Which of the following is an Area Navigation (RNAV) route published for use in the United States?

The correct answer is B, which refers to Q routes. Q routes are specifically designated area navigation (RNAV) routes established in the United States. These routes support the functionality of RNAV procedures and allow for more efficient flight operations, as they enable aircraft to navigate along predetermined paths using GPS or other navigational systems instead of relying solely on ground-based navigation aids.

In contrast, Victor routes are traditional airways primarily based on VOR stations, while Jet routes are high-altitude airways used for fast-moving commercial aircraft and are similarly reliant on conventional navigation aids rather than RNAV. Star routes, which refer to Standard Terminal Arrival Routes, are not classified as RNAV routes; instead, they are specific paths for guiding aircraft safely into terminal airspace. Thus, Q routes stand out as the correct answer within the context of Area Navigation.
