As far as prop planes you are right. They do pretty well on flight hours over wildfires. DC-6’s, King King Air 200’s, PBY, S-2’s and others have great track records flying through ash filled sky’s. (mind you,wood ash is a different beast that they are facing now,though I have seen some prop intakes return to base filled with small twigs being injected into the air from strong column driven fires). Even the Evergreen 747 supertanker now being deployed on fires has been retrofitted for “particle impact” on the intake fans. Maybe the airlines should give them a call...Joshhttps://www.blogger.com/profile/08645629430659310315noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-60487519658016935942010-04-18T08:57:46.909-07:002010-04-18T08:57:46.909-07:00I think saying that "propeller" airplane...I think saying that "propeller" airplanes do much better in volcanic ash is giving credit to the wrong part of the airplane. Something like saying this-or-that storm proves/disproves global warming. :) :)<br /><br />I believe it's the type of engine powering the airplane that makes the difference. Turbine engines do very poorly in ash, piston engines can handle ash for a while. Virtually all commercial passenger airplanes of any size have turbine engines, including propeller driven "commuter" size airplanes. It would be impossible to find enough piston engine aircraft to move more than a handful of people.Unknownhttps://www.blogger.com/profile/11741445229316515622noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-24867673494124523532010-04-18T02:10:04.498-07:002010-04-18T02:10:04.498-07:00Thanks for the fascinating Mt.
