Which statement describes the correct criterion for takeoff distance during IFR departure with passengers?

• A. Runway length
• B. Runway length plus stop-way
• C. Runway length plus clearway
• D. Runway length plus taxiway

Answer: (C)

The distance used for takeoff performance on an IFR departure with passengers is the takeoff distance available, and if a clearway exists, that distance is the runway length plus the clearway. The clearway provides extra distance beyond the runway end that the aircraft can use to accelerate and continue the takeoff, helping you meet required climb performance to clear obstacles after takeoff. The stopway, while useful for stopping a takeoff in an aborted attempt, is not counted as part of the takeoff distance available; it is included in the accelerate-stop distance. Taxiways do not contribute to takeoff distance. So the correct criterion is the runway length plus the clearway.
