Exemptions allowed:

Where aircraft avionics do not permit the extraction and transmission of the full set of downlink aircraft parameters (DAPs). (The list provides the currently available details of aircraft and their capabilities for providing DAPs. This list will be updated on a regular basis)

When aircraft operators show a clear intent to equip their aircraft as soon as practicable after 31 March 2005 but before 30 March 2007 and who experience genuine technical issues or supply problems, causing delays that are beyond their control. In these circumstances, operators may also apply for a partial alleviation from the Mode S Elementary Surveillance requirements in order to install the wiring for Aircraft Identification reporting at the same time as the wiring for Enhanced Surveillance DAPs.
For aircraft that have an out-of-service date before 31 December 2007.

For aircraft conducting flights, under existing rules, for the purpose of flight testing, delivery or for transit into and out of maintenance bases. (These exceptional cases may be granted strictly limited duration exemptions. In recognition of the special nature of such requests they will be processed via alternative channels. Further details will be announced on this site as they become finalised).

For aircraft that intend to conduct only occasional IFR/GAT flights (under 30 hours per aircraft per annum).



The first and last points are the ones that seem most relevant to GA/Permit/Microlight aircraft.

Anyone going to the Information Day in Brussels tomorrow?

GAT are all flights operated in accordance with Civil Air Traffic Procedures.

The other category is Operational Air Traffic (OAT) which are flights operating in accordance with Military Air Traffic Procedures.

I think it is.

The text above refers to Enhanced Mode S, which is for heavy/fast aircraft, but it does mean that an exemptions body has now been set up and it also says that exempt types will be listed.

So does this mean that in due course all rag and tube VFR machines will be exempt? I return to the proverbial Luton Minor or Fred -- how can these be compelled to carry mode S transponders?
