PR - erhm - as the software is free, I am wondering how they make money?
You might subscribe to the enhanced maps but I am not sure I would want to earn a living from a once off payment of £30 or whatever it is now.
Within your vein of flippancy, of course you would have to apply the same rules to the “traditional” navigators who bust CAS, and whilst you are running your simulated GPS outage you should transmit the following message to all aircraft without GPS:
All aircraft are now required to divert to a position which will be passed to you by the unit you are currently working. The position will be up to 60 miles away and you are required to ensure you miss all danger areas and CAS en route, you are also required to inform your unit of your estimate for that position. Your progress WILL be closely monitored. I wonder how many will successfully manage the task??
Of course if you fail the task, and you only have 5 minutes to establish yourself correctly on the new route, all priviliges will be immediately revoked.
Only kidding.
