Dead-Reckoning Instrument Drill

Nav Computer Trainer

Mission Briefing

Three instruments, one nav computer. Each round shows two readings per instrument — work out how they relate, and pick the right answer before the clock or your fellow instruments demand attention.

  • Altimeter — two altitudes. Find the difference in feet.
  • Compass — two headings. Find the shortest turn — degrees and direction.
  • RPM — two power settings. Find the percent change between them, not the raw difference.
  • Instrument faults happen at random — repair before you can answer that instrument.

A round only counts as correct if all three instruments are answered correctly.
