A couple of weeks back there was a click herelot of discussion about the ICDS2000 locking up at one specific airport - Montgomery Field in San Diego, CA (KMYF).
I had some discussion with the folks at ARNAV, and provided them the data surrounding my own experience. They were on it immediately, and now they’ve tracked it down. I’ve been told that the next release, V920G, will contain the fix that is now being developed. (S/W developers know that the hard part is isolating the bug; fixing it is relatively easy).
The bottom line is that the bug is induced by doing something very specific - loading the ILS 28R approach, and then activating VECTORS TO FINAL.
I’ve posted more detail on this on the http://www.cirruspilots.orgCOPA Members Discussion forum.
