B777 Auto Anti-Ice
Howdy All - I hope someone can answer this for me.
In the 777 at least, maybe true of other aircraft as well, our EAI and WAI switches stay in Auto during flight. When ice is detected, the AI valves open and hot air flows. However, sometimes we'll see the EAI indication without WAI, so what determines whether the EAI, WAI, or both AI should turn on?
Thanks...
