ATZ
Aerodrome traffic zone
An ATZ extends from the surface to a height of 2000’
above aerodrome level (aal).
Centred on the mid-point of the longest runway.
Radius of either 2 or 2.5 nm. If the longest runway is
1850m or less in length, radius is 2 nm, over 1850m 2.5
nm.
If the end of any runway is less than 1.5 nm from the edge
of the ATZ, its radius is usually extended to 2.5 nm.
An ATZ at a civil aerodrome does not exist outside the
notified hours of operation of the A/G, AFIS or ATC Unit
MATZ
Add picture
Military Air Traffic Zone
Inside the MATZ is an ATZ.
A MATZ will only be open 24 hrs if it serves a
MEDA (Military Emergency Diversion
Aerodrome) or it is has been published as open
24 hrs via NOTAM.
Although it is not compulsory to ask permission
before entering a MATZ, permission must
always be sought before entering the ATZ inside
Remotely Piloted Aircraft Systems – Flight
Restriction Zone
Add picture
The ANO, as amended, sets out UAS FRZ around Protected
Aerodromes for Unmanned Aircraft.
The shape of the FRZ is constructed by using the airfield’s
existing ATZ.
Runway Protection Zones: A rectangle extending 5Km
from the threshold of each runway away from the
aerodrome, along the extended runway centreline, and
500m either side - also to a height of 2000 ft above ground
level;
Additional Zones: In the case where a line that is drawn
1Km beyond the boundary of an aerodrome extends
beyond the Aerodrome traffic zone, and so would not be
protected by it, the flight restriction zone will include a
‘bump’ (the airfield boundary + 1KM) to protect this part
of the aerodrome
OTHER UK AIRSPACE
Temporary Reserved Airspace (Gliders) – TRA(G)
– above FL195
Temporary Restricted Airspace – RA(T)
Temporary Danger Area – TDA
The 250KTS speed limit does not apply to:
• Flights in class A airspace
• IFR in class C airspace
• Exempt VFR in class C airspace or exempt flights
in class D, if authorised by ATCU and MATS Pt 2
• Test flights (specified conditions)
• Flying displays when authorised by the CAA
• Aircraft with CAA written permission
• State aircraft (military aircraft)
Who does FIS apply to??????????
The specific ATS (Basic Service, Traffic Service,
Deconfliction Service, Procedural Service) are
designed to cater for a wide variety of airspace
users and tasks and shall be consistently applied
by controllers/FISOs and complied with by
pilots
The UK Flight Information Services consist of:
• Basic Service;
• Traffic Service;
• Deconfliction Service;
• Procedural Service.
Responsibility of FIS
The UK FIS specify the varying degrees of
traffic information and deconfliction
instructions or advice that controllers/FISOs
pass to assist the pilot in discharging their
responsibility for collision avoidance.
The ATS definitions also include terrain
clearance requirements in order for specific ATS
to be provided and the occasions when
controller/FISOs shall not provide headings or
levels
Basic Service
Similar to a ICAO-mandated FIS, however, traffic
information is only passed if a definite risk of
collision exists.
Available to flights in Class G airspace operating
under both IFR and VFR and in Class E airspace
operating under VFR.
Provided with or without the use of surveillance
equipment.
May be provided by:
ADI | APP | APS |FISO
Basic Service
An ATS provided for the purpose of giving advice and
information useful for the safe and efficient conduct of
flights. This may include weather information, changes of
serviceability of facilities, conditions at aerodromes,
general airspace activity information, and any other
information likely to affect safety. The avoidance of other
traffic is solely the pilot’s responsibility.
Basic Service relies on the pilot avoiding other traffic,
unaided by controllers/ FISOs. It is essential that a pilot
receiving this ATS remains alert to the fact that, unlike a
Traffic Service and a Deconfliction Service, the provider of
a Basic Service is not required to monitor the flight
Traffic Service
Traffic identified using surveillance means and
traffic information given where possible.
Pilots must request the service required.
Definition:
A Traffic Service is a surveillance based ATS,
where in addition to the provisions of a Basic
Service, the controller provides specific
surveillance-derived traffic information to assist
the pilot in avoiding other traffic. Controllers
may provide headings and/or levels for the
purposes of positioning and/or sequencing;
however, the controller is not required to
achieve deconfliction minima, and the pilot
remains responsible for collision avoidance
Deconfliction Service
As per traffic service but IFR only. However advice and information given to enable pilots to avoid other traffic.
Based upon ATCO workload and other limitations.
Definition:
A Deconfliction Service is a surveillance based
ATS where, in addition to the provisions of a
Basic Service, the controller provides specific
surveillance-derived traffic information and
issues headings and/or levels aimed at achieving
planned deconfliction minima, or for positioning
and/ or sequencing. However, the avoidance of
other traffic is ultimately the pilot’s
responsibility
Procedural Service
A non-surveillance based service to IFR only. Advice and information given to enable pilots to avoid other participating IFR traffic, and traffic information on known BS traffic where a confliction exists.
A Procedural Service does not require
information derived from an ATS surveillance
system. Therefore, due to the ability for
autonomous flight in Class G airspace, pilots in
receipt of a Procedural Service should be aware
of the high likelihood of encountering
conflicting traffic without warnings being
provided by ATC.
Pilots flying in the vicinity of aerodromes, ATS
routes, or navigational aids where it is known
that a Procedural Service is provided, are
strongly encouraged to attempt to establish RTF
contact with the notified ATS provider
Definition:
A Procedural Service is an ATS where, in
addition to the provisions of a Basic Service, the
controller provides restrictions, instructions,
and approach clearances, which if complied
with, shall achieve deconfliction minima against
other aircraft participating in the Procedural
Service. Neither traffic information nor
deconfliction advice can be passed with respect
to unknown traffic
UK MILITARY LOW FLYING SYSTEM
Military low flying occurs in most parts of the UK at any height up to 2000 ft above the surface. However, the greatest concentration is between 250 ft and 500 ft and civil pilots are advised to avoid flying in that height band whenever possible.
Military aircraft are considered to be low flying when:
(a) Fixed-wing aircraft, except light propeller-driven
aircraft, are flying below 2000 ft above the surface;
(b) Light propeller-driven aircraft and helicopters are
flying below 500 ft above the surface.
