A holding point is a designated location on an aerodrome where an aircraft must stop and wait before entering or crossing a runway. It is marked both visually on the ground and procedurally in ATC phraseology. Holding points are critical for runway safety and traffic sequencing.
Example:
“OE-ABC, hold short of runway 27 at Bravo.”
Response: “Holding short runway 27 at Bravo, OE-ABC.”
Sometimes a clearance to approach or cross a runway is conditional:
“After landing traffic, line up runway 27.”
The aircraft must wait until the specified condition is met. Conditional clearances must be read back exactly and followed strictly.
