Q1. Radar identification of a departing aircraft can be achieved if a radar blip is observed within a certain distance from the end of the runway. Identification has to be achieved within:

5 NM

1 NM

3 NM

Correct Answer is:

1 NM

Explanation:

Q2. The primary duty provided by a radar unit is:

To assist aircraft where navigation appears unsatisfactory

To provide radar separation

To assist aircraft on the location of storms

Correct Answer is:

To provide radar separation

Explanation:

Q3. One of the functions ensured by a radar control unit for the provision of approach control service is:

To conduct surveillance radar approaches

To provide instructions in order to reduce separations minima, if accepted by the police

To apply a horizontal separation less than 5 NM

Correct Answer is:

To conduct surveillance radar approaches

Explanation:

Q4. An aircraft in climb or descent is considered to have crossed a level when the SSR mode C derived level information indicates that it has passed this level in the required direction by:

300 ft

plus minus 300 ft

More than 300 ft

Correct Answer is:

More than 300 ft

Explanation:

Q5. Where ADS-B is used for identification, aircraft may be the following procedure:

Recognition of an assigned discrete code, the setting of which has been verified

Asking him to sqwuak assigned mode A code C

Direct recognition of the aircraft identification in an ADS-B label.

Correct Answer is:

Direct recognition of the aircraft identification in an ADS-B label.

Explanation:

Q6. Secondary Surveillance Radar (SSR) information may be used alone in the provision of separation between aircraft provided:

Instructions to pilot are acknowledged by him by making specific maneuver(s).

It can not be used for providing separation

Aircraft identification is established and maintained by use of discrete SSR codes

Correct Answer is:

Aircraft identification is established and maintained by use of discrete SSR codes

Explanation:

Q7. When “Secondary Radar” is used, an aircraft may be identified by one of the following procedures:

To request pilot to set transponder on position “OFF”

Observation of compliance with an instruction to operate transponder from “ON” to ‘STBY” and back to “ON”

To request pilot to switch from “ON” to “STBY”

Correct Answer is:

Observation of compliance with an instruction to operate transponder from “ON” to ‘STBY” and back to “ON”

Explanation:

Q8. Upon intercepting the assigned radial, the controller advises you that you are on the airway and to “resume own navigation”. This phrase means that:

You are to assume responsibility for your own navigation

You are to contact the center at the next reporting point

Radar services are terminated and you will be responsible for position reports

Correct Answer is:

You are to assume responsibility for your own navigation

Explanation:

Q9. An aircraft is considered to be maintaining its assigned level as long as the SSR mode C derived level information indicated that it is within:

plus minus 300 ft of the assigned level

plus minus 200 ft of the assigned level

plus minus 500 ft of the assigned level

Correct Answer is:

plus minus 200 ft of the assigned level

Explanation:

Q10. Separation based on the use of MLAT position symbols and PSR blips shall be applied so that:

The distance between the furthest edges of the position symbols and PSR blips, representing the positions of the aircraft concerned, is never more than a prescribed minimum

The distance between the edges of the position symbols and PSR blips, representing the positions of the aircraft concerned, is never less than a prescribed minimum.

The distance between the centres of the position symbols and PSR blips, representing the positions of the aircraft concerned, is never less than a prescribed minimum.

Correct Answer is:

The distance between the centres of the position symbols and PSR blips, representing the positions of the aircraft concerned, is never less than a prescribed minimum.

Explanation:

Q11. Which code shall be used on mode “A” to provide recognition of an emergency aircraft?

Code 7700

Code 7600

Code 7500

Correct Answer is:

Code 7700

Explanation:

Q12. What does the ATC term “radar contact” signify?

ATC is receiving your transponder and will furnish vectors and traffic advisories until you are advised that contact has been lost

You will be given traffic advisories until advised that the service has been terminated or that radar contact has been lost

Your aircraft has been identified on the radar display and radar flight instructions will be provided until radar identification is terminated

Correct Answer is:

Your aircraft has been identified on the radar display and radar flight instructions will be provided until radar identification is terminated

Explanation:

Q13. Where a “Secondary Surveillance Radar” (SSR) is not available, radar identification may be achieved by one of the following procedures:

To instruct the pilot to execute one or more changes of 450

To instruct the pilot to execute one or more changes of 100

To instruct the pilot to execute one or more changes of 300 or more

Correct Answer is:

To instruct the pilot to execute one or more changes of 300 or more

Explanation:

Q14. The Air Traffic Control Service: do not prevent collisions with terrain:

Except when an aircraft is flying IFR in IMC

Correct, except when an IFR flight is vectored by radar

Wrong, they do prevent collisions with terrain

Correct Answer is:

Correct, except when an IFR flight is vectored by radar

Explanation:

Q15. The minimum radar separation to be provided to aircraft established on the localizer course shall be:

5 NM between aircraft on the same localizer course

2.5 NM between aircraft on the same localizer course

2.0 NM between aircraft on adjacent localizer course

Correct Answer is:

2.5 NM between aircraft on the same localizer course

Explanation:

Q16. The air traffic control unit has reported “radar contact”. What does that mean to the pilot?

The radar identify of the aircraft has been established

The aircraft is subject to positive control

Position reports may be omitted

Correct Answer is:

The radar identify of the aircraft has been established

Explanation:

Q17. All aircraft carrying serviceable transponder shall operate the transponder:

Only when the aircraft is flying within airspace where SSR is used for ATS purposes

As and when required by the pilot

At all times during flight, regardless of whether the aircraft is within or outside airspace where SSR is used for ATS purposes

Correct Answer is:

At all times during flight, regardless of whether the aircraft is within or outside airspace where SSR is used for ATS purposes

Explanation:

Q18. When RADAR operators says the following to an aircraft: “fly heading 030”, the pilot must fly heading:

030 degree true, in still air conditions (thereby flying the true track)

030 degree magnetic

030 degree magnetic in still air conditions (thereby flying the magnetic track)

Correct Answer is:

030 degree magnetic

Explanation:

Q19. Unless otherwise prescribed by the appropriate ATS authority, the horizontal radar separation minimum shall be:

10.0 NM

3.5 NM

5.0 NM

Correct Answer is:

5.0 NM

Explanation:

Q20. What is meant when departure control instructs you to “resume own navigation” after you have been vectored to an airway?

Advisories will no longer be issued by ATC

You are still in radar contact, but must make position reports

You should maintain that airway by use of your navigation equipment

Correct Answer is:

You should maintain that airway by use of your navigation equipment

Explanation:

Q21. Which code shall be use on Mode “A” to provide recognition of an aircraft subjected to unlawful interference?

Code 7600

Code 7500

Code 7700

Correct Answer is:

Code 7500
