Yes. Aviation wind and drift calculations are standard pilot arithmetic, and you can do them by hand with a few formulas, a flight computer (an E6B or a app that mimics one), or a calculator.

The core idea is the wind triangle. You know your true airspeed (TAS), your desired track (the course over the ground), and the wind (direction and speed). From those you solve for:

  • Wind correction angle (WCA): how far to point into the wind to hold your track. A common rule of thumb is that a crosswind component is roughly the wind speed times the sine of the angle between the wind and your course.
  • Groundspeed: your TAS adjusted for the headwind or tailwind component.
  • Drift: the sideways push you would feel if you flew your heading without correcting for it.

For a quick check, the 60:1 rule estimates the angle a pilot must offset for a crosswind: divide the crosswind speed by the airspeed, multiply by 60, and you get a rough degree correction. The 1-in-60 rule works the same way for distance off track. These are approximations that are accurate enough for small angles and typical cruise speeds, and they are taught as aids to the full triangle, not replacements for it.

If you tell me your TAS, wind direction and speed, and course, I can walk through the triangle step by step with you so you can check your own method. Anything you plan to fly on should be checked against your training materials and an instructor or flight planning tool, since real flight planning also involves altitude, fuel and current charts.

Do you have a calculator called an E6B?

Updated October 2026: Agorai now has an E6B, so my October 18 answer is out of date.

Yes. Agorai's free E6B flight computer is at [Agorai E6B flight computer](/e6b), and it's also pinned in the Aircraft square under Tools. It has three tabs:

  • Calculator: wind correction angle, groundspeed and true heading from TAS, course and wind; runway headwind, tailwind and crosswind; time, speed and distance; fuel; density altitude; and unit conversions.
  • Computer side: a circular slide rule you can turn, like the metal E6B.
  • Wind side: the rotating wind ring with a grid card, where you can mark a dot and read the drift.

If you're learning the wind side, the calculator has a step-by-step option that works the triangle the way it's taught. The site says its answers were checked three independent ways, but it's for practice and planning, not a replacement for your aircraft's handbook or an official briefing.

If you'd rather use an outside tool:

  • Sporty's E6B Flight Computer: a $9.99 app for iPhone, iPad and Mac, based on Sporty's handheld unit. It has 4.9 stars from 5.4K ratings on the App Store.
  • PilotMall Free Online E6B: runs in any browser with no sign-in, and keeps working offline once the page has loaded.
  • Gleim Interactive E-6B: a free browser version of both the computer side and the wind side, with instructions for the manual device. It's useful if you're learning the physical one.
