Aerodrome Procedures

Air Controller:

AIR is responsible for all movements on all runways. AIR operates on frequency 118.300

Ground Movement Controller

GMC is responsible for all ground movements on taxiways. GMC operates on frequency 121.800

Ground Movement Planner

GMP is responsible for passing IFR departure clearances to aircraft. GMP operates on frequency 121.925. GMP must not clear aircraft for start/push. Once the aircraft has a clearance, they should be instructed to contact GMC for start/push.

Aerodrome Traffic Monitor (ATM):

Birmingham 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.
