The threshold speed of an aircraft is the speed:
Correct answer: B. At which the aircraft crosses the runway threshold on approach
- A. At which the aircraft first begins its take-off roll
- B. At which the aircraft crosses the runway threshold on approach
- C. At which the aircraft leaves the taxiway for the apron
- D. At which the aircraft reaches its cruising altitude
Explanation
Threshold speed refers to the aircraft speed as it crosses the runway threshold during the approach or landing sequence. It is distinct from take-off speed and cruising speed.

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.
