Are there any DAP exemptions with regard to Mode S EHS?

An aircraft is considered to be either EHS capable, or EHS non-capable. To be categorised as EHS capable, the aircraft must be able to provide the DAPs that are explained in the Information Paper – Categorisation of Mode S EHS Capable/EHS Non-Capable Aircraft. Operators of EHS non-capable aircraft registering with the ECC will be granted an exemption but are strongly encouraged to supply any of the listed DAPs that are feasible and therefore benefit from the Mode S services that are available. Transmitted DAPs are to comply with the requirements of JAA NPA 21-12a (or the latest issue).
