Up the back of the class with Bob
Does no knocker read the JCP before entering this debate?
JCP:
Ensuring that a ‘backup’ network of some 165 navaids remains. This backup network would provide a continuation of navigation services in the event of a GNSS failure. It has been designed to ensure that IFR operations can continue if GNSS is unavailable.
Bing you wonder if
after a few years - all non GPS nav-aids will go, probably radar to ?
Have you considered that the airlines who pay around 99% of Airservices charges might have a say in retention of navaids for the very reason quoted in the JCP?
Radar too? Should there be one of your hypothetical GNSS disruptions (and perhaps for defence reasons) the JCP is about removing EN ROUTE radar and
retaining it in primary areas.
While you and Bob read the JCP, I'll do some lawnmowing. This info today has been most valuable in demonstrating to readers just how far ADS-B covers beyond radar - almost a reminder of John Flynn and his "Mantle of Safety"
