Is that airfield not a grass strip? And if so, then would I be correct in saying that the DA42 isn't cleared for grass strips?
Question?

If the aircraft "is not cleared" for grass strips, is that the absence of an approval, or a prohibition? Please don't take my question as patronizing, I'm honestly curious about the difference if any in interpretation between operations which are either "not approved" or for which no statement whatever is made, as compared to operations which are specifically prohibited.

In our (well North American anyway) society, you can do whatever you want, unless that act is prohibited by law. If the law does not say you must not, you may. Is flying any different?

I see prohibitions in the DA42 flight manual, but runway surface is not among them. I see a reference to takeoff performance for hard surfaces, but is is silent on other surfaces. By comparison, Cessna does provide a statement about takeoff performace on grass.
