Aerodrome Traffic Monitor (ATM)

Heathrow 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.
