TCAS reqoirements?

[LEFT BLANK]

For which aircraft or operations are TCAS required?

Does old aircraft like AN26 have this? HS748?

[Craigie]

I understood that all aircraft with over 19 seats or a certain weight limit must carry TCAS II (or rather ACAS II) in En-Route and controlled TMA airspace throughout the vast majority of Europe if not all (although, it is the responsibility of the Air Traffic Service Providers to issue to AIC mandates for carriage). It may even be more stringent than that. All exemptions as far as I was aware expired on 31st March 2001 so everyone of a particular size should have TCAS II by now. The UK mandate is available somewhere on the CAA web-site for soft copy download.

Just an additional thought / question. Is there any single document available either on-line or in a public bookshop that gives a readable pilots eye view of TCAS/ACAS functionality, it's operation, actions it takes and warnings it gives, pilot interaction with the control panel and the like?

Quote from my Bristol ATPL notes:

The FAA now require aircraft with more than 30 passenger seats, whatever their country of registration, which operate in the USA to carry and use TCAS II. Faced with this fait accompli the JAA has allowed its use but have not yet made its installation mandatory

From Annex 6 to the Chicago Convention:

6.18 Aeroplanes required to be equipped with an airbourne collision aviodance system (ACAS II)

6.18.1 From 1 January 2003, all turbine-engined aeroplanes of a maximum certified take off mass in excess of 15, 000kg or authorised to carry more than 30 passengers shall be equipped with an airbourne collision aviodance system (ACAS II).

6.18.2 From 1 January 2005, all turbine-engined aeroplanes of a maximum certified take off mass in excess of 5,700kg or authorised to carry more than 19 passengers shall be equipped with an airbourne collision aviodance system (ACAS II).

6.18.3 Recommendation.- All aeroplanes should be equipped with an airbourne collision aviodance system (ACAS II)

However, ICAO procedures allowed for the earlier introduction of ACAS requirements through Regional Air Navigation Plans as has happened in Europe for aircraft over 15 000 kg.

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.
