Mike Cross:
if A is licensed and B is not, a student can log handling exercises on a trip from A to B but not on the way back
Really? How does that square with ANO Art.101(1) which states: "An aircraft to which this paragraph applies shall not take off
or land at a place in the United Kingdom other than: (a) an aerodrome licensed under this Order for the take-off and landing of such aircraft..."
I have heard numerous people arguing that by stopping the lesson just before you join the circuit of the unlicensed field you have somehow changed the purpose of the flight therefore 101 no longer applies but that sounds highly dubious to me. But you seem to be arguing that licensed fields are only required for take-off, not for landing. I'd be interested to hear where you get that from.
