High-flying pilots who often operate in the Flight Levels understand the critical importance of utilizing Enroute High Altitude Charts. These four-color FAA publications present a wealth of important data relevant to IFR ops at & above 18,000 feet, including VHF navigational facilities (frequency, ID, geographic coordinates, and channel), Jet Routes, RNAV Q-Routes, IFR reporting points, select aerodromes, and more need-to-know info for safe flight in Class A airspace.

This H-5 and H-6 chart covers the Central and South Central US, including much of AL, CO, KS, KY, IA, IL, IN, LA, MO, MS, NE, NM, OK, TN, TX, and WY. Uses a scale of 20 nm per inch and is revised every 56 days. Available as a one-time purchase or as a subscription, this is one source of essential flight data that no high-altitude aviator should fly without.
