Crash One
You, Captain, seem to be of the impression that everyone is somehow blundering through the sky oblivious to everything & that only pure luck is keeping us alive. Please try to believe that this is not the case.
I hope you see this as an attempt to clarify the actual situation & not an attempt to insult you.
Luck is keeping you alive. I have avoided this thread as we had a massive long thread on my very near miss in a twin with a glider in IMC.
I dont intend to start that debate again.
TCAS especially OCAS can give you a false sense of security unless all aircraft are transponding it can lead you to believe there is nothing there when infact there is and the same goes for radar. Radar units do miss aircraft especially non transponding aircraft.
OCAS there is such a mix of everything that you do need to be very careful VMC or IMC. You are relying on the Big sky theory and that can get very small at times.
