This may be just me but I can not figure it out.
Tried to setup my bravo throttle reversers for the 747. I noticed when reverser 2 was operated the speedbrake deployed.
Long story short after removing all key bindings and then operating reverser 2 with the mouse the speedbrake still deployed. Confused and intrigued I then went back to the PMDG 737 and the same thing happened.
Now as I never land without reversers and speedbrake I have not noticed this previously but it seems it may always have been happening.
Any explanations? Have I done something stupid? Does this happen to anyone else.
