Hi there, Australia is about to introduce Baro-VNAV http://globalairspacesolutions.com/services/baro-vnav/" rel="nofollow - http://globalairspacesolutions.com/services/baro-vnav/ approaches across the country. Can someone confirm that the IFD440 is currently compliant for Baro-Vnav approaches. More Australian specific info can also be found here in the PDF. https://www.casa.gov.au/file/152271/download?token=BO8i_5Lg" rel="nofollow - https://www.casa.gov.au/file/152271/download?token=BO8i_5Lg

The definitive answer needs to come from Avidyne, but I believe the answer is "no". In order for the IFD's to be Baro-VNAV compliant, the AFM would need to state compliance with AC20-138, which it does not as far as I can find. Also, if the IFD's were Baro-VNAV compliant then they would qualify as integrating both Baro-VNAV and GPS/SBAS for LNAV/VNAV capability and along with that comes an annunciation and source selection/prioritisation requirement which I cannot find anywhere in the IFD documentation (perhaps I just missed it). ------------- Vince |

Thanks Vince, sounds sensible. I will be holding off putting in the dual IFD 440's until I get a response from Avidyne.
