What is Navigator?

Navigator is an iPhone and iPad app for precision navigation flights — the kind flown in NIFA-style navigation events, proficiency contests, and personal timing practice, where the goal is to cross each checkpoint on course and on the second.

It does two jobs:

  • In the air, it is a timing instrument. Load your route, enter your planned leg times, and Navigator shows you — leg by leg — whether you are running early or late and what ground speed will put you back on plan.
  • On the ground, it is a scorer. Feed it a route and a track log and it computes timing, course, secret-checkpoint, and fuel penalties, then hands you the numbers and a shareable export.

Everything runs on the device. There is no account, no sign-in, and no server.

The two workflows​

Both paths end at the same place: a scored flight saved to your Flights list, which you can rename, re-grade, and export.

In the air — the live panel.

Navigator's results screen showing planned and actual times, timing, elapsed, course, secret and fuel points, and a total of 388.9 penalty points.

On the ground — the scored result.

What Navigator measures​

A flight is scored as penalty points — lower is better. Points come from five independent sources:

  • Timing points — how far off your planned time each scored leg was, one point per second.
  • Elapsed points — how far off your planned total time the whole flight was.
  • Course points — how far from each intermediate checkpoint you actually flew.
  • Secret checkpoint points — checkpoints you missed or called incorrectly.
  • Fuel points — how badly your fuel estimate missed the fuel you actually burned.

The exact formulas — including the thresholds, the linear course-penalty ramp, and the exponential fuel curve — are written out in the scoring rules.

What you need​

  • An iPhone or iPad running iOS 26.2 or later.
  • A route exported from ForeFlight (or any tool that writes a compatible .fpl).
  • For post-flight scoring: a track log, typically the .kml ForeFlight exports after a flight.
  • Optionally, a panel GPS or ADS-B receiver that broadcasts GDL90 over Wi-Fi, if you'd rather not rely on the iPad's internal GPS.
Navigator is not a navigation system

Navigator is a timing and scoring aid for flights you are already navigating by other means. The iPad sectional map is situational context, not a certified chart: there is no terrain, airspace or traffic awareness. Fly the airplane, navigate with your normal tools, and use Navigator the way you would use a stopwatch.
