Hallo Herman,I made a clean install and installed the servicepack. Maybe in this proces options got accidentely transplanted to other liveries? Otherwise it doesn't make sense, since I never touched failure option settings. Would it be possible that some 'official' liveries (downloaded from the PMDG site) have failures set to active? I have been playing around a littlebit with the settings, loading other configurations into the FMC to see the difference in equipment and so on. So I wonder, could installing liveries have this effect? All settings are per airframe/tailnumber as I understand it. In real life I have only flown (motor)gliders, so I'm pretty busy studying this magnificent PMDG simulation. I can't handle that, since I only started flying airliners in February this year (yes, default 737). But if you do a clean install with absolutely no previous files, then failures are switched off by default.AndrewI never activated failures sofar.

I can conclude that prior to your reinstall you did not remove some settings and that service based failures were maybe still active as a result of having been set previously.
