IO540,
Your statement regarding updating the aeronautical chart to make it legal is incorrect.
AIP:
Before using any CAA chart operationally, users must determine what aeronautical changes have taken place since its
validity date and amend the chart accordingly. This will require users to consult all UK AIP amendments issued since the charts validity
date. If in doubt, they should consult AIS Central Office. A list of amendments for the VFR chart series is available on the CAA web
site: www.caa.co.uk/dap/dapcharts
It is not a useable chart unless the relevant updates have been incorporated. The CAA website not only lists all changes but will often have advance warning of future changes.
Other countries will have their own system, many of them will include the hand amendments in the AIP. Jeppesen have a chart notam series updated weekly.

There is a website where you can get coverage quality (RAIM) prediction for a given lat/long location and time, or an IFR GPS can work it out for you. But as I say it varies with date and time.
Will your IFR GPS tell you in advance that sattelite 30 will be u/s from 15:15 tomorrow until 03:15 on 1st March?

I can't hear - the medical limitations for hearing are wrong.
I can't differentiate colours correctly - the medical standards for colour blindness are wrong.
I can't navigate by DR - GPS should be the way to navigate.
Deaf, Dumb and Blind pilots should not be discriminated against
