This is posted on a Flying forum today, but obviously has ramifications for shipping navigation too.
I understand that the CAA are shortly to announce a one off charge to ALL Licence holders of £500.
Apparently this is to cover their costs of converting the ICAO proposed DNAC Navigation System.
The DNAC (Decimal Navigation and Compass) System will apparently simplify all Navigation proceedures in the next decade, by removing the need for deviation, variation and other complex proceedures.
The new system is based on GPS which, of course, can work irrespective of Magnetic, True, or Grid Systems. All Future Navigation will apparenly be based on True North, and a Decimal Compass of only 100 degrees.
There will, of course, be advantages from the new 100 degress latitude and longitude measurements which will be 100 degrees only of latitue measured up from the South Pole to the North Pole and 100 degrees only of Longitude measured East from Greenwich back to Greenwich. No more mixing up East and West or North and South if near the meridians. Also much simpler plotting and measuring etc. and, dare I say it, Exams.
The one off charge is designed to off set costs of mapping, runway re-numbering, Nav Aid re-calibration, Radar re-calibration and numerous other changes which the CAA say will be justified in the long term.
The charge will be collected at the next Licence Validation or Renewal.
