Question 1
The modern FMS was introduced on the?
A. Boeing 764
B. Boeing 765
C. Boeing 767
D. Boeing 768
View Answer
Ans : C
Explanation: The modern FMS was introduced on the Boeing 767, though earlier navigation computers did exist.
Question 2
The FMS sends the flight plan for display to the?
A. EFIS
B. ND
C. MFD
D. All of the above
View Answer
Ans : D
Explanation: The FMS sends the flight plan for display to the Electronic Flight Instrument System (EFIS), Navigation Display (ND), or Multifunction Display (MFD)
Question 3
Airline-quality GPS receivers act as the primary sensor as they have the highest accuracy and integrity.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: True, Airline-quality GPS receivers act as the primary sensor as they have the highest accuracy and integrity.
Question 4
The FMS mode is normally called?
A. VNAV
B. LNAV
C. Both A and B
D. None of the above
View Answer
Ans : C
Explanation: The FMS mode is normally called LNAV or Lateral Navigation for the lateral flight plan and VNAV or vertical navigation for the vertical flight plan. VNAV provides speed and pitch or altitude targets and LNAV provides roll steering command to the autopilot.
Question 5
Which one of the following is not a function of the FMS?
A. Flight guidance and control of flight path
B. Automatically switch between different types of communication
C. Monitor and regulate speed of the aircraft
D. Automatic control of engine thrust
View Answer
Ans : B
Explanation: The tasks of the FMS include Flight guidance and lateral and vertical control of the aircraft flight path, Monitoring the aircraft flight envelope and computing the optimum speed for each phase of the flight and ensuring safe margins are maintained with respect to the minimum and maximum speeds over the flight envelope, Automatic control of the engine thrust to control the aircraft speed. However, the communication systems are taken care manually by the pilot.
Question 6
The number of independent FMS in a typical commercial aircraft is?
A. 1
B. 2
C. 3
D. 4
View Answer
Ans : B
Explanation: There are two independent FMS in a typical commercial aircraft’s cockpit. FMS-1 is on the Captain’s side and FMS-2 on the First Officer’s side to carry ou the flight management functions. The reason why both are independent is that when one fails the other can take over.
Question 7
Both FMS 1 & 2 get information from only one FMC in the case of ______
A. Independent mode
B. Loss of one FMC
C. Double mode
D. Single mode
View Answer
Ans : D
Explanation: In Single mode operating mode of the FMS two of the FMC is not in operation and this might cause one of the two FMS to fail. Hence both the FMS get information from one FMC.
Question 8
What filter is used by the FMS to estimate the position of the aircraft from various sensors?
A. Position error filter
B. GPS filter
C. Gyro and accelerometer filter
D. Kalman filter
View Answer
Ans : D
Explanation: The FMS combines the data from the navigational sources, comprising the inertial systems, GPS and the radio navigation systems, in a Kalman filter to derive the best estimate of the aircraft position. Each navigation system has its own advantages and limits, a Kalman filter combines the resource from all the systems to provide a more accurate position of the aircraft.
Question 9
All FMSs contain a navigation database
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: True, All FMSs contain a navigation database
Question 10
In how many days, navigation database normally updated?
A. 20 days
B. 25 days
C. 28 days
D. 30 days
View Answer
Ans : C
Explanation: The navigation database (NDB) is normally updated every 28 days, in order to ensure that its contents are current
