I just renewed my Class 4 and Class One Aerobatic, and what I noticed that I had a habit of putting in briefings, out of experience was the story of how
we are playing Russian Roulette every time we fly and it is only the LOOKOUT for other aircraft that only reduces our probability of being yet another
air to air collision.
I stress the stories of one Aircraft at 180kts and another at 120 is a closing speed of 300kts that means if you keep your eyes away from the windshield for more than 5 seconds, that unseen aircraft that popped out of cloud on descent a mile away is going to be in your face in just 5 seconds.
I think TC could throw in some exam questions that include variations of this idea.
