It's called gaining situational awareness. Unfortunately, Mr. Renslow lacked SA on that fateful evening. So did the pilots if AF 447. Both of those PIC's came from a non CFI environment. Our hands get held in the US 121 environment, but not in the Part 91 environment. Flight Instruction taught me an incredible amount of situational awareness.
