SCARY. I read here there are so many SOP disciples. No deviation, no rebels. I've flown for a shed load of airlines, and sure enough, as has been told here, the CP decides the SOP's. They have been so varied. That is often one person's opinion. I've come across so much dross as to be painful. Some here quote some moments. CP is not GOD; they sit on the ground; you take the beast into the ether. The SOP's are norm and a minimum. If you feel you'd like to make an extra test to make you feel comfortable with your a/c, and it is according to the manufacturer's allowances, then who is to say you are wrong?
If an extra safety check proves to be negative, inconvenient, and you are chastised for it then you know the true attitude of you company. Time to beware.
