Key Takeaways:

  • Moving maps significantly enhance aviation safety by reducing navigational workload and improving pilots' situational awareness compared to older navigation methods.
  • Scientific research from the 1980s and 1990s suggests that track-up orientation is superior for "local guidance" (following a flight route), as it avoids mental map rotation.
  • Conversely, north-up orientation is found to be better for "global awareness" tasks, such as understanding position relative to fixed world-referenced points like airports or navaids.
  • Aggregated expert opinion from the research indicates that if only one display orientation could be chosen, track-up would offer the greatest overall benefits with the fewest mental costs, despite the limitations of the studies using older technology.

Expect vigorous debate on how best to orient your moving map. Here, I’ll address that debate about the best orientation. But rather than reiterating all the opinions, I’ll focus on what the published scientific research completed in the 1980s and 1990s had to say on that specific question.
