Sounds like they are trying to pander to the lowest common denominator - ie: Sports pilots/private pilots that cant be bothered to either learn or use an internationally recognised method of coding met reports.
This is the ICAO standard used by pilot bodies worldwide.
Have to agree with AerocatS2A wholeheartedly.
An ACARS report sent to an aircraft can be 3 or 4 lines (currently) or numerous pages if these clowns at the bottom end of the gene pool have their way.
There is an internationally agreed standard you guys for MET reports.
Its not brilliant, but is effective and allows pilots from anywhere in the world to operate to anywhere in the world and understand the weather at the other end!
If some of you guys want a plain language forecast for Bumf@*k Idaho then petition the bureau of MET and get a user pays service!
