What does the instruction 'Line up and wait' mean during takeoff operations?

• A. Exit the runway and rejoin the taxiway.
• B. Line up on the runway and wait for takeoff clearance.
• C. Position on the runway to wait for takeoff clearance while staying clear of the aircraft path.
• D. Hold short of the runway and wait for clearance.

Answer: (C)

Line up and wait means you position the aircraft on the active runway itself and hold there, ready for immediate takeoff, while you wait for takeoff clearance. The emphasis is on being on the runway and prepared, but you must stay clear of the aircraft path so you don’t interfere with other operations or the takeoff path. When clearance arrives, you accelerate and depart. This is different from holding short of the runway (you’d be off the runway) and from simply lining up without noting the need to keep clear of the path. It’s about being ready on the runway and not obstructing movements as you await clearance.
