Lets remember 11Sept01, when all aircraft were ordered to land inbound to the USA, yet then, or in the days that followed, the GPS signal was not degraded or switched off.
So much for the switch off nonsense.
Now, I have been using GPS as a prime navigation aid for oceanic/long range flights for a rather long time, and in my private airplane as well, for just as long, yet I can count on exactly three times when the GPS signal faded or was not available...and never during an approach to GPS minimums.
Most of the sour grapes about the US GPS system can be traced to the 'not invented here' syndrome.
Not surprised at this at all.
That the USA thought the idea up and implemented same must be very upsetting to some...on the outside.
