My copy of CAP371, all be it the 3rd Edition effective 1 May 1990 shows 10.15hrs as does my company FTL's.
Might it "just be" that a couple of companies have made a typo error or has 371 changed?
As far as living 3 hrs away; surely a pilot should consider his obligations to minimise fatigue. I would have thought that one hr. from your "place of rest" should be considered the maximum that an individual should consider.
