midlifesailor – You raise a lot of interesting points. Why would the FAA adopt LORAN for transport aircraft when it already has NDB, VOR and DME aids to navigation with GPS/WAAS now added on top?
I think LORAN receivers
are also not immune to jamming, the military have the capability already. E-LORAN will be no use to existing General Aviation LORAN receivers, so new ones would need to be bought, would GA like that? Will they be mandated to carry ADS-B? Will it be UAT or Mode-S based or both? I see trilateration is also making a bid for radar’s surveillance crown.
I would not bet on the FAA adopting LORAN any time soon. It is ironic that the FAA be paid by congress study a USCG system, LORAN, for aviation; while the mariners happily use the FAA’s WAAS and sales of RTCM differential receivers are dropping. Conversely, the take-up of WAAS by air transport is currently zero. It’s an odd world.
