It’s actually coming from a message intended for Support sending that data as it is an unofficial label we reverse engineered inĢ.6.2 of the Aspen software.

If you don't have an Aspen configuration that supports it now (one that sends baro corrected pressure altitude), don't fret, that capability will come along "for free" with Release 10.1.0.0 in the spring. The one that had most people wanting for more is Advisory Glideslope. You can see there are some configurations below that provide that data, and some that don't. The ACUs are essentially a "happy box" or signal interface box.įor features like VSR datablock and Winds datablock and Advisory Glideslope to work, the IFD540 needs baro input (baro corrected pressure altitude and TAS) among other things. EFD + ACU (I called this ACU1 in previous posts) You can see there are three basic configs:Ģ. I've tried to put together a summary table of the various Aspen configurations when connected to an IFD540. There are understandably a number of folks confused with why they do or do not have certain features on the IFD540 when connected to an Aspen EFD.
