John,Thanks for the link. That's a very interesting article.I especially like how Boeing makes up new words, though. Near the bottom of the page under "3. SPECIFIC FLIGHT CREW ACTIONS REQUIRED IN RESPONSE TO ENCOUNTERS... PROCEDURES... 8. Monitor engine exhaust gas temperature..." the general instruction is given:"The flight crew should prevent EGT exceedances."Good word. I'm gonna have to use that some time.:-)Kevin

The 2004 Jeppessen FAR/AIM actually has procedures for flight crews when flying through volcanic ash, and my textbook mentions two times that 747s had quadruple engine failures while flying through the ash!

Looks like I need to bookmark a better online dictionary. Thanks for the link. I gotta tell you I'm still going to use that word before the end of next week on someone... :D Kevin

This true with the 747. At the moment all 4 engines quit, the 747 bacame the worlds largest glider. Fortunatley they did get 2 of the engines started again.

They got 3 of the 4 engines restarted again. In fact for a while all four were restarted but one kept surging so they shut it down again.Apparently they could barely see out the window on approach to Jakarta because the ash had sandblasted the windscreen panels..I think they earned their whole career`s salaries that day! Amazing airmanship.CheersLungsEdit just noticed I didn`t mention the occurrence in question - I`m referring to the BA 742 which encountered Mt Galunggung.

Looks like it is begining to erupt. It will be interesting to see how it affects the air traffic in this area.

Hey JohnSounds like it is the most active its been in nearly 20 years. DO you live close to it? I`m on the other side of the Pacific in NZ. NZ had its last eruption in 1996 when Mt Ruapehu was active. Cheers Rottenlungs
