For turbine engine powered airplanes certificated after September 30, 1958, but before August 30, 1959, the clearway extends no less than how far on either side of the extended centerline?

For turbine engine powered airplanes certificated after September 30, 1958, but before August 30, 1959, the clearway extends no less than how far on either side of the extended centerline?

• A. 300 feet.
• B. 500 feet.
• C. 100 feet.
• D. 50 feet.

Answer: (A)

Clearway width is about providing a safe, obstacle-free path for the climb beyond the runway. For turbine engine powered airplanes certificated between September 30, 1958 and August 30, 1959, the regulation required the clearway to extend at least 300 feet on each side of the extended centerline, meaning the area centered on the runway axis must be at least 600 feet wide. This ensures there is enough lateral clearance for a safe takeoff path if the aircraft relies on the clearway while climbing. The other distances do not fit this specific historical requirement: 50 and 100 feet would be too narrow to satisfy safety needs, and 500 feet would exceed the stated minimum for that time period but is not what the regulation specified as the required minimum distance per side.
