Introduction of ATC and working Position

Contents

Introduction

The Hong Kong Air Traffic Controllers are usually divided into Two Types which are Radar or Non-Radar Controllers. Controllers are either Tower Controllers or Radar Controllers.

1. Tower Controllers
2. Radar Controllers.

Radar Controllers include Departures, Approach, Terminal, and Enroute Radar Positions

The Three Main Streams are:

1. Tower Stream
2. Approach Stream
3. Enroute Stream

These terminologies will be further discussed in the SPRAT course regarding their Areas of Responsibility (AOR)

ATC Working Positions

Air traffic controllers in Hong Kong work in a team and their Position can mainly be divided into Tower Controllers and Radar Controllers. In the Aerodrome Tower Environment, there are CDC,GMC,AMC,ZNC and FIS. The normal Flow of an Aircraft Departs from an Aerodrome and Land in an Aerodrome is as follows: This is an example of an aircraft departing VHHH

1. Aircraft Contacts CDC for IFR clearance
2. Aircraft Contacts GMC for Push back and Taxi clearance
3. Aircraft Contacts AMC for Take off Clearance
4. Aircraft Contacts DEP for Radar Services which includes Radar Identification and a Higher Altitude
5. Aircraft Contacts EE for Radar Services, Higher Altitude and for radar separation if required

Flow of Handling Outbound Flights

This is an example of an aircraft arriving VHHH from RCAA (Taiwan FIR)

Flow of Handling Inbound Flights

1. Aircraft Contacts EE for Radar Identification, STAR clearance
2. Aircraft Contacts TMC for Flow control, Holding Patterns as aircraft approaches Hong Kong
3. Aircraft Contacts APP for Sequencing, Radar Separation, Fine Speed Control, and Vectoring as Aircraft Enters APP airspace.
4. Aircraft Contacts FAD during 0200-1000, For Finer Sequence inside the Corridor of the APP Path
5. Aircraft Contacts AMC for Clearance to Land
6. Aircraft Contacts GMC for Clearance to taxi to Bay

Clearance Delivery Controller (CDC)

• Hours of Operation: H24
• Operational Hours: 1630-2330 , later absorbed by GMS
• Primary Responsibilities: Issue IFR Clearance

Ground Movement Controller (GMC)

1. GMN

• Hours of Operation: H24
• Primary Responsibilities: Ground Movement in designated Area

2. GMS

• Hours of Operation: H24
• Primary Responsibilities: Ground Movement in designated Area

3. GMM

• Hours of Operation: 00:00-16:00
• Primary Responsibilities: Ground Movement in designated Area

Aerodrome Movement Controller (AMC)

1. AMN

• Hours of Operation: H24
• Primary Responsibilities: Air Movement in designated Area

When RWY 25R is in use, TWY A and TWY B between TWY A1 and up to and including TWY A6 are delegated to AMN.

2. AMS

• Hours of Operation: H24
• Primary Responsibilities: Air Movement in designated Area

On RWY 07R/25L, the area between the CAT II holding points and the runway at K1 and K7 is delegated to AMS for the purpose of glide-path protection.

Zone Controller (ZNC)

• Hours of Operation: H24
• Primary Responsibilities: non-IFR flight within CTR Zone

Flight Information Service (FIS)

• Hours of Operation: 0100-SS(Sunset)
• Primary Responsibilities: FIS, a non-radar service to non-IFR in the Uncontrolled Aircraft Reporting Areas (UCARAs).

Terminal Controller (TMC)

1.TME Terminal East
2.TMS Terminal South
3.TMW Terminal West

• Hours of Operation: H24
  

Detail AOR and Sector Combine Read This...

• Primary Responsibilities: Their task is to stream arrivals from TR sectors into an orderly flow to APP in accordance with relevant instructions from FLC.
  

Enroute Executive (EE)

1. TRE
2. TRK
3. TRS
4. TRC
5. TRV
6. TRW

• Hours of Operation: H24
• Primary Responsibilities: ensure aircraft are maintaining the level assigned by the sector Planner before leaving Hong Kong FIR. Any change in the assigned level must be approved by the sector Planner to ensure accurate transfer data to adjacent ACC/ATCU

Planner (PLN)

• Hours of Operation: Depend on Traffic
• Primary Responsibilities: Manage his/her respective sector by carefully planning traffic flow for EE taking by taking account to equipment status, weather situation, airspace restrictions

Positions	Frequency (MHz)
CDC	122.15
GMN	121.6
GMS	122.55
AMN	118.2
AMS	118.4
ZNC	120.6
FIS	121.0
DEP	123.8
DEH	122.0
APP	119.1
FAD	119.5

Note:

• CDC previously used 121.9 but recently Changed to new frequency AIP SUPP 13/20 WEF 200910
• ATC Frequencies
  • For Enroute (HKAIP ENR 6.7 Hong Kong ATC Sector Boundaries Chart)
  • For Aerodrome (HKAIP AD 2.18 ATS COMMUNICATION FACILITIES)

Air Traffic Management (ATM) and scopes

The objectives of ATS, as stated in ICAO Annex 11, are to

# prevent collisions between aircraft;
#  prevent collisions between aircraft on the maneuvering area and obstructions on that area; note that this objective does not include the apron and ATS in general is not intended to prevent collision with terrain.
#  expedite and maintain an orderly flow of air traffic;
#  provide advice and information useful for the safe and efficient conduct of flights;
#  notify appropriate organizations regarding aircraft in need of search and rescue aid, and assist such organizations as required.

The air traffic control (ATC) service is established to accomplish the first three objectives. While the first and third are universally applicable to all ATC units, the second one is only relevant to aerodrome control units. The fourth objective is covered by the flight information service (FIS) and the last one is the subject of the alerting service.

As seen from the definition, there is a fourth type of ATS, the advisory service. No specific objectives are defined for this type of service. It is considered a temporary measure to facilitate the smoother transition from FIS to ATC.

Air Traffic Management is the aggregation of the airborne functions and ground-based functions required to ensure the safe and efficient movement of aircraft during all phases of operations to enable aircraft operators to meet their planned times of departure and arrival and adhere to their preferred flight profiles with minimum constraints and without compromising agreed levels of safety.

Air Traffic Services (ATS), A generic term meaning air traffic control service which includes :

 area control service
 approach control service and
 aerodrome control service
 air traffic advisory service   
 flight information service 
 alerting service
