H-3 and H-4 High Alt

High-altitude pilots who regularly operate in Class A airspace understand the critical importance of utilizing Enroute High Altitude Charts. These 4-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 the flight levels. This H-3 and H-4 chart covers the West and Southwestern US, including CA, NV, UT, AZ, and parts of CO, ID, NM, OR, 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-flying aviator should fly without.
