SECTION 4 APPROACH CONTROL AND APPROACH RADAR Flashcards Preview

MATS PART 2 GIBRALTAR > SECTION 4 APPROACH CONTROL AND APPROACH RADAR > Flashcards

Flashcards in SECTION 4 APPROACH CONTROL AND APPROACH RADAR Deck (33):
1

Gibraltar Aerodrome is situated within

the Madrid FIR and the parent ACC is located at Seville.

2

There is no separate Approach Control function at Gibraltar as all documented procedures are based on radar, with the exception of

an Emergency TACAN Let Down Procedure detailed in Chapter 2.21.

3

Inbound IFR flights may carry out

an SRA or Visual Approaches. SRA approaches are documented in the Military AIP for each runway and separate tracks apply to Civil and Military aircraft. These tracks are designed to avoid Spanish LER164.

4

In addition, aircraft are to be routed so as to avoid

over flying Gibraltar and its harbour installations.

5

VFR flights and aircraft carrying out Visual Approaches are responsible for their own

terrain clearance, for self positioning on or adjacent to the defined SRA tracks and must not over fly Gibraltar and its harbour installations. Approach Controllers should identify and monitor these aircraft and be prepared to provide track guidance advice as necessary.

6

Caution should be exercised when providing a radar service to

VFR flights as the pilots may not be qualified, nor the aircraft equipped for instrument flight or SRAs.

7

Approach Radar Rated Controllers at Gibraltar are authorised to provide the following services:

1. Radar Control Service.
2. Traffic and Deconfliction Service
3. Surveillance Radar Approaches
4. Basic Service

8

Approach Radar Controller - General Responsibilities.
APR will carry out the function of Approach Radar using the identifier “Gibraltar Radar”

The Radar Controller’s responsibilities are as follows:

o Identification and Control of outbound IFR aircraft from the point at which they are transferred by Aerodrome Control until they are transferred to Seville ACC or another agency.

o Identification and Control of inbound IFR aircraft from the point at which they are transferred by Seville ACC until they are transferred to Talkdown or Aerodrome Control.

o Provision of a service to VFR inbound and outbound aircraft.

o Provision of a service to overflying traffic.

o Control of aircraft in emergency.

9

Talkdown Controller - General Responsibilities
The Talkdown Controller will, subject to equipment serviceability, carry out Surveillance Radar Approaches using the identifier “Talkdown”.

The Talkdown Controller’s responsibilities are as follows:

Identification and Control of inbound aircraft from the point at which they are handed over by Approach Control until:

A. They are transferred to Aerodrome Control after landing or
B. They are handed back to Approach Control after a Missed Approach.

10

1.5 Combined Function

When a dedicated Talkdown Controller is unavailable APR may carry out SRAs. The APR Controller must not provide any ATC service to any other aircraft during the SRA.

1.9 Provision of ATC Services in Moroccan Airspace – General Procedures

Gibraltar has no approval to provide services in Moroccan (Casablanca FIR) airspace, and has no direct communications with Casablanca. The following procedures must be employed:

19

1.9 Provision of ATC Services in Moroccan Airspace –

1.9.1 IFR Arrivals and Departures

IFR Flights routeing into Moroccan CAS, in receipt of a clearance to enter CAS issued to Gibraltar by Seville ACC, must be transferred, in accordance with the clearance, prior to entering the Casablanca FIR.

Non-airways IFR flights routeing into Moroccan airspace must be transferred to a Moroccan ATSU frequency prior to entering the Casablanca FIR and in sufficient time for the aircraft to obtain clearance to enter CAS.
IFR arrivals within Moroccan CAS in contact with Gibraltar may only be provided with a service once they leave the Casablanca FIR.

20

1.9 Provision of ATC Services in Moroccan Airspace – 1.9.2 IFR Overflights

When Gibraltar Approach becomes aware that an IFR overflight, in receipt of a service, will enter the Moroccan FIR the ATCO is to terminate service prior to entry, and transfer the aircraft to a Moroccan ATSU in sufficient time for the aircraft to obtain clearance to enter CAS if necessary.

