What does "Time on Target" refer to in IFR operations?

"Time on Target" in IFR operations refers specifically to the planned arrival time for an aircraft at a specific waypoint. This concept is crucial for effective air traffic management and ensuring that aircraft arrive at their destinations safely and efficiently. It involves integrating various factors, such as current flight conditions, air traffic control instructions, and route planning, to create an expected time of arrival that aligns with other aircraft and operational protocols. By focusing on a specific waypoint, pilots and air traffic controllers can better manage airspace and maintain separation between aircraft. This precise timing helps in optimizing fuel efficiency, scheduling, and coordination with ground operations upon arrival.
