Let’s agree to disagree then. I actually really like the fact that most call outs are written black and white. This way, there is no argument possible and less chance of confusion. We have more than 30 nationalities in my company, with some people including myself with a strong accent; It’s very easy to missundestand each other. To give an example, we had an incident where the PF was an instructor with an average english level doing line training and did a non standard call out at acceleration altitude : « Speed Two Five Zero ». The Fo with only few hours on type, undestood « Flaps Zero » but the speed was below S speed so asked the captain: « are you sure ? » and the captain firmly replied: « Yes! » then you had guessed what went wrong. He retracted the flaps. This would have been avoided if the instructor were using standard phraseology. In that case, no speed call out should be made since it’s not part of the FMA. But if you want to call the speed, by our SOPM, it’s : « Two Five Zero KNOTS ». That extra word would had prevented this incident. It’s not complicated to comply with the standard call out. It’s not like there is hundreds of them. When you know them it’s natural. Now lots of people deviate slightly from the callouts, fair enough, I don’t mind as long it’s clear, I really don’t care. I’m trying to stick as much as possible to what’s written in the books cause that’s what my colleagues expect to hear. Of course we don’t have call out for every situation. That’s impossible. For the rest, I just use good airmanship and that’s it.
