Loganair normally require 2000hrs tt, so my guess is that these
vacancies are for Isles of Scilly Skybus or Rockhopper.
All Islander operators are single pilot so the 700hr rule applies, but many operators have AOCs which impose additional hours requirements.
All piston Islanders (and Trilanders for that matter) can be flown on a MEP rating. You only need a type rating for the turbine variants; in this case I suspect that the requirement for a BN2 type rating is a misprint and that actually just want someone current and experienced on type.
Roll on 1000hrs tt so I can go for these jobs!
