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

2.0NM between aircraft on adjacent localizer course

2.5NM between aircraft on the same localizer course

5.0NM between aircraft on the same localizer course

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

3.5NM

8 NM

5.0NM

#3. Where ADS-B is used for identification, aircraft may be identified by the following procedure:

Asking him to sqwuak assigned mode A code C.

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

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

#4. 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:

+/-500ft of the assigned level in non RVSM airspace

+/-200ft of the assigned level in RVSM airspace

+/-300ft of the assigned level in RVSM airspace

#5. 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:

+/- 300ft

More than 300ft

300ft

#6. 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).

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

It can not be used for providing separation

#7. 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:

1NM

3NM

5NM

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

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.

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

#9. The aircraft control unit has reported "radar contact". What does that mean to the pilot?

The aircraft is subject to positive control

position reports may be omitted

The radar identify of the aircraft has been established

#10. When a RADAR operators says the following to an aircraft: "fly heading 030", the pilot must fly heading:

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

030° compass in still air conditions (thereby flying the compass heading)

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

#11. Which code shall be used on Mode "A" to provide recognition of an aircraft subjected to unlawful interference?

Code 7700

Code 7600

Code 7500

#12. Upon intercepting the assigned radial, the controller advises you that you are on the airway and to "resume own navigation". This phrase means that:

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

You are to assume responsibility for your own navigation

You are to contact the center at the next reporting point

#13. What does the ATC term "radar contact" signify?

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

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

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

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

To instruct pilot to execute one or more changes of 10°

To instruct the pilot to execute one or more changes of 45°

To instruct the pilot to execute one or more changes of 30° or more

#15. 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"

To request pilot to switch form "ON" to "STBY"

Observation of compliance with an instruction to operate transponder from "ON" to "STBY" and back to "ON"

#16. The Air Traffic Control Services: do not prevent collisions with terrain.

Wrong, they o prevent collisions with terrain

Except when an aircraft is flying IFR in IMC

Correct, except when an IFR flight is vectored by radar

#17. Which code shall be used on mode "A" to provide recognition of an emergency aircraft?

Code 7600

Code 7500

Code 7700

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

To conduct surveillance radar approaches

To apply a horizontal separation less than 5NM

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

#19. The primary duty provided by a radar unit is:

To assist aircraft on the location of storms

To provide radar separation

To assist aircraft where navigation appears unsatisfactory

#20. What is meant when departure control instructions you to "resume own navigation" after you have been vectored to an airway?

Advisors 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

#21. All aircraft carrying serviceable transponder shall operate the transponder:

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

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

As and when required by the pilot.
