Ever plan on running an errand on the way home only to arrive home having made no stops? It happens to me all the time. People become conditioned to patterns and trying to do something different leads to mistakes. The same is true when flying. Procedures are developed and implemented to prevent and catch errors. When conditions require a change from the norm, mistakes are more likely to occur.
Its Time For GPS
Key Takeaways:
- Reliance on outdated or non-precision instrument approaches without vertical guidance increases the risk of pilot error and accidents, as pilots are conditioned to routine patterns and deviations become hazardous.
- Modern GPS-based RNAV approaches with vertical guidance (LPV/LNAV/VNAV) offer significant advantages over traditional ILS, including wider availability, lower maintenance costs, and consistent vertical guidance crucial for stabilized approaches.
- Despite the safety and operational benefits, the aviation industry, including Air Traffic Control (ATC) and airlines, has been slow to adopt and prioritize GPS approaches due to ingrained familiarity with older systems, perceived convenience, and investment hesitations.
