TAF3 Implementation

The Bureau of Meteorology undertook an industry requested review of its Trend Forecast (TTF) services through an extensive, industry-wide consultation process. The aim was to investigate feasible alternative options to TTF that met International Civil Aviation Organization (ICAO) standards.

The key recommendation arising was for a three-hourly updated and responsive aerodrome forecast (TAF3) to replace the current Trend Forecast service (TTF).

On 5 November 2020, the TTF services will cease and TAF3 services will commence. The TAF3 service will provide similar responsiveness, accuracy and operational meteorological information as the TTF.

The major civilian airports affected by this change include Sydney, Melbourne, Brisbane, Perth, Adelaide, Cairns, Canberra, Darwin, Gold Coast and Hobart. At these locations, the TAF3 service will be provided 24 hours a day, seven days a week. The TAF service provided for all other airports will remain unchanged.

Additionally, TAF3 service will be provided at the following military bases when staffed by Defence decision support meteorologists: Williamtown, Nowra, Tindal, Oakey, Townsville, Pearce, Amberley and East Sale. Aerodrome forecasts will revert to the standard TAF services outside of staffed hours, as per the current practice.

A TAF3 Implementation Working Group (TIWG), consisting of a representative group of aviation stakeholders, has been established to oversee this implementation and maximise awareness of the changes.
