The autobiography that you've provided in this thread indicates that you're an instructor (teacher) with decades of experience, and that you profess to enjoy the learning experience, attempting to get the best out of everyone through thoughtful discussion. I agree. So too would Big Pistons Forever and Pilot Dar and nearly every other user of PPRuNe, many of whom in this thread are heavy hitters, if you asked them. I would enjoy nothing more than learning from yet another professional.
You are quite right to question the need for an emergency brief or its contents. Indeed, asking and answering questions on everything we do in aviation is how we continue to learn after decades of plying our trade, by holding a light to our most sacred assumptions and beliefs. Every single one of us is here to learn. As we've gained experience, we begin to share our knowledge so that others may learn from us. It is always important to remember that a conversation must be clear in its content and intent. A question is asked and a question is answered. Thought provoking questions only remain thought provoking if the questioner provides context for where they are attempting to take their audience. Yet I cannot find in any of your replies thus far any attempt to answer the questions that have been posed to you. These are questions not asked out of malice, but out of genuine interest. When provided an answer that is acceptable to pilots of equal experience as you claim to have yourself, you allude to knowledge the rest of us are seemingly ignorant to, hoping that we will somehow stumble through the dark onto the answer. As seems to be the case, our naivety blinds us. If it may please you, enlighten us on this knowledge that you are seemingly guiding us to, so that we may better instruct our students. We would all be better for it.
Otherwise, I have no other option than to consider the latter half of your input to be as close to trolling as I've seen on these forums in a long while.
