IFR is Dead - Long Live IFR
It doesn’t take much insight to see where instrument flight is headed. Nonetheless, intrepid editors are supposed to prognosticate on such things, so I’ll give a shot at plucking some of this low-hanging fruit.
It won’t be too long—perhaps 10 years, perhaps longer—before terrestrial navaids will all but disappear. Instead, everything will be RNAV-based, from T and Q Routes replacing today’s Victor and Jet airways to RNAV approaches. Conventional SIDs and STARs will morph into RNAV procedures. Unfortunately, terrain will still require us to fly circling approaches. However, it’s entirely possible that those circling approaches will be charted and in the database, making them little more difficult than a charted arc or hold is today.
