I think some of the changes are not good.....watch the accident rate increase.
http://aviationweather.gov/notice/airmet/
1. ALL AIRMETS
The frequency of the hazard occurrence (OCNL and FRQ) will no longer be included.
Trend remarks will no longer be included..
The 6 to 12-hour forecast outlook area will be delineated with high altitude VOR locations preceded with the BOUNDED BY descriptor.
The reason for amending, correcting or canceling an AIRMET will no longer be included.
SIGMET reference statements will not reference the SIGMET hazard. Statements such as FOR AREAS OF POSS SEV TURB and FOR AREAS OF SEV ICE will no longer be included. Instead the statement SEE SIGMET [NAME] SERIES will be used.
2. AIRMET SIERRA
AIRMET IFR: The cause of the visibility restriction will be limited to PCPN, FU, HZ, BR, FG and BLSN.
AIRMET MTN OBSCN: The cause of the obscuration will be limited to CLDS, PCPN, FU, HZ, BR and FG.
3. AIRMET TANGO
AIRMET TURB: The cause of the turbulence will no longer be included.
AIRMET STG SFC WND: The cause and direction of the wind will no longer be included.
LLWS POTENTIAL: Will include a list of the affected states.
LLWS POTENTIAL: Will be delineated using high altitude VOR locations preceded by the BOUNDED BY descriptor.
LLWS POTENTIAL: LLWS information will not include phrases such as BLW 2000 FT or BLW AGL020.
LLWS POTENTIAL: The reason for the LLWS will no longer be included.
4. AIRMET ZULU
AIRMET ICE: The icing type (RIME, MXD and CLR) will no longer be included.
AIRMET ICE: The location of ice with respect to clouds and precipitation (ICGICIP, ICGIP and ICGIP) will no longer be included. Instead, the term ICE will be used.
The freezing level will be defined as the lowest freezing level above ground level or SFC as appropriate.
Freezing levels will be delineated using high altitude VOR locations at intervals of 4000 feet above mean sea level or SFC as appropriate.
The range of freezing levels over the area will be included.
Multiple freezing level areas will be delineated using high altitude VOR locations preceded with the BOUNDED BY descriptor..
