Spinwing.....the SPIFR model 139 has 4 screens...the original 3 screen setup was never accepted by EASA for SPIFR. Agusta had to upgrade to 4 screens and update the FMC software for the 4th axis. That is, an EASA requirement for SPIFR was that the 139 has 4 screens (redundancy) and a 4 axis coupled AP through the FMS.....
Hey there a few very ordinary SPIFR machines in this country....eg. the SA365C (which was never approved by the manufacturer or any regulatory body on the planet other than CASA who approved it for SPIFR even though it is in breach of its own regulations with a 3 inch AI, 2 axis AP single channel and no coupling...go figure???)
So I don't think there should be any problem approving the 139 with more redundancies built in than you can poke a stick at!
