A few idle thoughts...
- Basic effects of controls are the same.
- Basic airmanship is the same.
- Circuits are a bit different, powered civil aircraft usually fly a rectangular circuit quite different to glider teaching.
- Speeds, attitudes, differ. For that reason I'd be sure you're reasonably happy with one set (say a couple of solo hours) before embarking upon another otherwise you'll just confuse yourself.
- Look at the NPPL options (
www.nppl.uk.com), they'll all give cross-credit for glider hours and going for any of the NPPL routes will allow you a license to fly unsupervised sooner. If you are in-love with gliding (and why not!) the NPPL(SLMG) might be the way ahead rather than going SEP (mind you there are a few SEP or microlights out there where the difference from an SLMG is somewhat academic anyway).
