3.) UK-ATM-Responsibilities of Aerodrome Control Flashcards
TYPES OF AERODROME CONTROL SERVICES
Aerodrome Control Service
Basic Service
Alerting Service
Responsibility of Aerodrome control:
Write on flash card - slide 6
Aerodrome Control is responsible for, issuing information and
instructions to aircraft under its control to achieve a safe, orderly,
and expeditious flow of air traffic and to:
PREVENT COLLISIONS BETWEEN
a) Aircraft flying in the vicinity of and within the ATZ.
b) Aircraft taking-off and landing.
c) Aircraft and vehicles, obstructions and other aircraft
on the manoeuvring area.
d) Assist in preventing collisions between aircraft on
the apron.
AIR
Air controller has absolute authority over all
movements on active runways and their
access points. (A and B)
GMC
Ground movement controller has authority for
aircraft and vehicles on other areas of the
manoeuvring area and aircraft on the apron (B
and C)
SPECIFIC RESPONSIBILITIES
• Alerting the Emergency Services as per local instructions.
• Informing aircraft under its control of any depletion of RFFS.
• Provide an Approach Control Service when delegated by APP.
• Supplying the following information to APP/APS :
a) Pertinent data on IFR, Special VFR and VFR traffic including
departures, missed approaches and overdue aircraft.
b) Appropriate items of essential aerodrome information.
• Informing the aerodrome operator when it becomes apparent that
there is a deterioration in the state of the aerodrome or associated
facilities for which the aerodrome authority is responsible.
• Initiating overdue action at aerodromes where no approach control
unit is established.
COORDINATION
Aerodrome Control shall co-ordinate with Approach Control:
a) departing IFR flights;
b) arriving aircraft which make their first call on the tower frequency (unless they
are transferred to Approach Control).
Approach Control will co-ordinate with Aerodrome Control:
a) b) c) aircraft approaching to land; if necessary, requesting landing clearance;
arriving aircraft which are to be cleared to visual holding points;
aircraft routing through the traffic circuit.
Approach Control may delegate the responsibility for co-ordination to
Approach Radar Control.
Aerodrome Control shall co-ordinate with adjacent aerodromes to ensure
that the traffic circuits do not conflict
TRANSFER OF CONTROL
Approach control may instruct approaching IFR flights to contact Aerodrome Control before transfer of control has become effective.
Until approaching aircraft are flying with visual reference to the surface, aerodrome control shall not issue any instructions or advice which would reduce the separation established by approach control.
Military aircraft frequently operate into and out
of civil airports for:
Instrument and circuit training
Refuels
Positioning for air displays
Emergency diversions
Trooping flights
Maintenance and air tests
Search and Rescue
NON-DEVIATING STATUS
Notified by CAA Airspace Regulation (AR)
Generally CAT B. - learn AC Priority’s
Aircraft have an operational requirement to
maintain a specific track and level(s) or
a particular route and level(s).
Imperative aircraft not moved from pre-planned
flight path
OTHER FLIGHTS
PIPELINE / POWERLINE SURVEYS
Usually flown low level by helicopter, be aware
of pylons in vicinity of ATZ as flights will follow
these and usually work Aerodrome control.
AERIAL PHOTOGRAPHY
Very common overhead towns and cities and
also landmarks. Will operate for up to an hour in
the vicinity, often on final approach
Other flight
CALIBRATION/ FLIGHT INSPECTION
TYPES OF FLIGHT INSPECTION
Commissioning - before a new aid is brought
into service.
Routine - usually every 6 months to check ILS
calibration. Will brief on arrival but require
numerous approaches with a sterile circuit and
localiser and glide path clear areas.
Special - If performance of a facility is suspect.
Accident/Incident - following an accident/
incident (flight Cat B, others Cat E
CALIBRATION PROCEDURES
Aircraft will operate in VMC but treat as an IFR
flight.
Crew will brief ATC of requirements and
profiles prior to commencement including:
• Description of manoeuvre
• Altitude
• Start range
• Position at which the go-around will
commence
• Details of required protection of nav aids.
Try to give priority as could take days to
complete
