Reversers can be operated in flight!

[Don t moderate me this way 882]

As I was setting the aircraft up for landing, I accidentally feft-clicked the left engine reverse lever and, to my surprise, it opened! If I held the mouse button, the engine would spool up with the reverse open. There were no failures active.

 

 

Is that the secret military version short field special performance kit we are supposed not to talk about?   :ph34r:

Now that you mentioned, I kinda had the impression I was being followed when I went to the supermarket this afternoon. Also, a suspicious black SUV has been parked across the street for hours!

In the 737 for example the reversers can be opened at RA<10 ft.

Same for me when I tried it, only I had to force the thrust lever to idle first. It wouldn't stay there by itself. Keyboard controls don't work in flight, so pressing F2 will not drive the engines into reverse. Then I noticed keyboard inputs don't work any time you have A/T armed. Must be part of how PMDG programmed the A/T system waking itself up.

 

There are supposed to be locks that prevent accidental TR deployment when the aircraft is in flight mode (no weight on the wheels.)  Something isn't right with that.

Yes. In the aircraft there are multiple safety devices both inhibiting the selection of reverse and mechanically locking the reverser to keep it closed. It's not just belt and braces, it's bolted and deadlocked too.

 

It looks as if PMDG have inhibited keyboard operation of reversers in flight. They probably didn't expect people to use mouse control of the reverse levers in flight and haven't inhibited that. In the NGX the reverse levers won't even move in flight let alone get to the reverse baulk.

 

Curious as to how the sim responded as well; would likely be lift disruption, left roll / dive....

In my case no noticeable deviation at all.

 

I know it doesn't, I was wondering if Boeing made it impossible to operate the reverser's in flight why would they need to say in the FCOM that it is prohibited, but then I was thinking why would they make it possible and state in the FCOM it is prohibited?

I think what they mean is it's prohibited to lift the levers into reverse in flight. I.E. don't even try it, just in case. Maybe they think if they overtly prohibit this, pilots won't be tempted to try and do it.

Exactly what I noticed too.
