Hi, I suspect I might have found an error in the Fire protection FAULT light logic. According to the FCOM, with the fire detection loop switches in "normal", failure of both detection loops for an engine causes the FAULT light to illuminate. (No master caution) This means, suppose loops A and B for engine 1 fail -> FAULT light illuminates. In the NGX though, I need to fail all 4 loops (e.g. Loop A and B for engines 1 AND 2) in the FMC/failures menu, for the fault light to illuminate. Please correct me if I missed something. Greetz, Bob

You completely missed my point. I didn't say that I am judging whether the aircraft is in trim or not by sound, of course I am doing that the way you described it (or "pilots do it"). I stated that the sound helps me in a way to get the amount of trim input roughly right the first time without having to correct it 10 times. Fact is though that the delay in the trim sound is odd regardless of how i trim the plane !

Exactly ! Although I cannot fully explain it, hearing the trim has been helpful to counteract the lack of real feel of the yoke. Let's put it this way: When I fly a C152 and have to give a certain input to the elevator, I "know" by experience roughly how many times I have to turn the trim wheel by hand, if it's several times when extending the flaps or just a slight amount when correcting for speed changes for example. If you fly a real B737 (or a full flight sim in my case), you will notice that the trim wheels don't make an even zzzzzzz sound but have a certain "rhythm" which you can translate into wheel revolutions by listening. Holding the trim switches for 2.453 seconds doesn't give you the same feedback as hearing the wheels go around x times. I don't claim this is the only good way to trim, but if it works well and fast for me (and other people apparently as well), it's definitely not wrong ^_^

I searched the forum for this post, the only thing I found from Ryan is that fact the the trim wheels are rotating much slower than in real life is apparently an FSX issue ... not the sound. Weird though that I'm the first one (?) to "complain" about this, I rely on hearing the trim in real life as well as in the sim.

Hi guys, I recently bought the 737NGX and am simply thrilled by the reality level. I will start a B738 TR in real life this summer and use the PMDG 737 to prepare. There's one thing though that puzzles me: when I trim, the trimwheels make about 2 full revolutions before any trim sound is heard. (in other words the trim sound has a delay of about 2 seconds) This is annoying when you make small trim adjustments and you don't know whether the plane is trimming or not. I hope this is not a "feature", at least I couldn't find anything related by searching this forum / Google. I checked the following: - Sound card is set in the CDU Options menu ( I hear all other PMDG sounds OK) - Sound file is OK, no gap at the beginning Can anyone shed light on this issue ? Cheers, Bob
