VFR AIRCRAFT- An aircraft conducting flight in accordance with visual flight rules. (See VISUAL FLIGHT RULES.) ...
VFR aircraft are only separated from IFR aircraft within the airspace.
An IFR flight with visual contact on VFR aircraft is allowed to manoeuvre to avoid without regard to an ATC clearance. The radar controller is required to advise you if your target merges with another on the screen.
There are some General Aviation concerns that ADS-B removes anonymity of the VFR aircraft operations.
It is usually ATC's responsibility to position IFR aircraft (rather than VFR aircraft, which navigate their own way visually) so that they can 'establish' on the ILS - to get lined up with the ILS 'localiser' which marks the runway centreline.
In a situation like the ATC would ask the VFR aircraft if they have their traffic in sight and providing the aircraft replied with having traffic ATC would say, 'maintain visual separation from that traffic'.
Controlled Airspace - A generic term including all airspace classes in which ATC services are available. VFR aircraft may operate without ATC contact in most controlled airspace as long as weather conditions will permit them to see and avoid ...
Does not imply that all flight is under ATC control. VFR aircraft may operate without ATC contact in most controlled airspace as long as weather conditions will permit them to see and avoid other aircraft.
TERMINAL RADAR SERVICE AREA (TRSA) - Airspace surrounding designated airports wherein ATC provides radar vectoring, sequencing, and separation on a full-time basis for all IFR and participating VFR aircraft.
Terminal Radar Service Area (TRSA): A specified area around a terminal in which participating VFR pilots are provided separation from other participating VFR aircraft and IFR aircraft.
aircraft operating on IFR flight plans within controlled airspace and principally during the en route phase of flight. When equipment capabilities and controller workload permit, certain advisory/assistance services may be provided to VFR aircraft.
plans, generally by centers, when these aircraft are operating between departure and destination terminal areas. When equipment, capabilities, and controller workload permit, certain advisory/assistance services may be provided to VFR aircraft.
