Why do the military use TACANs, why not VOR DME? The compromise was the VORTAC, a colocated VOR and TACAN facility of which all parties can use the DME element By contrast, in the UK, because of the location of military airfields outside the airway structure, the civil and military went their separate ways
Why doesnt civil navigation equipment support TACAN? Today the advantage is for UHF, with equipment being more compact and allowing better performance Why two systems? The divergence between VOR-DME and TACAN results from some competition between civil and NATO authorities at the time the TACAN was designed: The civilian authorities couldn't wait for the TACAN to be operational for use in new
What are the differences between a VOR and a VORTAC? TACAN stands for TACtical Air Navigation, a military system that is similar to VOR but with higher accuracy It works on frequencies between 960 and 1215 MHz Part of the TACAN is DME (Distance Measurement Equipment), which works in the same frequency band The DME used in TACAN is the same that can be used by civil aircraft
How does a TACAN signal change with bearing from the station? In the TACAN system , how does a change in bearing , would translate to a change in the time (or frequency) domain I'll try to elaborate: I'm aware , of the TACAN operation in general let's sa
When was TACAN (or DME?) Y mode introduced? 3 If I understand correctly, originally DME and the equivalent distance measurement aspect of TACAN had only the "X" channels where the pulse pairs are 12 μs apart, and later the "Y" channels were introduced (to TACAN only?) with 30 μs separation When did this happen, in the late 60s 70s era?
What is the difference between a VOR and a VORTAC? A VORTAC (VHF Omni-directional Range Tactical Air Navigation) combines a VOR ground station and a TACAN ground station into a single facility If a VOR equipped aircraft is also equipped with a separate DME unit it will receive distance information between the TACAN ground station (at the single combined facility) and the aircraft
Is it possible for a civilian to use a VORTAC station? Short answer: A VORTAC station combines a VOR-DME and a TACAN It is the result of a cooperation between civil and military worlds to share the same DME (and the navaid place) Civil aircraft use includes accessing the VOR part (civil), the DME part (civil and military), but not the TACAN bearing transponder, said otherwise they access the VOR-DME equivalent, or for what civilians are
