I was holding short for a the departure runway,the captain told me-as I was the PNF- to tell the tower that we are ready for departure,I said to the tower that we are ready for take off,he told me that you can't say that you are ready for take off while you are not on the runway,so he gave me two new rules,before entering the runway I am not allowed to say that I am ready for takeoff instead I should say ready for departure,but if I am on the runway I have to say ready for takeoff ,any reference for that information?!
