MATS Part 1 Section 1 Chapter 5
Control of VFR Flight
5.3 The minimum services provided to VFR flights in Class D airspace are
specified at Section 1, Chapter 2, paragraph 2. Separation standards
are not prescribed for application by ATC between VFR flights or
between VFR and IFR flights in Class D airspace. However, ATC has
a responsibility to prevent collisions between known flights and to
maintain a safe, orderly and expeditious flow of traffic. This objective i
s met by passing sufficient traffic information and instructions to assist pilots to
‘see and avoid’ each other as specified at Section 3, Chapter 1, paragraph 2.
5.4 Instructions issued to VFR flights in Class D airspace are mandatory.
These may comprise routeing instructions, visual holding instructions,
level restrictions, and information on collision hazards, in order to
establish a safe, orderly and expeditious flow of traffic and to provide for
the effective management of overall ATC workload.
5.5 Routeing instructions may be issued which will reduce or eliminate
points of conflict with other flights, such as final approach tracks and
circuit areas, with a consequent reduction in the workload associated
with passing extensive traffic information. VRPs may be established to
assist in the definition of frequently utilised routes and the avoidance
of instrument approach and departure tracks. Where controllers require
VFR aircraft to hold at a specific point pending further clearance, this is
to be explicitly stated to the pilot.
