Is there such a time as 24:00? From: Ken Hohhof Sent: Tuesday, August 6, 2019 2:11 PM To: 'AnimalFarm Microwave Users Group' Subject: Re: [AFMUG] compass bearing factoid
OK, that makes sense. Like I’m never sure if midnight is 0:00 or 24:00.

Airports sometimes have to renumber runways when the local magnetic field changes. Those numbers are the compass bearing to the nearest 10 degrees. So runway 22R would be oriented at 220 degrees, the R designating the right runway of a pair of parallel runways. I was thinking that would a way to number AP sectors, instead of what we do now, which is clockwise starting at AP1 being north. We could have AP0, 9, 18 and 27. Or 0, 6, 12, 18, 24 and 30. But then if the magnetic field of the earth shifted, we’d have to renumber. -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
