Sometimes, aircraft think it’s a good idea to not taxi to the very end of the runway. I think a “Please taxi to end of the runway” would be a good command to use. Why?
Let’s say we have a 7,000 foot runway, and a 77W decides to not taxi to the end of the runway, even though you know well enough that it might go off the end of the runway if it takes off from that point. There’s no command to tell them except “Taxi to runway”, which they’ve already did. So for that reason, I think this command would be a good idea.
