If you encounter icing at -34 you have bigger problems on you hand then forgetting about engine anti ice!

Regarding Frank's last question, about what happens when we encounter ice crystal clouds (e.g cirrus):Nothing happens, you just zip right thru them. At least I donlt recall the crew taking any precautions the few times I flew jumpseat. However, I do remember reading from somewhere that certain types of cirrus formations (Cirrocumulus) indicate the jet stream's lowest level and turbulence. But my guess is pilots nowadays look more to Wx radar and IFR flying than looking outside!Regards,Victorhttp://www.precisionmanuals.com/images/forum/800driver.jpg

Thanks, Victor.I'm finding it hard to imagine a cloud make of solid ice(in crystalline form). I keep seeing icebergs in the sky! :-)BR,Frank