21

1.9 Provision of ATC Services in Moroccan Airspace – 1.9.3 VFR Flights.

Gibraltar ATC must not provide a Service to VFR flights within Moroccan Class E Airspace. Service must be terminated prior to entry and the aircraft transferred to a Moroccan ATSU.

Gibraltar may only provide services to VFR flights in Moroccan Class G uncontrolled airspace if appropriate approvals to do so have been received through RAF Operations.

22

Application of ATC Services in Spanish Class D Airspace Radar Control Service.

Radar Control Service is to be provided in Spanish Class D airspace provided individual aircraft are in receipt of a clearance from Seville ACC and operating in accordance with that clearance.

Coordination with Seville ACC must take place in accordance with the procedures contained in GIB/DOC/003

23

Overflights.
When an ATCO becomes aware that an overflight receiving a service will enter Spanish Class D CAS the options are:

• To terminate service prior to entry and transfer the aircraft to the appropriate Spanish ATSU frequency in sufficient time for the aircraft to obtain clearance to enter CAS, or
• To obtain clearance, from Seville ACC to enter CAS, and provide the appropriate service whilst within the airspace.

24

Application of ATC Services in Spanish Class E airspace

Radar Control Service to IFR aircraft
Traffic Service or Basic Service to participating VFR aircraft

25

1.11.1 Procedures for All Flights within Class E airspace:

It is possible that aircraft squawking Seville ACC or Malaga codes may be VFR and not in contact with, or operating under the control of, those agencies. In order to avoid unnecessary avoiding action ATCOs should attempt coordination with Seville ACC as early as possible.

26

1.11.2 Procedures for IFR Flights within Class E Airspace

1. Individual aircraft must be in receipt of a clearance from Seville ACC and operating in accordance with that clearance.
2. Coordination with Seville ACC must take place in accordance with the procedures contained in GIB/DOC/003.

27

Unknown Aircraft

Class E airspace is not a known traffic environment. In this context an unknown aircraft is defined as a radar return, which cannot be associated with an aircraft known by APR either through direct communication, or coordination with Seville ACC.

28

When providing a service utilising surveillance-derived data to IFR aircraft within Class E airspace, controllers are to comply with the following regulations concerning unknown traffic:

 Attempt coordination with Seville ACC.
 When SSR Mode C derived information indicates that the unknown traffic is above the limits of the class E airspace, in class A or D airspace, and provided that at least 1,000ft separation is evident, the radar responses may be allowed to merge. Traffic information need not be passed.
 If lateral separation does not exist and SSR Mode C derived information indicates that the unknown traffic is within or below the limits of the class E airspace, and less than 5,000ft vertical separation is evident, then avoiding action must be passed followed by traffic information.
 When taking lateral avoiding action, the controller is to pass instructions aimed at achieving standard separation of 5nm.

29

IFR Overflights.
When an ATCO becomes aware that an IFR overflight receiving a service will enter Spanish Class E CAS the options are:

• To terminate service prior to entry and transfer the aircraft to the appropriate Spanish ATSU frequency in sufficient time for the aircraft to obtain clearance to enter CAS, or
• To obtain clearance, from Seville ACC, to enter CAS, and provide the appropriate service whilst within the airspace.

30

1.12 Application of services by Gibraltar ATC in Spanish and Moroccan Class G airspace

In accordance with CAP 774.

31

1.13 Allocation of UK Flight Information Services
A pilot shall determine the appropriate service for the various phases and conditions of flight and request that service from the controller. If a pilot fails to request a service, the controller should normally ask the pilot to specify the service they require.

“C/s what service do you require?”
The pilot is required to state the flight rules under which he is operating and whether he requires a Basic, Traffic or Deconfliction Service. The ATCO will confirm which service he is able to provide and advise the pilot of any subsequent changes in the type of service.

32

As non-UK pilots may be unfamiliar with our services it may be necessary to ask supplementary questions. Therefore if the pilot’s response is inconclusive they

should be asked “c/s do you require a radar service?” The controller should use the information received in order to allocate an appropriate service.

If it becomes apparent from the pilot’s responses that he does not understand the services on offer then the Controller may allocate a Basic service.
