In a couple of cases, we've had questions that are asking very specific questions, or for a recommendation of service (FBO, maintenance, aircraft, etc). Currently, the options people seem to use are either "off topic" or "too broad", and sometimes "primarily opinion-based".
Should we improve some of the definitions (specifically of why some questions are "opinion-based" or, perhaps, too specific)? The problem with "off topic" is that it sounds pretty weird when the question is clearly about Aviation. The topic may be inappropriate for SE, but it's still (at least to most new users) "on topic".
In some cases very specific questions may have a lot in common with the identify-this-airport question that was raised earlier on Meta.
