FW-190 A-8 auto/manual prop pitch, problem?

[Roland_HUNter]

Hi!

I noticed, if I going on ~500 meter with 100 % throttle, boost on I reach 550 km/h and 1.51 ata, if I switch to manual prop, the 1.51 ata instantly dropping to 1.42.

Its a bug or not?

What is this manual prop you speak of? ?
 

A8 should only be auto prop pitch governed b KG unless it is set to emergency limp home mode, at which case it may have gone to 1.42 ata if you had it at full throttle. 
 

but - You should have no control over the pitch at that point though? Are you able to actually adjust the pitch?

I switched for manual, for testing. And yes I can adjust the pitch, but with manual pitch, as I said, the 1.51 ata is dropping to 1.42.
