Not sure where I eluded to taking off with frost on the top of the wing, not the point I was trying to make. Not exactly easy to closely analyze frost layers on the top of the wing, so in this case de-icing is prudent.
On the underbelly of the wing and certain very thin patches/very small patches on non-flight control surfaces of the fuselage, it is perfectly safe, acceptable, and not in violation of our company's Op Specs or the FARs.
I appreciate you being an adult about it and not so accusatory, I apologize if I was unclear in anyway.
Thanks.
