The big problem is not that guys are failing to recognize the deterioriating Wx conditions in front of them or rate of deterioration, but moreso that they are recognizing them and still pressing forward hoping to either beat them or find a good PL spot without having to backtrack. By the time they fully understand the square corner they've put themselves in, its too late options-wise. Granted, there are situations where accidental encounters happen, but often the available PL option wasnt exercised 10 mins prior. But too many times, the inadverent IMC often stems from adverent causal factors.They missed the first step — ACCEPT.
If the pilots perform a good preflight wx analysis, and they still get stuck, they shouldn’t fear FAA/company reprisals. Until we have 100% weather reporting coverage that’s 100% accurate, it’ll happen. It takes the the company to allow (spend $$) for proficiency flying too to maintain the skills.
