Flying into a FISO airfield, and we're the only ones inbound, nothing in the circuit.
We'd like a straight in approach as we're coming from the west and rwy in use is 07.
We advise we'd like a straight in approach and FISO advises us that an aircraft needs to depart as he has a slot to meet so can we join deadside and circuit... (For completeness, he hasn't yet taxied onto the runway

)
Do I ignore the FISO and land anyway, or do I join deadside and circuit to land? Both options are legal.
