I'm sure that Beagle will be along shortly to keep you all on track. The 10 hours thing seems to come up every few months. I've even raised it myself. They were intending to say, ten hours from your first licence being issued, not on the the issue of LAPL on the transfer to LAPL from NPPL, but that's how it was worded.
Can't see anyone being hanged for taking pax on the first day of using the LAPL if they have 100+ hours of pax carrying since they got their NPPL.
