What are Q routes in aviation?

Q routes are specifically designed for high altitude operations in aviation and are primarily based on GPS navigation. These routes facilitate the en route phase of flight for jet aircraft and are typically used in the National Airspace System (NAS) for efficient and precise routing at altitudes above 24,000 feet. Utilizing Q routes allows for improved air traffic management, reduced flight times, and enhanced safety through separation of high altitude traffic.

It's worth noting that while low altitude routes are important for various types of aircraft, they do not fall under the classification of Q routes, which are exclusively for high altitude. Similarly, Q routes are not limited to cargo planes, as they are applicable to all jet aircraft within the appropriate altitude range. Visual flight rules (VFR) routes pertain to operations conducted under visual conditions, which is distinctly different from the instrument flight rules (IFR) under which Q routes operate.
