Are we sure they put enough fuel in it? Fuel is really important for thrust

GPS approaches are very very big capability improvements. There are many downsides to traditional ground based aids. Most major airports still have both, but it usually comes down to cost. Maintaining a GPS approach only involves approach plate amendments for basic approaches. There are GPS based approaches that also use ground based components though. I think GPS is still a massive game changer, particularly for smaller airports that canâ(TM)t afford the ground based aids. So to calibrate your post, itâ(TM)s not about the pilots here, they still use fly in a very similar way, still utilising autopilot. If the interference is only out to 40Nm then it wonâ(TM)t really have an effect on navigation. Inertial Nav will take over the role of GPS as they approach. Worst case, they can be radar vectored.

I hope he gave you a refund, absolutely unbelievable!

While most of us only care about our data being secure whiles itâ(TM)s being transmitted other people have much larger problems. Letâ(TM)s just say itâ(TM)s 30 years away before quantum computers can crack our current crypto. Now youâ(TM)re an organisation trying to transmit very sensitive information about your company. If someone captures that information they will eventually be able to decrypt it when the tools become available. This is why itâ(TM)s important for SOME people to move onto quantum secure crypto and not so important for you.

Considering a significant distribution of the earth still believe the universe was created in 7 days I feel like the error is within tolerances.

Thank you for your sacrifice

You appear to think it needed to be in "airworthy" condition, rather then a "flyable" condition. They are two completely different things. One is orders of magnitude harder to achieve than the other.
