I think the rule would be more clear if scrambling only applied to island airbases (including England and japan). If sealion is more difficult then so be it. Sealion seems like it is a little too easy anyways.

Repairs take place during “Phase 1: Purchase & Repair Units”. It does not affect movement of the repaired unit in later combat and noncombat move phases in any way.
