1. The acronym CNI means:
Centro Nacional de Inteligencia
Communication, Navigation and Identification
Communicate, Navigate and Intentions
Comunication and Identification
2. Types of system comunications
a) VHF
b) SATCOM
c) Online
d) a and b
3. Types of system comunications
Data links.
ATC
TACAN
All are false.
4. Types of system identification
TCAS
IFF
All are correct.
5. Choose the correct answer:
Civil do not usually use UHF comm.
IFF is not compatible with civil users.
Military may use UHF SATCOM.
6. Referring to HF communications:
It does not communicate beyond line of sight.
It has interferences.
Short range between air and ground.
It is a type of identification system.
7. SELCAL:
Selective calling: reduces the burden on the flight crew by alerting them to the need to respond the uncomming messages.
Is a system of VHF.
Similar to AM modulation.
Selective calling: increases the burden on the flight crew by alerting them to the need to respond the uncomming messages.
8. Data link:
Is an improvement over HF voice communications owing to the bit encoding inherent in a data link message format which permits the use of error -correcting codes.
Has a very low data rate.
Has a rapid network acquisition.
1. HFDL :
Is High Frequency DataLink that has stations that has wide coverage
It has fast date rate
It is complex
It is only possible one simultaneous band
2. At high frequencies in VHF:
a) The band does not adapt to the Earth
b) It travells in straight lines
c) a and b
d) It adapts perfectly to the Earth
3. The frequency of guard channel is:
UHF: 243.00 MHZ VHF: 121.5 MHZ
UHF: 116.6 MHZ VHF: 212.0 MHZ
UHF: 196.6 MHZ VHF: 211.0 MHZ
UHF: 117.6 MHZ VHF: 202.0 MHZ
4. VHF communications:
It has minimal interferences
It has high quality of sound
Military must maintain a listen watch on guard frequency
All of them are true
5. ACARS:
a) Is a datalink that emits information like passengers loads, fuel data and engine performance date
b) Is datalink in UHF that does not emit any info
c) Is one of the 3 pieces of VHF equipment and it is very used
d) A and c
6. SATCOM:
Uses 4 geostationary satellites
They cover with high intensity the poles
It means Satellite Coordination Moon
Uses 10 stationary satellite
7. Geo locations:
a) Are subdivided into fixed slots of 2 degrees longitudinal
b) Are subdivided into fixed slots of 10 degrees longitudinal
c) Is occuped by geostationary satellites whose change in position is the same as the Eart
1. The Flight Director System:
a) Computes the pitch and roll commands to achieve or maintain a condition of flight
b) The system applied the corrections needed
c) The commands are applied by the crew
d) A and C are true
2. According to the Flight Director Modes
a) The vertical mode includes the velocity and the navigation
b) The horizontal mode controls the glide path in the approach
c) Special modes are used to control the heading and the altitude
d) All of them are false
3. The automatic flight control system
a) It stabilizes, maneouvers, and controls automatically the plane
b) It responds automatically to inflight emergencies
c) It does not need any supervision by the flight crew
d) All of them are true
4. The closed loop control of an AFCS:
From an error signal, another signal is generated to act in the way of correcting the error
It does not need a servomotor
The feedback loop moves the control surface
5. According to the AFCS
Two axes AFCS can perform automatic landings
Single axis AFCS only control pitch movement (elevators)
Three axes AFCS controls pitch, roll and yaw
Two axes AFCS controls pitch and yaw to maintain navigation
6. The AFCS also:
It can detect a dutch roll condition, but the pilot is the only one who can correct it
The tuck under condition system is only applied on supersonic flights
It contains a flight envelope protection
The yaw damper is used to limit the load factor of some planes
