Lear 35 - MACH TRIM Fault

Recommended Posts

I'm not sure this is an FSW issue...posting here to see if others have seen this (and can offer a potential fix).

Last night, I installed the FSFX Immersion pack for the Learjet 35...two flights since installation of that software and I'm now seeing the "MACH TRIM" fault on the annunciator that will not clear.

Can anyone offer a solutions?

Thx, Rob

Hi Rob,

I use the FSFX package as well - and I don't recall any discrepancies with it - other than being a tad pricey for the actual benefit it brought to the aircraft...

I'll try and remember to look when I get in tonight... I'm pretty sure the entire  warning panel is dark in normal flight...

Regards,
Scott

Hello Scott,

Thanks for your reply. I found an older thread here from February last year where someone posted a similar issue...no response to that post for a "fix".

https://www.avsim.com/forums/topic/504262-mach-trim-warning-light/

A little more troubleshooting...I restored the pre-FSFX Aircraft.cfg file to rule out an issue with that software. The issue persisted following my start-up (illuminated "MACH TRIM" warning). Obviously, I started to think it was an issue with my procedure. After a couple more start ups following when the light illuminates, I found that the light illuminates when switching the pitch trim from primary to secondary (to adjust take off trim using the console switches). The light on the annunciator goes back out after the pitch trim switch is returned from secondary to primary. (Since I hide the yokes and do not (yet) have any switches assigned, I was leaving the pitch trim switch in secondary mode)

Issue resolved.

Thx, Rob
