For a helicopter with an MOPSC of 15, what two conditions must be met to avoid installing a public address system?

The helicopter must be designed without a bulkhead between pilot and passengers, and the operator must demonstrate that in flight the pilot's voice is audible and intelligible at all passengers' seats.

Does CAT.IDE.H.180 allow an exemption from the public address system requirement for a helicopter with an MOPSC of 20?

No. The exemption applies only to helicopters with an MOPSC of more than nine and less than 20. A helicopter with an MOPSC of 20 is not within that range and therefore must be equipped with a public address system.

What regulatory basis is cited for the public address system requirement in CAT.IDE.H.180?

The requirement is based on Regulation (EU) No 965/2012.
