Volcanic Ash Hazard – Considerations for aviation

Volcanic Ash Hazard – Considerations for aviation

OK guys, now to the topic of Volcanic Ash Hazards to aircraft. How much do you rememeber about the effects of volcanic ash / cloud penetration to aircraft? Test your memory with these questions here developed for AESO’s Aviation students this week.

The answers to these questions can be accessed from our media page on this link:http://aviationenglishskills.com/aeso-media-page/

Good luck!

• What is the melting point of volcanic ash?

• Why do significant deposits of volcanic glass coat the high pressure turbine blades?

• Why is volcanic ash / dust so abrasive?

• What can happen to inlet vanes on bypass engines that pass though volcanic ash cloud?

• What other aircraft components / systems may be affected by penetration into volcanic cloud?

• Why can’t volcanic ash cloud be picked up by airborne weather radar?

• What is significant, (in the context of volcanic ash hazard) about engine temperatures around ‘flight idle’ setting.?

• Globally, where are more than 75% of active volcanoes found?

• How many active volcanoes are there in the world?
