Answer :
Final answer:
Small to medium-size airports typically have nonprecision instrument runways, which offer lateral navigation aids but no vertical guidance, differentiating them from precision instrument and visual runways.The correct answer is b) Nonprecision instrument runway
Explanation:
Small to medium-size airports usually have a nonprecision instrument runway. This type of runway is equipped with navigation aids that provide lateral guidance but not vertical guidance to pilots during approach. Unlike precision instrument runways,
nonprecision runways do not have the sophisticated systems (like Instrument Landing Systems) that offer precise guidance to aircraft for both altitude and alignment with the runway centerline. They are common in smaller airports, supporting general aviation and flights that do not require the exacting standards of larger, commercial airports.
Visual runways and visual approach runways rely solely on the pilot’s ability to maintain visual contact with the runway, which significantly limits their use under poor weather conditions or at night unless supplemented by additional lighting aids. Precision instrument runways, on the other hand, are found at larger airports due to the higher cost and complexity of their navigation equipment.
