Air-ground radiotelephone service is a system that allows voice calls and other communication services to be made from an aircraft to either a satellite or land-based network. The service operates via a transceiver mounted in the aircraft on designated frequencies .
Some planes had one or more bulkhead mounted phone stations with cordless handsets that the passengers could use, instead of the multiple wired handsets. Airfone phone calls were usually quite expensive compared to ground-based telephone calls, costing $3.99 per call and $4.99 per minute in 2006.
Low-frequency radio range audio signals: N stream, A stream and combined uniform tone (simulated sounds) The low-frequency radio range, also known as the four-course radio range, LF/MF four-course radio range, A-N radio range, Adcock radio range, or commonly "the range", was the main navigation system used by aircraft for instrument flying in the 1930s and 1940s, until the advent of the VHF ...

An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful ...

Similar to 20 metres, but more sensitive to solar propagation minima and maxima. 17 metres is a WARC band. 15 metres – 21.000–21.450 MHz – 14.28–13.98 m actual; Most useful during solar maximum, and generally a daytime band. Daytime sporadic E propagation (1,500 km / 1,000 miles) occasionally occurs on this band.
