If a pilot is authorized for an intersection takeoff by ATC, what is the pilot responsible for ensuring?

When a pilot is authorized for an intersection takeoff, the pilot's primary responsibility is to ensure that the remaining runway length is sufficient for a safe takeoff. Intersection takeoffs occur when a pilot uses a runway point that is not the full length of the runway, which means that less runway is available than what would be used in a standard takeoff from the beginning of the runway.

The remaining runway length is critical because the aircraft needs enough distance to reach the required takeoff speed and ensure a safe climb out. If the remaining runway is not adequate for the aircraft’s performance capabilities, it could lead to a failure to take off properly, which could be dangerous, especially in terms of obstacle clearance and preventing overruns.

While weather conditions, fuel levels, and obstacle clearance are important considerations for a pilot during any takeoff, the specific responsibility related to an intersection takeoff centers on verifying that the runway remaining is suitable for achieving the necessary speed and performance for takeoff.
