCS fail?

Answer 29

FMC loss of PFD mini map Loss of ND maps Loss of CDU pages on MFD Loss of both LNAV and VNAV

Question 30

When armed for takeoff, when does LNAV engage?

Answer 30

At 50 feet, when laterally within 2.5nm of the active route leg

Question 31

LNAV BANK ANGLE LIM?

Answer 31

The FMC looks 5 mins ahead and gauges the LNAV course change. It may limit the bank angle to preclude a loss of airspeed or altitude. This message will be displayed

Question 32

FMC HOLD AIRSPACE

Answer 32

FMC evaluates the need for a bank limit 3 min from a hold If it determines the hold will be outside of the protected airspace, this is the EICAS that will be displayed

Question 33

If armed for takeoff, when does VNAV engage?

Answer 33

At 400 feet above field elevation

Question 34

VNAV STEP CLIMB

Answer 34

Climb is not initiated within 5 minutes after passing a step climb point

Question 35

Pressing the speed selector?

Answer 35

Same actions as speed intervene

Question 36

Pressing the altitude selector?

Answer 36

Same actions as altitude intervene

Question 37

Where is the end of descent point calculated (for all but VOR approaches)?

Answer 37

50 feet above the runway threshold

Question 38

What is the end of descent point for VOR approaches?

Answer 38

The missed approach point

Question 39

THRUST REQUIRED in the CDU help window?

Question 41

With VNAV, what is the importance of the 50nm point before TOD?

Answer 41

If you press the altitude selector before this point (with a lower-than-cruise altitude selected), the FMC will re-cruise to the selected altitude. Within 50nm, the aircraft will start a shallow descent and capture the descent path

Question 42

FMC transitions to the approach phase when:

Answer 42

Descent mode is active and flaps are down Airplane has sequences the first waypoint of the approach The airplane is on a direct to intercept course-to the active waypoint and the distance is less than 12 nm The MAP is the active waypoint and the distance to go is less than 25 nm
