On descending I hear a sound like a 35 mm camera taking a lot of pictures. Shutters going off in succession.

It assume it's the trim noise.....Eric

That's what it sounds like in the real airplane.Next time you go flying, trim up or down and you should be able to hear the STAB TRIM wheel rotating.Floyd

Thank you. I was wondering about that noise. I thought something was wrong. lol.

Why does the trim make that kind of noise? Is it the servos?

Notice that trim is also automatically applied at 400 RA on an anutoland just like the real mc coy ;-). [h4]Best Wishes,Randy J. Smithhttp://www.precisionmanuals.com/images/forum/betaimg.jpgAMD 64 3200+ | ASUS KV8 DELUXE | GFORCE 5700 ULTRA @535/1000 | WD SATA 80 GIG | 512 DDR 400 |

indeed, this is done to support easier recovering of the aircraft should you have to go around below this altitude... it's modelled in the PMDG version as i've literally 'heard' :)nice thing and nice this baby meets up!

Should I be hearing the trim noise when descending or just during autoland? I've yet to use autoland, and the only trim noise I hear is when I trim manually with AP off.Chris

Autopilot trimming is much more suttle than manual trimming except during Approach and Go-Arounds when flap setting changes are being made and require faster STAB TRIM trimming.Floyd
