Quentic - can you explain, exactly, how you avoid populated areas in the south of England in a jet flying at several miles a minute... perhaps you could give us definition of "least populated" - last question - do you have a CPL?
FWIW
Least populated: I can't imagine an approach to an airport in the UK, that would pass over more people than that to 27L/R at Heathrow.
CPL: No. PPL(A) expired
