Which type of airways are used to establish en route procedures and rely on a centerline from VOR/VORTACs and intersections?

• A. Victor airways
• B. Jet routes
• C. RNAV routes
• D. Q-routes

Answer: (A)

Victor airways are the low‑altitude, en route paths defined by ground-based navigation aids. The centerline of these airways is charted from VOR/VORTAC radials and fixes at intersections, giving pilots a published path to follow between navigation aids. They are designed for IFR routing from 1,200 feet AGL up to 18,000 feet MSL, using the VOR/VORTAC network to establish and stay on the route.

Jet routes serve high-altitude airways and are defined for use above 18,000 feet, not the typical low-altitude en route navigation described here. RNAV routes and Q-routes rely on GPS/RNAV navigation rather than the traditional VOR centerlines, so they don’t match the description of following a centerline defined by VOR/VORTACs and intersections.
