- seabass-labrax 4y agoNDB stations, an even older type of radio navigation beacon, also broadcast their identifier like this. I fancy they might even outlast VORs due to how much cheaper they are to operate. The real survivor though might be the ILS (Instrument Landing System): ILS transmitters broadcast their identifier in Morse code, as did the prototypical Lorenz systems, making them very nearly a century old already (Lorenz systems were first installed in the 1930s). ILS approaches are the most common type for commercial aviation in most countries.
- VBprogrammer 4y agoThe one navaid likely to be around for the foreseeable future is DME. Which sounds slightly strange if you know a bit about aviation, you probably know it as slightly subservient to VOR as in VOR/DME. However, taking a number of DME fixes is a common (though slightly outdated) way of updating a fix for an aircrafts inertial navigation system.
