Hopefully some of the new players or less experienced / non pilots read this - I’ve been seeing this issue A LOT lately when acting as ATC, seems people are getting confused with the term ‘line up and wait’. I understand 95% of you already know this, but I’m seeing it a lot and wanted to bring it back up.
HOLD SHORT - taxi to, and hold short (behind the line, in simple terms) of the designated runway.
LINE UP & WAIT - taxi ONTO the runway, line up on the centreline, have the aircraft prepared for immediate takeoff, and expect takeoff clearance within seconds.
The old terminology of ‘taxi into position & hold’ was much clearer.
