Restore Purchase

One purchase unlocks the app for good on your Apple ID. On a new device: tab Calculator, gear, Restore Purchase. The same button is on the purchase sheet. You don't need an account.

What the app does

• A flight calculator: wind triangle, crosswind, true airspeed, density and pressure altitude, time, speed, distance, fuel, units.
• A simulated E6B, both sides, drawn from the formulas.
• Practice problems, generated and graded, solved in the app or on your own E6B.
• Weight and balance on a fictional example, or on your own aircraft with the purchase. You enter the values from your manual.

What it doesn't do

• It isn't an instrument for use in flight. It's a training and planning aid only.
• It doesn't replace your instructor or your aircraft's manual, and it includes no aircraft data.
• It makes no promise about any exam. It names common slips it can recognize, not every mistake.
• It has no account, no server and no subscription, and it works offline.
