A missed altimeter setting nearly led to a Controlled Flight Into Terrain (CFIT) incident on a Widerøe DHC-8, exposing how weak procedures, high workload, and compliance gaps can undermine aviation safety. This case study shows how CRM breakdowns, ineffective checklists, and technical limitations create systemic risk—and why robust procedures, EASA compliance, and practical safety barriers are essential to turn written rules into real-world protection.
