Aircraft on the runway always has right of way BUT it is polite airmanship to give way to aircraft about to land rather than taxi out in front of them and force a go-around
If it was a 747 on final would there be a different take on the above quote?
If an aircraft is on final you don't enter the runway.
Before anyone jumps on me and states that a 747 would not be at TWB, it is just an example.
