I'm not quite sure what the state of play is.
Cant comment on the status of HeliSAS for thr R44, or EASA cert status. Re the 206 and 407, Cobham has announced previously that they are working jointly with Edwards & Associates (Bell subsidiary) on the 206 and 407 STC's. I have spec'd this on a new 407 currently being completed for delivery June, subject to the STC being complete. Look for more specific info at HAI next week. Am being told by some insurance types that this system may be seen as a safety device which might result in lower premiums for acft so equipped.
