Right now we have a few questions with the tag (35, to be precise).
This tag seems to be ambiguous at best (is it a piston engine, a jet engine, a turboprop engine, an electric engine (motor), etc.)

Most of the existing questions seem like they're better under or (possibly with or attached for good measure), so can anyone think of a case where we would want just ?

I really can't see a need for , so if no objections come up I'll retag these posts at some point next week and let die a quiet death.

  • $\begingroup$ I agree with that. The question for which engine was created a turbine tag. Hence it is redundant. $\endgroup$

  • $\begingroup$ @Farhan I have mixed feeling about turbine too - is it a Jet? Turboprop? APU? Turbocharger? (technically the turbocharger is a turbine!) - but I definitely actively dislike engine. $\endgroup$

  • $\begingroup$ I have found one question that makes valid use of the generic engine tag. The rest should be retagged. I already did a couple retags. $\endgroup$

When I wrote the tag wiki for engine, I said that a more specific tag is always better but I did mention some cases where it could be appropriate:

Because there are several very different engine types for aircraft, you should avoid using this tag if you can use a more specific one like or .

Use this tag for questions where the specific engine type isn't important, isn't known or where multiple engine types are being compared.

It looks like none of those cases have really come up yet and of course we can't be sure that they ever will, but I do think there's at least a potential use for it and I suspect that people will keep using it, especially people with little knowledge about aircraft.

But having said that, I think we should focus on actual questions and not on potential ones, so I think it's fine to clean up the existing tags as far as possible and see what happens.
