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

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

Answer: (D)

Takeoff run is the distance required on the runway to accelerate to liftoff speed. For an IFR departure with passengers, the important point is that this distance must fit within the available runway length. You don’t count spaces beyond the runway—such as clearways or stopways—into the takeoff run itself. Those areas are considered in broader performance calculations (like TODA or ASDA) but they aren’t part of the actual runway distance used to reach liftoff. So the criterion is simply the runway length: you must be able to achieve liftoff within that distance.
