TCAS Requirements
ICAO Annex 6 Part I contains Standards and Recommended Practices (SARPs) that Contracting States are expected to use when developing their own legislation, in effect, writing the rules to fit within their laws.
On behalf of its Member States, the Joint Aviation Authorities (JAA) have developed Requirements that are contained within JAR-OPS 1. As the JAA is a facilitating agency, not an 'Authority', it remains with all JAA Member States to incorporate JAR-OPS Requirements into their national legislation. To this end, the dates published in JAR-OPS 1.668 are: 1 January 2000 for commercial air transport aeroplanes with a maximum take-off mass (MTOM) exceeding 15,000 kg or a maximum approved passenger seating configuration (MAPSC) of more than 30; and 1 January 2005 for aeroplanes having a MTOM exceeding 5,700 kg but not more than 15,000 kg, or a MAPSC exceeding 19 but not more than 30.
The 'large aeroplane' requirement was co-ordinated with EUROCONTROL, and most aeroplanes affected by this requirement were modified by the due date. Some were not, but such short-term exemptions as were granted expired more than a year ago. The same requirements were applied also to aeroplanes registered in States other than the JAA when flying into or through EUROCONTROL airspace.
The only standard permitted was and is ACAS II - such as is met by TCAS II Version 7. JAR-OPS 1 recommends that pilots be trained in the use of TCAS in accordance with JAA Temporary Guidance Leaflet No 11, "Guidance for Operators on Training Programmes for the Use of TCAS" which is based upon ICAO Attachment E to State letter AN 7/13.7.2-97/77, reference JAR/AMC.OPS 1.398. Thus, over Europe, all large aeroplanes - passenger or cargo, flying for commercial air transport, regardless as to where they are registered - should be similarly equipped with all crews employed within JAA Member States trained to similar standards.
