I vacated the runway eventually, and on the way back to the bay I looked for a fault but couldn't find one. I was filming for the hell of it. Suppose it was just an anomaly. Anyhow, I posted to see if anyone else has experienced it? I need to practice my rto's.Ash Frew.

Probably just the DOORS triggering the Master Caution... Search this forum and you'll find it is mentioned in different topics a couple of times.

Left a door open, not sure if that shows up on the caution panel?I only had the warning without anything showing in the panel and that was was at altitude, I had forgotten to set the cruise altitude on the cabin pressure panel.I'm sure someone will be along with a definitive answer soon :(

Has happened to me a couple of times.I remember reading about this somewhere so I will have a dig for more info, but in my experience, I noticed that when I hit TOGA the FOs caution panel showed a 'door' caption. only after a second or two it disappeared!

Cheers Thomas, Vulcan and Alex. I'll have a look for it. I couldn't be arsed typing what I experienced so I just posted the video. Wish I could delete this topic. Nothing worse than a replicator. Anyway.Ash Frew.

Never mind man, that's what a forum is for ;-)

I read somewhere it is when an overwing exit door is not properly locked into place, I guess it's to add realism? Or I could be wrong. I've experienced the same thing too and the Time I got the mastercaution the ovverhead indicated my Front left and right overwing exits were open (even though then wasn't) then it went off after a few seconds!

If the door is not properly closed the master caution will remain ON.The NG series uses an overwing exit easy to open (and opens to the outside), to prevent operation in flight, during takeoff roll a lock solenoid will lock the door. A delay, a missalignment, a sensor fault or wrongly rigged could trigger momentarily the master caution light.

At first I believed it was some frequency of vibration from the engine acceleration was tripping the door sensors.How it's been explained to me (perhaps Andrea can elaborate), is when t/o power is applied to the over wing door lock pin solenoids engage to pin the door, but it can take a bit for them to get in place...hence, the master caution.Apparently pretty common in cold weather.

The lock will engage with thrust levers advanced more than 50/60%(on ground) (so, at take off roll) and will disengage on landing or in case of power loss (spring loaded to the unlock position for safety reason).I don't know if PMDG simulated it with the entire logic, but, you can test it also with engines off.The requirements are: airplane on ground, throttles advanced more than 50% and at least 5 minutes of aircraft powered up (this to enable all systems).In cold wheater the grease is cold and could add some delays in the actuator.

The video from Skysurfer007 seems to have some add on for ground services, e.g. mooving persons. Can anybody tell me the name of this add on?RegardsCarl Michael

Hello everyone. Thanks for the insight. Appreciated! So is it a bug or a failure modeled by PMDG?To the comment above, I Don't know what video you're talking about, but I think it might be PeopleFlow from Orbx scenery (full terrain experience). Highly recommended. Ngx + orbx = awesomeness if your computer can run them.Ash Frew.

Ash, since the Skysurfer guy (sorry forgot his name) didnt fly in neither Pacific, nor Australia, I highly doubt thats it.My money goes on Aerosoft AES. (or AES lite as a part of more recent Aerosoft sceneries)

Righto mate. Thanks!Ash Frew.

I think the best way of putting it is that it's a bug of the real 737 that is modeled by PMDG ;). I seem to remember reading about this issue somewhere before, possibly in the manuals, but maybe on the forum.
