It's easy to just say "how about a Pioneer 400," however what are the downsides of such a change?
- Presumably it is GA LSA registered only? Can you obtain a CPL in an LSA? (just wondering)
- It only has 2 seats because it's LSA and only the kit built version has 4 seats
- It runs a Rotax 100 hp so fuel might be an issue to supply premium for it, otherwise maintenance increases and can a GA school use premium easily?
- It may have a CSU, however it is an electric unit and not hydraulic as a normal CSU old school aircraft would be
- It has a timber spar and as a result a suitably qualified LAME would be needed to sign it off
- It has fabric on the airframe (I think), so again a suitable LAME would be needed to sign it off
- It doesn't have a mixture control (could be a good or a bad point really), but makes it harder to switch someone over to a 210 afterwards
... not a simple replacement.
