keeszondag Posted January 6, 2011 Share Posted January 6, 2011 Geez, is the south pole moving with the same speed and in opposite direction? Will ORBX make a hotfix for the designators on the AUS and NA airports? Link to comment Share on other sites More sharing options...
Sniper31 Posted January 6, 2011 Share Posted January 6, 2011 That IS something to make one ponder....all sorts of pondering that is ... Link to comment Share on other sites More sharing options...
alexf Posted January 6, 2011 Share Posted January 6, 2011 Yeah, but the title is misleading. Tampa is not closing, just repainting signage for new designation (18R to 19R and so on) Link to comment Share on other sites More sharing options...
Dean (PC Aviator) Posted January 7, 2011 Share Posted January 7, 2011 Yes the Earth's magnetic field is slowly reversing! I believe the implications of this will be HUGE over time. Such to the effect that all the global warming hoo-haa will seem like the simplest problem in the world to fix in comparison! Link to comment Share on other sites More sharing options...
Derek McAllan Posted January 7, 2011 Share Posted January 7, 2011 The magnetic poles are always slowly drifting, hardly causes chaos as the drift is slow and predictable. Nav charts (well, nautical ones anyway - I imagine aeronautical are the same) are marked with the deviations and drift from a set date. The magnetic poles have reversed many times in the Earth's history. Cheers, Derek Link to comment Share on other sites More sharing options...
macca22au Posted January 7, 2011 Share Posted January 7, 2011 Alex: global warming is more of a concern than anything to do with the drift of the magnetic pole. The latter is a well-known phenomenon which is reflected on every chart. You're greatest problem is if someone, usually your instructor puts something beside the magnetic compass in your aircraft, and you don't notice it. You then adjust your DI and the fun begins.

Gurdy Posted January 7, 2011 Share Posted January 7, 2011 It is during the reversal when magnetic navigation will be severely impacted. Here is a NASA page that discusses pole drifts and pole reversal. It is interesting stuff.... http://science.nasa.gov/science-news/science-at-nasa/2003/29dec_magneticfield/ or if u are in the mood for some sensationalised bullshit... try this one http://survive2012.com/index.php/geryl-pole-shift.html Link to comment Share on other sites More sharing options...
macca22au Posted January 7, 2011 Share Posted January 7, 2011 Yes I take your point. However we are rapidly developing navigation infrastructure that could well see us independent of the compass in the not so distance future. INR and now GPS are doing that, and I am sure other methods of IFR position cross-checking will be well established. As for runways they could be designated as Blue2 etc rather than by magnetic heading. But life would be different. Just think of the apparent precession we would get on our DI when it is really the pole on the move. Link to comment Share on other sites More sharing options...
CoolP Posted January 9, 2011 Share Posted January 9, 2011 Yeah, but the title is misleading. Tampa is not closing, just repainting signage for new designation (18R to 19R and so on) Maybe they could use displays instead of paint then .."I've landed quite some times on the 19R", "well, not on this 19R".
