Yaw Damper INOP?

[Squishy]

ey all.Quick question:When i use the PMDG cold start config i cannot get the yaw dampers to work properly.I think it's because i messed something up using the IRS buttons?What I do is set them to align and then set the position in the FMC.For some reason i then have to set it to ATT and then to NAV and it works fine. But im not sure if this is the correct way? Yaw damper keeps INOP. Also, i cannot engage the AP (it says no autoland)Thanks!

i think i've figured it out..didnt realize i had to wait 10min for it to align. I changed it to 15sec.Is this somethign real pilots need to do everytime before a flight?

"Is this somethign real pilots need to do everytime before a flight?"This is standard on our real world 747-400's for all flights. I think most, if not all, 744 pilots, prior to a long haul flight will switch off their IRS's and start a 10 minute alignment.Rgds.Q> イアン
