SOP for eating?
Really?
I would hope that pilots would just apply some common sense precautions to the task and pray that nobody will ever feel the need to write one. But of course, that may be asking too much. If you will agree to be careful not to choke or otherwise render yourself incapacatated as a result of dining at the controls, I will promise not to write an SOP to cover this situation. I will also leave it up to your good judgement to decide how much coffee or tea is too much! Good luck up there.
