Which of the following is NOT a criterion for aborting takeoff between 80 knots and V1?

The correct choice identifies abnormal tire pressure as a scenario that is not considered a criterion for aborting takeoff between 80 knots and V1. In standard operating procedures for aircraft, the criteria for initiating an abort during takeoff are primarily focused on significant threats to the aircraft’s safety and capability to continue the takeoff safely.

Engine failure, fire or smoke warnings, and windshear represent situations that directly compromise flight safety and typically warrant an immediate response to ensure the aircraft and its occupants are not exposed to undue risk. On the other hand, while abnormal tire pressure may indicate a potential issue, it does not automatically necessitate an abort at speeds below V1 unless it is accompanied by more severe symptoms or if it poses an immediate safety threat. This nuanced distinction is important for pilots to understand, as it helps to prioritize the response to genuine emergencies during critical phases of flight.
