There is no doubt that there are less than perfect outfits out there, but when safety of flight is the issue clarification should be sought from the relevant sources (even these less than perfect operations work to the same technical data as other more seasoned setups). PPRuNe possibly should not be included as such.
Exactly my point!
...As far as technical info in this context is concerned, PPRune should not be used as a source of approved data!
