1. The TAF's and Metar's. I get it - they have to be abbreviated to able to send over telex. Problem is the telex died, what, 30 years ago? Why on earth are we still reading an incomprehensible abbreviated piece of text?
Not everywhere. Some palces still use AFTN/SITA. And ACARS sends them in the same format. I see you have an iPhone. Get the Aero Weather APP. It translates them.
2. Why aren't TAF's and Metar's combined? Give me the actual weather and the forecast. All in one. Madness having to look in two different places.
They have different validities. METARs are published every 30 or 60 minutes, TAFs every 3 or 6 hours. You could publish the lates TAF with every METAR, but not everyone would want that, especially environmentalists.
5. Why can't I get weather beamed to me in Europe to some device in the aircraft? I can get it on my Iphone, but not to my aircraft?
You can. It's called ACARS, but it costs.
6. Notams pertaining to your route into the aircraft? Forget it.
Again, by ACARS.
