QRH: avoid icing conditions
Hi,
I was reading 737 QRH (online document) and I found this statement "Avoid icing conditions" for certain cases such wing-body overheat or bleed trip off.
First I want to say I am not pilot and I don't know if this document is updated. If I am not mistaken icing conditions mean: TAT below 10C or visible moisture. Here are my questions:
a) How you can avoid icing conditions? Can you predict icing conditions? Can the weather radar give you a hint about icing conditions before you enter a zone with icing conditions?
b) What you will do if you can't avoid icing conditions (with wing anti ice valve closed or no bleed air)?
c) What are the conditions of dispatching an aircraft if the wing anti ice valve is inoperative?
Feedback appreciated.
