During the landing roll, when will the aircraft on the cold side of the runway clear the other aircraft over?

The correct answer is that the aircraft on the cold side of the runway will clear the other aircraft once separation is established at a safe taxi speed. This ensures that adequate distance is maintained between the two aircraft during the landing roll, which is crucial for safety.

Establishing separation involves ensuring that the aircraft has enough space to maneuver without risking a collision or creating a wake turbulence hazard. It is important for pilots to remain aware of their surroundings and taxi in a manner that maintains a safe distance from other aircraft on the runway or taxiway.

While touching down is a significant milestone in the landing process, it does not provide the necessary margin for safety until the aircraft has decelerated to a safe taxi speed and has confirmed that separation is adequate. The operation of landing lights or receiving taxi instructions from Air Traffic Control (ATC) are also part of the larger operational context but do not directly address the requirement for establishing safe separation during the landing roll.
