What is one characteristic of a 90-degree taxiway turnoff?

A 90-degree taxiway turnoff is characterized by being FAA preferred for runway entry points due to its ability to facilitate the safe and efficient movement of aircraft from the runway to the taxiway system. This design helps minimize the time an aircraft spends on the runway, which is critical for maintaining operational safety and reducing the risk of runway incursions.

The FAA acknowledges that a 90-degree turnoff allows pilots to make sharper turns, helping them quickly clear the runway after landing or prepare for takeoff, effectively boosting operational efficiency at airports.

In contrast, while increased capacity and best for high-speed characteristics may apply under specific conditions or designs, they are not defining features of a 90-degree turnoff. Decreased cockpit visibility can be an issue in many taxiway configurations but is not specific to this type of turnoff, where visibility can actually improve due to the aircraft's orientation while turning. Thus, the FAA's preference underscores the importance of design elements that enhance safety and efficiency in runway operations.
