![]() "Bob Crawford" wrote in message ups.com... Along with the dirth of ids there are also apparently restrictions such as "the first and second letters or second and third letters of an identifier may not be duplicated with less than 200 nautical miles separation." A restriction that is often overlooked. About sixty miles southeast of AUW you'll find ATW, continue for another 40 miles or so and you'll find MTW. |

According to http://www.skygod.com/asstd/abc.html "Z" codes have been reserved for "special uses". Ah, I've read that site before but apparently not well enough... I actually thought about whether there were any restrictions on leading Z before I posted, but convinced myself there were not thanks to another nearby airport - Zanesville (KZZV). FWIW, someone pointed out in a similar discussion elsewhere that there's also KNEW in New Orleans, so all the rules are made to be broken I suppose ![]() Your 200nm rule might explain why it wasn't KELI - too close to KERI... so, yeah, maybe they just got sick of trying to make something fit and picked some random letters out of the hat. Maybe someday I'll get to the bottom of it... todd |

I see it was recently changed from O17 to GOO - I have absolutely no idea where they're coming up with the identifiers for these changes. There's an airport near me, Zelienople Municipal Airport, that changed from 8G7 to PJC and I can't figure out any connection. If anyone has any insight I'd love to hear it... todd. The just got weather reporting and have to have all letters. A local airport went from F39 to KGYI when it got AWOS -- Regards, Ross C-172F 180HP KSWI |
