The call is..."Hobart Tower, ABC, Baron, IFR, Taxis Cambridge for Launceston, Runway 27, POB 2."
Why "Baron" if your call is to HB Twr? Its on your plan!
One might also argue why "POB 2", as that is also generally on your plan. The only place I fly where they seem to want POB in a call is Townsville - and I figure that's cause its joint RAAF/Civil with RAAF looking after Ground, Tower and Approach!
