Current Perth NOTAM:
C277/15 SPECIAL ALTERNATE MINIMA PUBLISHED ON ANY INSTRUMENT APPROACH CHART IS NOT VALID DUE TO NAVAID NOT AVBL PUBLISHED BY SEPARATE NOTAM. REFER CIVIL AVIATION SAFETY AUTHORITY MANUAL OF STANDARDS (MOS 173) TO CALCULATE A REVISED SPECIAL ALTERNATE MINIMA FROM 05 290000 TO 05 290830 1505290000 TO 1505290400 1505290430 TO 1505290830 Do I get a discount on my airnav charges when I calculate my own SPAM? :E |
SPAM notams now too! Spammers never give up do they.
Hey bloggs, you will have to get the FO to do some maths then. Or do you still have your slide rule? (or any other pre-calculator tools) :} ……..ducking for cover:O |
Close your eyes for five years open them and find nothing has changed. Who pays people these days to sit up all night writing drivel. Five years ago it was educated stupidity, now anybody can become an idiot by joining the regulator.

That NOTAM didn't come from the regulator....

Or how about this for YSSY - with that much arse covering, some people must be so well padded they can't sit down!

MOS 173
Calculation of Special Alternate Minima. To calculate Special Alternate Minima: (a) add 500 ft ceiling and 1.5 km visibility to the ceiling and visibility minima of the VHF runway aligned instrument approach procedure which provides the greatest advantage. (b) add 400 ft ceiling and 1.5 km visibility to the ceiling and visibility minima of the VHF runway aligned instrument approach procedure to an alternative runway. (c) when required by paragraph 8.1.10.3, add 300 ft ceiling and 1.5 km visibility to the ceiling and visibility minima of any other straight-in instrument approach procedure which utilises an aid other than those used in paragraphs 8.1.10.5(a) and 8.1.10.5(b) above. 8.1.10.6 The alternative minimum is the highest of those obtained above. Ceiling values should be rounded out to the nearest 50 ft. Visibility values should be rounded up to the next higher kilometre or half kilometre. 8.1.10.7 An extra margin over and above those mentioned above may be added if believed to be necessary because of peculiarities in the local weather patterns and/or difficulties in forecasting. |
