The National Business Aviation Association (NBAA) is stepping up efforts to reduce controlled flight into terrain (CFIT) accidents, pointing to continued concerns over pilot response to cockpit warnings and lapses in situational awareness.
CFIT—an unintentional collision with terrain, water or obstacles while the aircraft remains under control—remains a leading safety challenge. Though relatively rare, such accidents are often fatal.
While airline CFIT rates have declined sharply over the past two decades—largely due to widespread adoption of terrain awareness and warning systems (TAWS)—business aviation has not seen comparable gains. NBAA data shows that from 2017 to 2025, 38 CFIT accidents involving turbine aircraft resulted in 114 fatalities, with most occurring during the enroute and approach phases of flight.
NBAA Safety Committee members say the issue is not a lack of technology, but how pilots interact with it. “The primary limitation is crew response to warnings,” said CFIT project leader Richard Meikle, noting that most business aircraft are already equipped with advanced avionics, including TAWS, head-up displays and integrated autoflight systems.
The committee is now focusing on the human factors behind those responses. A new NBAA survey aims to better understand how pilots react to terrain alerts, with findings expected to shape future training guidance and potential refinements to warning systems.
NBAA is emphasizing scenario-based training, strengthened standard operating procedures and disciplined adherence to TAWS alerts. The association has also expanded its CFIT resource library with additional case studies and simulator-based training tools designed to replicate high-risk scenarios.

Yet recently a number of undershoots in North America - hitting localizer antenna , late for TWS but perhaps EGPWS would help a bit.
Brain fade - shameful, having known the main push behind the warming system: Don Bateman.
