- For
- UK and European pilots using iPhone or iPad
- Worth noticing
- Holding entries include direct, teardrop, and parallel options, with a north-up diagram and optional wind correction.
Field notes
The listed calculators cover wind and runway crosswind, altitude and speed, fuel and climb/descent planning, glidepath, and sunrise, sunset, and night times. Holding guidance includes three entry types with a north-up diagram; fuel-switch and hold-leg timers are described as sending iOS notifications while the screen is locked. The page says the app runs offline, identifies sources on reference pages, and keeps squawk codes, comms-failure procedures, light signals, and interception references free.
