Variable spoilers
My first post - hope I chose the correct forum.
I am not a pilot but a very interested flight simmer.
Recently flew YPAD YSSY onboard a B737-800.
I noticed during descent that the spoilers/spoilerons/speed brake or whatever were deployed a different 'settings' sometimes barely raised and at other times raised more fully (but not a full on as when deployed after touchdown). I felt at the time I noticed them that they were being used to slow the aircraft not as spoilerons.
I am wondering firstly does the auto pilot control them.
Are there 'detent' positions on the control lever for different settings?
Thanks
