  1. Volcanic asH AND THE PART 121 PILOT Captain Tim Miner Allied Pilots Association National Safety Committee

  2. Outline • What is the guidance given to pilots at American Airlines regarding volcanic ash. • What is the preflight information given to pilots prior to their departure.

  3. Guidance on Volcanic Ash • “Flight in areas of known volcanic activity must be avoided unless specific procedures are in place for monitoring and communication.” • …all SIGMECs and WSI flight plan guidance charts must be reviewed for current status of volcanic activity… (controlling information) • …without internet a review of (text) SIGMECs in DECS (flight plan computer system) is sufficient…

  4. Guidance • “If volcanic ash is reported enroute, the planned flight should remain at least 60 nm clear of the area, and if possible, stay on the upwind side…” • “If volcanic ash is encountered exit as quickly as possible…” (180 degree turn)

  5. Guidance • “Flights shall not be planned or operated to / from an airport when due to volcanic ash, one of the following applies to that airport:” • …it is within closed airspace • …it is closed by local authorities • …has volcanic ash reported in the body (not remarks) of the METAR • …it is within or forecast to be within a SIGMEC issued by WSI where ash exists or is forecasted to the surface

  6. Preflight information • Textual guidance provided by WSI warning areas specific for American Airlines operations. • Static visible images (non scaling) October 30, 2012 picture of “volcanic area number 5” in South America Pink dot represents location of a volcano (not necessarily erupting at the time) At this time ONE volcano here was …?

  7. Conclusions • Given the lack of information and our dependence upon the dispatcher, all AA pilots will err on the side of caution, especially during night or IMC operations. • Keeping away from known plumes by 60 nm and in terminal areas is a must. • “ALWAYS FLY AGGRESSIVELY SAFE!”
