## What is Rotate E6B Flight Computer?

An E6B that shows its work.

Rotate E6B Flight Computer does every calculation a mechanical E6B does — and then opens the result to show you the formula and each step with the numbers you entered, so you can check it instead of trusting it. That is the part a plastic disc and most apps leave out, and it is the part you need when you are learning.

WHAT IT CALCULATES
• Wind triangle: ground speed, wind correction angle, true heading
• Unknown wind, from heading, course and the two speeds
• True and magnetic heading, with variation and deviation
• Time, speed and distance — to the second, not rounded to the minute
• Fuel burn, endurance and required fuel
• Crosswind and headwind components
• Pressure altitude, density altitude and true altitude
• True airspeed from indicated
• Rate of descent and top of descent
• Cloud base and freezing level
• Weight and balance: moments, centre of gravity and an envelope chart that tells you in or out
• Unit conversions, including negative temperatures

BUILT FOR THE EXAM AND THE COCKPIT
Wind, fuel and density-altitude problems appear on every FAA written. The calculators use the exact trigonometric formulas, so the answers do not drift the way a dial reading does — and the step-by-step breakdown is how you learn to produce the answer yourself when the figure is on the exam sheet.

Everything runs on the device. No signal, no account, no sign-in. Nothing you type is ever transmitted.

DESIGNED TO BE USED IN FLIGHT
• A keypad built for the job: large keys, decimals and negatives, and no hunting for a tiny "=" — results update as you type
• On iPad the keypad sits beside the fields instead of covering them
• Light and dark, readable in a bright cockpit
• History and favourites, so a cross-country you ran last week is one tap away
• Your own aircraft: enter the arms, moments and envelope from your POH and save the profile

WHAT IT COSTS
Five calculators are included at no charge, permanently. The rest unlock with a single one-time purchase — not a subscription, nothing to cancel, and it restores on every device signed in to your Apple ID.

Built by Rotate, who make the FAA exam prep at rotatepilot.com.

Questions, or an answer you think is wrong? hello@rotatepilot.com — send the numbers you entered and the answer you expected.

Unlocking the full version is a one-time purchase, charged once to your Apple ID. It is not a subscription: nothing renews and there is nothing to cancel.
