On hold for 8+ plus minutes - your call is very important

FSS gets updated information how often? WSI, Jepp, etc. use info updated

The government got pretty much the same data sources as everybody else.
The NOAA generated stuff comes directly. A lot of the processed
maps are actually procured from the same commercial providers.

Nope. WSI, for one, updates with direct feeds, and FSS updates their main
data only at the default time frames. That's why airlines and corporate
operators don't use them. The extended reason they don't is that a
miscalculation can cost them big $$$.

Generally yes, but not exclusively. (See above abour airlines and corporate
operators).

IIRC, WX has invested a lot in processing more frequently updated data.

I was talking to someone at the [I think] Bridgeport FSS (I was on Cape
Cod) a couple of days ago. He was using WSI (or so he said).

There's always one more excuse to avoid making a mistake. Sadly, too many
get made anyway. Don't you think it a little worrisome when you have to
start ignoring reasons why something is a bad idea?

BTW, I did forget about talking to people from the air (ie. for making
PIREPs). Unless DUATS is made a *lot* smarter...
