Support for AIRAC Lookup

Open the app and go to the Current tab (iPhone) or Current Cycle (iPad/Watch). You'll see the cycle number, start and end dates, a progress bar, and days remaining.

Use the Search tab, enter a four-digit cycle code (e.g. 2501), and tap Search. Recent searches are saved for quick access.

On iPhone/iPad: go to the Current tab and use the date picker to select any date — the display updates to show the cycle for that date. On Apple Watch: go to Search and select a date.

Long-press your Home Screen, tap the button, and search for AIRAC Lookup. Choose from small, medium, or large widgets. For Lock Screen: long-press your Lock Screen, tap Customize, tap a widget area, and search for AIRAC Lookup.

On your Apple Watch: long-press the watch face, tap Edit, swipe to the complications screen, tap a slot, and select AIRAC Lookup.

Most years have 13 AIRAC cycles (13 × 28 = 364 days). Rarely, a year has 14. Open the Special tab to see which years are affected and why it happens.

No. All AIRAC cycle dates are calculated on your device. The app works entirely offline.
