Flight Management And Navigation Flashcards
If LNAV is armed prior to takeoff, it will engage at
— feet RA and —.
. [8.110.10]
50, within 2.5 NM of the active route leg
After takeoff during acceleration, VNAV commands a speed___ knots below the existing flaps placard speed, based on flap handle position. [8.110.10]
5
Using the CLB DIR (Climb Direct) function deletes all waypoint altitude constraints between the airplane altitude and: [8.110.20]
The lower of the FMC cruise altitude or the MCP altitude.
In flight, with an interruption of power or inadvertent shutdown of the IRSs, when power is restored: [8.110.30]
The IRSs can be fully restored within approximately 10 minutes if GPS data is available.
The ISFD receives Pitot & Static data from: [8.100.10]
The Center Pitot / Static System.
Which of the following may be used by the FMC for position updating? [8.110.10]
- GPS/IRU.
- DME/DME IRS.
Which statement is true, when operating with a triple FMC failure? [8.110.10]
A. New waypoints must be entered using lat / long and are entered on the ALTN NAV page of the TCP.
B. ILS/GLS Radio tuning is available through the ALTN NAV Radio page of the TCP.
C. PFD mini-map and ND map displays are inoperative.
D. All the above.
The EICAS shows “FMC”. Which of the following could cause this message to display? [8.110.10]
All three FMCs have failed.
Manual FMC position updates: [8.110.10]
May be accomplished using any of the positions shown on POS REF 2/4.
With regard to VNAV descents which of the following is true? [8.110.10]
A. Selecting DES NOW prompt on the VNAV DES page will start a descent to capture the VNAV PTH.
B. Using the MCP altitude selector to initiate a descent when within 50 NM of the computed top of descent initiates a DES NOW function.
C. Using the MCP altitude selector to initiate a descent when greater than 50 NM of the computed top of descent changes the FMC cruise altitude and initiate a cruise descent.
D. All the above.
The FMC transitions to approach if a published approach has been selected and incorporated into the active flight plan and which of the following have occurred? [8.110.10]
A. The airplane has sequenced the first waypoint of the active approach.
B. The missed approach point is the active waypoint and the distance to go is less than 25 NM.
C. The descent phase is active and the flaps are out of UP.
D. All the above
The IRSs can be fully realigned in flight using which of the following methods? [8.110.30]
Using GPS position information.
If all IRU inertial data fails which of the following occurs? [8.110.30]
- The FMC continues to receive hybrid GPS-inertial position solutions using the AHRU inertial sensors combined with GPS position.
- The EICAS advisory message NAV IRU is displayed.
A conditional waypoint is indicated when an event occurs, and is not a geographically- fixed position. [8.110.10]
True or False?
True.
ND map shift errors can be detected by comparing the position of the airplane on the ND map with data from which of the following: [8.110.10]
A. ILS.
B. DME.
C. VOR.
D. All the above.
The AHRU supplies: [8.110.30]
- Attitude.
- Heading.
