1.-The horizontal mode of AFCS mantain:
Heading, VOR radial/ILS locator and LNAV route and roll angle
Heading, altitude and vertical speed
Vertical speed, IAS/Mach
Turbulence penetration, vertical speed and IAS/Mach
2.-How simplex AFCS system Works?
Some components could be redundant, but a single failure renders the system inoperative
A single failure does not render the system inoperative
It has multiplex simplex systems to avoid failure
AFCS does not have simplex system, i aviation are always multiplex, triplex and quadruplex
3.- How yaw dumper Works?
It is a system which moves the ailerons to avoid the dutch roll
It prevents the dutch roll by using the rudder
It prevents the tuck under by using the rudder
It only moves the ailerons to prevent the tuck under and it is only used in small aircraft
4.-The mach trim system:
Is a system attached to the pitch cannel
It does not depend of the AFCS
Prevents the tuck under
All of above
6.-The rate trigger system of a AFCS:
automatically disconnects the autopilot if the rate exceeds a set threshold
It is more used for stability tan for control
Compare the different outputs from sensors
None of above
7.-The combined pitch/roll system of AFCS:
Holds altitude, vertical speed, IAS/Mach and Attitude
Heading, VOR radial/ILS locator and LNAV route
Control TOGA, Control Wheel steering, touch Wheel steering and turbulence penetration
8.-The speed of response in duplex system of AFCS:
Can be improved by using comparator
Depends only on the singular response of any sensors
Both are correct
Both are false
1.How does a Primary radar work?
It transmits a specific low energy signal (the interrogation) to a known target
High energy is directed via an antenna to illuminate a ‘target’
Using medium energy beams to detect the ‘target’
It works with infrared waves to send the signals
2. How does a Secondary Surveillance Radar work?
It transmits a specific low energy signal (the interrogation) to a known target.
High energy is directed via an antenna to illuminate a ‘target’.
Using medium energy beams to detect the ‘target’.
It works with infrared waves to send the signals.
3. Which is a problem of Primary Radars?
It only provides range measurement.
It only provides azimuth measurement
Small ratio reflected/emitted energy.
It can not detect objects in movement.
4. Interrogator and reply signals are concept of:
Primary Radar.
Secondary Surveillance Radar
Both of them.
None of them.
5. Which is the main difference between the Mode A and the Mode C Transponder modes?
A) Mode A only shows the 4 digit code whereas the Mode C shows also the altitude.
B) Mode A only shows the 4 digit code whereas the Mode C shows also the velocity.
C) A) and B) are true.
D) Mode A is like Mode S.
6. Which is the main difference of Mode S against Mode A and C.
It is cheaper than the others.
It is completely automatic.
It allows a specific aircraft to be interrogated.
Is only for military use.
7. What is the concept of ADS-B?
The aircraft gets it position from the GNSS constellation and then it broadcasts it to other aircrafts/ground stations.
It stands for Advisory Data Source-Binary and it controls the defective data and advises the air-crew.
It is a non-reactive radar used mainly in civil aviation.
8. What is the meaning of Data Link?
A) The action to link data with cables through the plane.
B) To create links between devices that share the same data.
C) D) and A).
D) Connection between locations to transmit and receive digital info.
1. What is the Flight Management System?
Is an integrated automatic system.
Provides optimum economy of flight.
Reduces flight deck workload.
All the above are correct.
2. What is the EFIS?
Is the FMS in electronic version.
Is the CADC in electronic version.
Is the ADI and HSI in electronic version.
Is the ADI, HSI and ASI in electronic version.
3. How many displays are typically in a FMS – Crew Interface?
1
2
3
4
4. What are characteristics of the CDU?
Small screen with numeric information
Big screen with alpha-numeric information.
Small screen with alpha-numeric information.
Big screen with numeric information.
5. Which of the following is not a FMS function?
Air Data.
Fuel State.
Navigation Database.
Stall Speed.
6. In the aircraft performance model, what are the dimensions computed?
X,y,z.
X, y, z, time.
X, x’, y, y’, z, z’.
X, y, z, speed.
7. What is LNAV?
The ability to navigate laterally in two dimensions plus the ability to navigate in the vertical plane.
The ability to navigate laterally in two dimension.
The ability to navigate in three-dimensions plus the addition of time constraints for the satisfaction of time of arrival at a waypoint.
The capability of four-dimensional navigation together with the addition of an aircraft specific performance model.
8. What is VNAV?
The ability to navigate in three-dimensions plus the addition of time constraints for the satisfaction of time of arrival at a waypoint
