- The 30 hour TAF
- What, When and Where

## What is it?

**In response to requests by long haul operations for better service, the International Civilian Aviation Organization (ICAO) made provisions for a 30-hour Terminal Aerodrome Forecasts (TAF) in Annex 3 for the Meteorological Service for International Air Navigation, Amendment 74. This code change will affect all TAFs worldwide. **
**This TAF format change will likely impact TAF software de-coders worldwide. More specifically, each change group in a TAF will now have a date. This change also applies to states not providing 30-hour TAFs. **
**Meteorological providers/vendors and users should begin to address whether software will work with the new TAF code, and what publications and training will need to be revised to make sure users are equipped. **

## Training and testing... 

**The NWS will be issuing a sample 30 hour TAF on the last Wednesday of each month through the summer. **
**The test TAF will be found under the WMO bulletin FTXX90 KWBC**
**	****	****- The fake site is KABC **
**We also have an agreement with several other countries for using the same WMO ID. For example in Canada, they are offering to use FTXX90 CWAO. **
**This allows the NWS tele-communications gateway to continuously be looking for FTXX90 CCCC. And build a collective with 30 hour test TAFs from any country willing to use the FTXX90 CCCC header. **
**Also the ASB has a 30 hour testbed...where vendors and users can go to download further material and practice TAFs...**
