IVAO United Kingdom - Bristol (EGGD)

Aerodrome Procedures

Bristol

Air Controller

AIR is responsible for all movements on all runways. AIR operates on frequency 133.850

Ground Movement Controller

GMC is responsible for all ground movements on taxiways. GMC operates on frequency 121.925. GMC is also responsible for passing IFR departure clearance to aircraft.

Aerodrome Traffic Monitor (ATM)

Bristol is fitted with an ATM and this can be simulated on IVAO. It has a range of about 15nm and displays SSR labels with mode C read out. The ATM may be used to:

Determine the landing order, spacing and distance from touchdown information of arriving aircraft
Identify departing aircraft and validate the SSR codes.
Monitor the progress of over flying aircraft
Establishing separation between departing aircraft
Pass traffic information
Establish separation in the event of a missed approach
assist in taking corrective action when separation between arriving aircraft becomes less than the prescribed minima.

Wind Shear

When a pilot reports wind shear, this must be passed to inbound and outbound aircraft until the report appears on the ATIS. Reports should contain the following information:

Warning of the presence of wind shear
Height or height band and time the wind shear was encountered
Details of the effect on the aircraft

Braking Action

If there is a cause to believe that braking action is less than good, this must be confirmed and information should be passed to departing and arriving aircraft.
