Narrative:

I feel the change in WX format and temperature scale in the united states is unnecessary and a detriment to safety. Admittedly, my window on the big picture is small but this change does not appear to have been in the interest of safety. It is as confusing and makes about as much sense as the renaming of the txwys at the dfw airport. Callback conversation with reporter revealed the following information: this reporter said that the new ICAO standard WX reports are much more difficult to read and interpret than the reports used in domestic united states operations prior to this recent change. The reporter complained about the format in general and the fact that the winds are shown before the cloud cover and visibility. The reporter alleged that this was part of the general movement to have a number of institutions adopt international versus 'american' standards. The reporter claimed to have received little training on reading the new format WX reports, but admitted to having flown internationally and having to interpret this same format. He also said that he had not received a DOT approved booklet on the new format. The reporter did receive a response from his company concerning his complaint and he said that they have agreed that while the format is different, the format is the standard and the company does not think that safety was compromised.

Narrative: I FEEL THE CHANGE IN WX FORMAT AND TEMP SCALE IN THE UNITED STATES IS UNNECESSARY AND A DETRIMENT TO SAFETY. ADMITTEDLY, MY WINDOW ON THE BIG PICTURE IS SMALL BUT THIS CHANGE DOES NOT APPEAR TO HAVE BEEN IN THE INTEREST OF SAFETY.

CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THIS RPTR SAID THAT THE NEW ICAO STANDARD WX RPTS ARE MUCH MORE DIFFICULT TO READ AND INTERPRET THAN THE RPTS USED IN DOMESTIC UNITED STATES OPS PRIOR TO THIS RECENT CHANGE. THE RPTR COMPLAINED ABOUT THE FORMAT IN GENERAL AND THE FACT THAT THE WINDS ARE SHOWN BEFORE THE CLOUD COVER AND VISIBILITY. THE RPTR ALLEGED THAT THIS WAS PART OF THE GENERAL MOVEMENT TO HAVE A NUMBER OF INSTITUTIONS ADOPT INTL VERSUS 'AMERICAN' STANDARDS. THE RPTR CLAIMED TO HAVE RECEIVED LITTLE TRAINING ON READING THE NEW FORMAT WX RPTS, BUT ADMITTED TO HAVING FLOWN INTERNATIONALLY AND HAVING TO INTERPRET THIS SAME FORMAT. HE ALSO SAID THAT HE HAD NOT RECEIVED A DOT APPROVED BOOKLET ON THE NEW FORMAT.
