Are slats shy ?

"Spaltklappen" and "Spreizklappen"

Is the radiator and intake flaps, btw....

Polar represents landing flaps at 60 degrees and the influence of the radiator and intake flap settings.

Are you sure? I think Spreizklappen are slotted trailing edge flaps whereas spaltklappen are split flaps. I understood these polars to be from tests of an E-3 for evaluating different alternatives to be included on the F-series as components (in this case different flap designs).

Image for those not familiar with different types of flaps

No, in addition to what CaptainDoggles wrote, the cooler flap is set at 60°.

Only if they open violently, i.e you go from low to very high AOA in a short amount of time. It's basically just like a drawer in your kitchen. If you yank it open it'll slam into the end of its track. If you open it smoothly it won't.

Agree. It'd probably be more like a tactile sensation through the controls.

In that case the noise of the shock will travel inside the wing just to be amplified by the vast empty space of the fuselage (resonance) where there is the pilot. I think that the Bang (if there was one ever) wld be audible above the eng noise (just like AP bullets impact etc...).

Reading modern account of private pilot flying the 109 E shld give the answer.

I checked on a dic but I still might be wrong.

It might be tht the word "reverberation" was more expected here
