Hello everybody,

I have a question about the PMDG 737 spoilers. When I land they extend, but once I stow my reversers they go down, how do I make keep them extended like it is IRL? Sometimes they stay up (rarely) and most of the time they go down on their own.

And there is me thinking this thread would be tasty news about release of the B737 EFB and maybe the Max model!  

On the spoilers issue, I don't know the technical answer to that, but I have had numerous flights on B737-800's and the spoilers do seem to retract at about the same time reverse thrust is cancelled.

I think at the speed the reverse thrust is cancelled, the spoilers will have a marginal effect anyway, even to assist braking, and the aircraft certainly isn't going back up at that speed (60-80knts?).

Just wondering why you think it is a problem?  Is it just personal preference?

Are you arming the spoilers before landing?

If you don't, they will deploy anyway in the manner you're describing as failsafe, but the proper procedure is to arm them as part of your landing configuration.

They're auto-stowing, which happens when the reverse thrust levers are closed and the forward thrust levers (the normal throttles) are advanced beyond a certain angle.  Most likely you've got your control bindings set in a way where you're stowing your reversers with your throttles advanced off of idle.  This is accurate behavior; as far as the airplane is concerned, you're trying to do a balked landing go around after touchdown, so the spoilers autostow.

The PMDG spoilers do work correctly and will remain fully extended until you stow the speed brake lever at taxi speed.

That explains what I am seeing then, as I have to push hard to get out of the reverse thrust detent and it tends to overshoot and give the thrust a bit of a blip.

I get it! Good one.

I heard a rumor that they were thinking about doing an EFB. Would that be a "spoiler"?

Andreh makes a good point though; my answer was assuming that the spoilers are properly armed before landing.  If they aren't, they will deploy anyway with reverser deployment, but will maybe autostow when reversers closed? Logically, I can't figure out why they'd do that, but it isn't something I've tested either.
