Answer 4

+/- 300ft of the assigned level

Question 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:

Question 6

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

Answer 6

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

Question 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:

Answer 7

1NM

Question 8

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

Answer 8

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.

Question 9

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

Answer 9

The radar identify of the aircraft has been established

Question 10

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

Answer 10

030° magnetic

Answer 11

Code 7500

Question 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:

Answer 12

You are to assume responsibility for your own navigation

Question 13

What does the ATC term “radar contact” signify?

Answer 13

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

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

Question 16

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

Answer 16

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

Answer 18

To conduct surveillance radar approaches

Question 19

The primary duty provided by a radar unit is:

Answer 19

To provide radar separation

Question 20

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

Answer 20

You should maintain that airway by use of your navIgatIon equipment
