LORAN-C is used in aviation but generally only for long range oceanic flights. It however is not the same as the NDB/ADF system. Both use low frequency signals, and both are being phased out in aviation, but they are two completely different navigation systems. The ADF is a very simple system which uses a needle that always points to the physical direction of the selected NDB. Using this information and the aircraft's heading, the pilot can determine the heading to the NDB. If you've flown these approaches before, I'm sure you'll know this is why they can be so tricky in certain situations.
LORAN-C (although I've only messed around with it once or twice-hence my lack of knowledge/experience with it) on the other hand, will give the pilot his/her latitude and longitude information pertaining to the flight's selected waypoints and does not involve an ADF or NDB; it does use a computer to process the information being transmitted, its own cockpit display (which isn't an ADF), and it functions on the principle of triangulation. LORAN-C is more like GPS without the level of accuracy or user-friendliness of GPS. There is no such thing as a LORAN approach (it is an RNAV system only), and it is not used in any way during an NDB approach. Not to sound like a know-it-all or anything..... :icon_wink
do you know if your flight experience helped you in getting your acceptance? I've heard lots of different things about this so I was wondering...
