## What is E6B Flight Computer Slide Rule?

Check your E6B reading. Solve a problem on your own E6B, type what you read, and the app tells you if it's good. When your numbers point to a slip, it names it, then walks the steps on a simulated E6B.

FREE, WITH NO LIMIT
• Flight calculator: wind triangle (heading, track, or the wind itself), crosswind, true airspeed, density and pressure altitude, time, speed, distance, fuel, units. Negative temperatures, US and metric. Each computed result opens its formula and source; unit factors are one tap away.
• The E6B, both sides, drawn from the formulas. Rotate, slide, zoom.

ALSO FREE
• Over 50 practice problems, generated and graded: a lifetime count per type.
• Weight and balance on a fictional example: loading, CG, envelope.

ONE PURCHASE ($9.99 in the US)
• Unlimited problems, graded on your E6B or in the app.
• Your own aircraft, saved. You enter the values from your manual.

One purchase. No subscription. No account. Works offline.

WHAT IT ISN'T
The phone stays out of the test room: you use your E6B or a calculator there, and this app gets you ready. It makes no promise about any exam. It names common slips it can recognize, not every mistake.

Not an instrument for use in flight. Training and planning aid only. Doesn't replace your instructor or your aircraft's manual. No aircraft data is included.

Not affiliated with or endorsed by the FAA or NWS.
