Which component is a feature of a precision runway but not part of a non-precision runway?

• A. Fixed distance marker
• B. Centerline
• C. Touchdown Zone
• D. Runway designation

Answer: (C)

Touchdown Zone markings are the feature that identifies a precision approach runway. They appear in the first portion of the runway and provide a visual cue for where a stabilized landing should occur when a precision instrument approach, such as ILS, is used. Non-precision runways do not have these TDZ markings because they do not provide the same vertical guidance. Other runway features like the designation and centerline are common to both types, so they don’t distinguish a precision runway from a non-precision one.
