Use of VOR
Hi guys, this is my first post on PPRuNe, site looks great.
I am curious to know the role that VOR currently plays in commercial jet aviation. As GPS is utilized as primary navigation with ILS for landing has VOR taken a more secondary role as a redundancy system or does it still see some use during flight i.e on approach?
Also if there are additional forms of naviagation still being used in this area such as ADF, DME or IRS could you explain in what role these are used.
Thanks for the help!
