The recently issued FAA Notice JO 7110.616 “adds the detection of sulfur gases (H2S and SO2) in the aircraft cabin,” to questions briefers might ask pilots when soliciting for Pireps. H2S, also known as sewer gas, has the odor of rotten eggs, while SO2 is identifiable as the sharp, acrid odor of a freshly struck match. The FAA plans to report volcanic activity when pilots do not see an ash cloud but do smell sulfur gases within the cockpit and or cabin.
