A restatement of views ..
(a) the site was set up with the intention that it would be a valued resource for professional pilots
(b) for Tech Log, the emphasis is on technical matters
(c) so long as the discussions bear some relationship to (a) and (b) ... and, at times, that can get a bit tenuous ... they can be introduced, and contributions may be made, by folk from anywhere. Pilots have considerable knowledge in their field .. but are not necessarily the sole source of wisdom in the aviation field.
(d) keep in mind that we have a quite significant proportion of Industry folk here who are not professional pilots .. many don't even hold licences ... but their contributions are of great technical value to the professional piloting community
(e) some folk have a dislike of sorts for the flight simmers .. often that is quite inappropriate ... provided that the simmers offer useful contributions, those contributions, and the folk involved, are valued
