Where Birds Don't Fly

Accidents do not improve safety. They reveal where safety learning arrived too late. In aviation, the idea that accidents improve safety is often repeated in public discourse, but it is fundamentally misleading. Accidents do not improve safety; they reveal where safety learning arrived too late. The improvement in safety that follows an accident is not created by the accident itself, but by the analysis, reflection, and corrective actions that occur afterward. By the time an accident happens, the system has already failed to detect or address the hazards that allowed the event to unfold. The accident becomes a harsh signal that the SMS Enterprise did not learn fast enough from earlier warnings. In this sense, accidents are not engines of progress; they are evidence that learning, communication, and risk management mechanisms were insufficient or delayed.

Changing an instrument arrival procedure to a steeper-than-standard approach slope in order to reduce flight cancellations appears, at first glance, to be a practical operational solution. In a mountain valley airport in the Canadian Rockies, operators often experience persistent weather systems, terrain shielding, and rapidly changing winds. It is understandable that an airport authority may wish to increase reliability and airline confidence by designing an approach that keeps aircraft higher above terrain longer and allows descent closer to the runway threshold. However, modifying an instrument procedure primarily to influence completion rates rather than to preserve stable, predictable flight conditions introduces a systemic safety hazard. Aviation safety depends on standardization, predictability, and pilot expectation. A steeper-than-standard slope undermines all three simultaneously. Standard instrument approach slopes exist for a reason. The typical 3-degree glide path is not a...
