Divisions of atc 1. Area Control Service the provision of air traffic control service for controlled flights except for those described in 2 and 3 in order to accomplish objectives of a) and c) of previous definition slide for atc service(slide 7) that is: -preventing collisions between acft & -expediting and maintaining an orderly flow of air traffic : papavasileiou-atm 1 12

• 2. Approach Control Service the provision of atc service for those parts of controlled flights associated with arrival or departure in order to accomplish objectives a) and c) papavasileiou-atm 1 13

3. Aerodrome Control Service the provision of atc service for aerodrome traffic except for those flights decribed in 2. in order to accomplish objectives a), b), c) of atc service definition. papavasileiou-atm 1 14

Provision of ATC Service • a) Area control service: • 1) by an area control centre; or • 2) by the unit providing approach control service in a control zone or in a control area of limited extent which is designated primarily for the provision of approach control service and where no area control centre is established. papavasileiou-atm 1 15

• b) Approach control service: • 1) by an aerodrome control tower or area control centre when it is necessary or desirable to combine under the responsibility of one unit the functions of the approach control service with those of the aerodrome control service or the area control service; • 2) by an approach control unit when it is necessary or desirable to establish a separate unit. papavasileiou-atm 1 16

• c) Aerodrome control service: • by an aerodrome control tower. • Note. — The task of providing specified services on the apron, e. g. apron management service, may be assigned to an aerodrome control tower or to a separate unit. papavasileiou-atm 1 17

• “Separation” generic term - ATC action to keep aircraft in general area such distances apart to reduce risk of collision papavasileiou-atm 1 19

Air Traffic Control Service Responsibility for Control • • • an individual flight will be under control of only one ATC Unit at any time aircraft operating in given block of airspace under responsibility of only one ATC Unit – but control of one/groups of aircraft may be delegated provided co -ordination assured TWR to control persons/vehicles (also towed acft) on manoeuvring area papavasileiou-atm 1 20

Air Traffic Control Service Responsibility for Control • low visibility procedures – persons/vehicles on manoeuvring area restricted to essential minimum. Protection of ILS/MLS sensitive areas for Cat II and Cat III operations • minimum separation between vehicle and taxiing aircraft as prescribed by appropriate ATS authority • for mixed CAT II and Cat III operations, the more restrictive critical/sensitive areas to be protected papavasileiou-atm 1 21

Air Traffic Control Service Responsibility for Control • emergency vehicles responding to aircraft in distress shall have priority over all surface movements • other vehicles shall comply with following rules: – vehicles (including towing aircraft) shall give way to aircraft landing, taking off or taxiing papavasileiou-atm 1 22

Separation -general • If based on position information from acft, generally known as “procedural” separation • If derived from radar source, known as “radar” separation • Considerable difference between two. Ø Radar provides continuous updating of position information, thus separation minima smaller papavasileiou-atm 1 23

ATS Surveillance Services General Procedures papavasileiou-atm 1 31

General Procedures Topics • Identification of aircraft • Position Information papavasileiou-atm 1 32

Identification of Aircraft • Radar system is capable of displaying hundreds of radar targets at any given time; • The controller must be absolutely certain of a particular aircraft’s identity prior to offering radar service to that pilot; • Failure to identify target whenidentified using An aircraft mustabe positively usingcreates either the secondary radar anprimary obviousorsafety hazard. radar system papavasileiou-atm 1 33

Separation Minima • Minimum horizontal separation between aircraft shall be 5 NM or greater as When authorised by the warranted. Appropriate ATS Authority 5 Miles Separation based on the use of ADS-B, SSR and/or PSR position symbols and/or PSR blips shall be applied so that the distance between the centres of the position symbols and/or PSR blips, representing the positions of the aircraft concerned, is never less than a prescribed minimum papavasileiou-atm 1 38

Reduction of Separation Minima • The radar separation may, if so prescribed by the appropriate ATS authority, be reduced, but not below: • 3. 0 NM when radar capabilities at a given location so permit; and • 2. 5 NM between succeeding aircraft which are established on the same final approach track within 10 NM of the runway end. papavasileiou-atm 1 39
