The preferred orientation of an airport runway is primarily determined by the:
Correct answer: D. Prevailing wind direction at the airport site
- A. Average temperature of the pavement
- B. Annual rainfall pattern at the airport site
- C. Distance from the nearest railway station
- D. Prevailing wind direction at the airport site
Explanation
Runways are oriented mainly to allow aircraft to take off and land into the prevailing wind, which improves lift and operational safety. Rainfall, transport access and pavement temperature may affect design but do not primarily determine orientation.

About Transportation Engineering
Transportation engineering covers highway planning and alignment, traffic studies, road geometric design, pavement materials and flexible or rigid pavement construction. It also includes railway, airport and traffic engineering concepts such as sight distance, superelevation, signals, capacity and level of service, distinguishing pavement failure from poor geometric design.
