Let's say there is a 135 operator who does not have an approved deicing system. In this case the only way to be legal when "[contamination] may be reasonably expected to adhere" would be an outside check no more than 5 minutes prior to takeoff. So far so good.
135.227(a) "No pilot may take off an aircraft that has frost, ice, or snow adhering to ..."
So let's say the pic lands and finds ice adhering to the wing. In this case, let's even go so far as to say that new ice is not adhering. Does the lack of having an approved deicing program mean that there the operator is not allowed to deice? What if glycol is sprayed on? What if it's put in a heated hangar? What if I blow on it until it melts?
I'm trying to find the line because the real question here is, just because the operator doesn't have a deicing/anticing program, does that mean that one is not allowed to deice? Can't use holdover tables, I understand that, but can one go out with a glycol sprayer, remove the ice that adhered to the wing, and then confirm compliance with 135.227(a) and even (b)(1) as necessary, and then take off? Or does the lack of op spec approval somehow preclude that sort of thing, and if it does, reference, please?
