Thanks for the information. Here's another question:
Since the NOTAM in itself does not convey any useful information, why can't
the FAA's computer do the calculation and show the results in an easily
digestible format? Something like: "GPS navigation may be effected from
xxxxZ to xxxxZ around [location]".

The computer seems to have all the necessary inputs: time of departure, time
enroute, TAS, route, and destination.

Hello All,
What does the following NOTAM mean:

GPS 02/001 GPS PRN 26 OTS WEF 0502082100-0502090900

I know it says "GPS Pseudo Random Noise 26 Out of Service" but what are
its
implications? Does it mean that RAIM is not available during the outage?

Thanks,

-Ali
