Key Takeaways:

Many errors arise from a lack of mode awareness, such as incorrect navigation source selection, autopilot mode engagement, or forgetting to re-engage sequencing in advanced avionics.
Over-reliance on automation (e.g., VNAV, moving maps) without active mental planning, cross-checking with other instruments, or confirming altitude arming leads to reduced situational awareness.
Thorough pre-flight weather briefings, detailed approach briefings, and careful data entry (like correct minimums or courses) are crucial to prevent critical errors.
Pilots should understand the underlying logic and functionality of their avionics and autopilots, rather than just memorizing procedures, to effectively manage unexpected situations and enhance safety.

The FAA and NASA have identified errors commonly made by pilots using advanced avionics. Each of the errors discussed below were unearthed during research in which pilots and flight instructors took part. If we can exorcise these mistakes, our advanced avionics can deliver on their promises of increased safety and utility. Let’s walk through these errors one by one.

Wrong Navigation Source

Center advises you are left of course, but the HSI is centered. Oh, that little NAV source annunciator says you’re on GPS 2 when you thought you were on GPS 1. Set to GPS 2, the autopilot corrects. You resolve to pay that small indicator more attention.
