1. PARAGRAPH NUMBER AND TITLE: 9-2-5. PIREP FORMAT

2. BACKGROUND: The FAA is responsible for providing meteorological data to stakeholders of the NAS. This includes disseminating and distributing observations, forecasts, and warning messages that pertain to volcanic activity including volcanic ash. PIREPs for volcanic activity and volcanic ash are provided to ATC in a specified format which is specified in the AIM. These reports are then forwarded to the Volcanic Ash Advisory Centers (VAAC) and are used to issue volcanic ash SIGMETs. These changes are to comply with new ICAO guidelines as set forth by the International Airways Volcano Watch Operations Group which have been in effect since November 2010. These changes also comply with the NWS Federal Meteorological Handbook (FMH) Number 12, change 2, effective July 1, 2012.

7. Volcanic eruption, ash clouds, and/or detection of sulfur dioxide (SO2) in the cabin.

 

7. Volcanic eruption, ash clouds, and/or detection of sulfur gases: hydrogen sulfide (H2S) or sulfur dioxide (SO2) in the cabin.

(a) If only SO2 is reported, ask the pilot if volcanic ash clouds are in the vicinity.

 

(a) If only H2S or SO2 is reported, ask the pilot if volcanic ash clouds are in the vicinity.

(b) Sulphur dioxide has a sulfur璴ike odor.   (b) The smell of sulfur gases in the cockpit may indicate volcanic activity that has not yet been detected or reported and/or possible entry into an ash璪earing cloud. H2S, also known as sewer gas, has the odor of rotten eggs. SO2 is identifiable as the sharp, acrid odor of a freshly struck match.

8. Volcanic Activity. Volcanic eruption, ash clouds and/or sulfur dioxide are Urgent PIREPs. Reports of volcanic activity must include as much information as possible; for example, the name of the mountain, ash clouds observed and their movement, the height of the top and bottom of the ash clouds, etc.
