Question

In the NAS only, ________ _______ is required for all unpublished or random RNAV routes.

a) GPS navigation
b) Radar monitoring
c) ATC clearance
d) Traffic separation

Answer 1

In the NAS, GPS navigation is required for all unpublished or random RNAV routes to ensure accurate navigation and adherence to safety standards.

Step-by-step explanation:

In the National Airspace System (NAS) only, GPS navigation is required for all unpublished or random RNAV routes. The application of RNAV allows aircraft to fly on any desired flight path within the coverage of ground-based or space-based navigation aids, within the limits of the capability of the self-contained systems, or a combination of both. Using GPS navigation enhances the accuracy of the aircraft's position, leading to improved safety and efficiency in the airspace. For unpublished or random RNAV routes, which are not predefined airways or standard flight paths, the precision and reliability of GPS are crucial to maintain separation standards and navigate accurately.
