Questions for air traffic services surveillance system
Answer the following questions
Test Mode
Training Mode
1.
The minimum radar separation to be provided to aircraft established on the localizer course shall be
5.0NM between aircraft on the same localizer course
2.5NM between aircraft on the same localizer course
2.0NM between aircraft on adjacent localizer course
2.
Unless otherwise prescribed by the appropriate ATS authority, the horizontal radar separation minimum prescribed by ICAO shall be
8 NM
3.5NM
5.0NM
3.
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 form "ON" to "STBY"
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
+/-300ft of the assigned level in RVSM airspace
+/-200ft of the assigned level in RVSM airspace
+/-500ft of the assigned level in non RVSM airspace
5.
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
6.
When a RADAR operators says the following to an aircraft: "fly heading 030", the pilot must fly heading
030° compass in still air conditions (thereby flying the compass heading)
030° magnetic in still air conditions (thereby flying the magnetic track)
030° true, in still air conditions (thereby flying the true track)
7.
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
8.
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.
9.
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.
10.
The primary duty provided by a radar unit is
To assist aircraft where navigation appears unsatisfactory
To assist aircraft on the location of storms
To provide radar separation
11.
The Air Traffic Control Services: 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 o prevent collisions with terrain
12.
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
More than 300ft
+/- 300ft
300ft
13.
The aircraft 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
14.
Which code shall be used on mode "A" to provide recognition of an emergency aircraft?
Code 7700
Code 7600
Code 7500
15.
What is meant when departure control instructions you to "resume own navigation" after you have been vectored to an airway?
You should maintain that airway by use of your navigation equipment
Advisors will no longer be issued by ATC
You are still in radar contact, but must make position reports
16.
Which code shall be used on Mode "A" to provide recognition of an aircraft subjected to unlawful interference?
Code 7700
Code 7600
Code 7500
17.
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
3NM
1NM
5NM
18.
All aircraft carrying serviceable transponder shall operate the transponder
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.
Only when the aircraft is flying within airspace where SSR is used for ATS purposes.
19.
Secondary Surveillance Radar (SSR) information may be used alone in the provision of separation between aircraft provided
It can not be used for providing separation
Aircraft identification is established and maintained by use of discrete SSR codes.
Instructions to pilot are acknowledged by him by making specific maneuver(s).
20.
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 30° or more
To instruct pilot to execute one or more changes of 10°
To instruct the pilot to execute one or more changes of 45°
21.
Separation based on the use of MLAT position symbols and PSR blips shall be applied so that
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.
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.
