ASA E6B Metal Flight Computer

What buyers think

Buyer-review evidence is strongly skewed toward satisfaction, with themes centered on durability, ease of reading, and training usefulness. Multiple pilots and students describe the metal build as a step up from paper/cardboard versions, with improved resistance to damage from everyday bag life. Users also mention that the markings are clear enough to follow during instruction and that it functions as a reliable backup after years of use with older E6B units. Where sentiment is present, it tends to frame the E6B as both a practical learning tool and a “hands-on” calculator-style instrument, but the amount of feedback specifically detailing precision, long-term mechanical wear, or day-to-day usability is limited.

What this E6B can calculate

This is a manual flight computer built around two working areas: a circular “calculator” side and a “wind” side.

Calculator side (slide rule style)

The calculator side is intended for common arithmetic and flight-planning computations, including multiplication, division, and unit conversion. It also uses printed scales to work through values related to time, speed, distance, rate, and fuel consumption, plus altitude, airspeed, air temperature, and pressure pattern calculations.

Wind side (graphic wind and navigation problem solving)

The wind side uses a graphic method for solving and displaying wind-related answers. It supports simpler addition and subtraction-style steps, then expands into typical E6B wind triangle and navigation tasks such as:

• True wind and winds in flight style calculations
• True course and ground speed
• True heading and true airspeed
• Off-course correction calculations

There is also a matte finish on the wind side meant for pencil marking during use, with an easy wipe-clean approach between problems.

Key specs that affect fit

• Form factor: circular flight computer, about 6 inches in diameter (listed as 6"L x 6"W).
• Build: metal enclosure, designed for durability versus paper versions.
• Size and weight: 0.64 lb, making it practical as a training desk tool or a bag backup.
• Calculator type: flight computer using slide-rule style scales and procedures.
• Display: VFD is listed as “screen size” 6 inches, which suggests an integrated display component alongside the scale-based calculation approach.

Pros and cons for different kinds of pilots

Best for

• Flight students and instructors who want a manual learning tool that helps internalize planning and wind concepts.
• Pilots building a backup kit for quick reference when you do not want to rely on a phone or tablet.
• Anyone who prefers durable, physical instruments over more fragile paper/cardboard options.

Who should avoid it

• Busy pilots looking for instant results without a learning curve, or those who only want tap-and-go calculations.
• People who strongly prefer app-based workflows and do not want to carry a dedicated manual tool.

Comparison guidance (how to choose instead of “either/or”)

Without specific competitor models named here, the decision usually comes down to what kind of assistance you want for flight planning:

• If durability matters and you want bag-friendly backup: a metal E6B design is the clear fit versus paper/cardboard versions.
• If your priority is speed and minimal setup: you may prefer a digital planning app, since the E6B requires manual alignment and steps.
• If you are training or studying wind fundamentals: an E6B’s wind-side graphic workflow can be easier to learn from than purely automated outputs.

The ASA E6B Metal Flight Computer is a solid choice when you value the physical process and want a durable instrument for planning and practicing computations.

Verdict

The ASA E6B Metal Flight Computer is a practical, durable circular flight computer that supports a wide range of manual planning and wind-navigation calculations. Buyer feedback most consistently supports its build quality, readable markings, and usefulness in training and as a backup tool. It is worth buying if you want a hands-on manual reference you can rely on, just remember that learning to use an E6B takes some time if you are coming from modern digital tools.

FAQ

What is the ASA E6B metal flight computer used for?

It is used for manual flight calculations, including basic arithmetic and flight planning problems on the calculator side, plus wind and navigation-related computations on the wind side.

Is this better than a paper or cardboard E6B?

The metal build is intended to be more durable for everyday carry in a flight bag. Many buyers choose it specifically as a step up from more fragile paper/cardboard versions.

Does it have a learning curve?

Yes. Because it uses slide-rule style procedures and graphic wind problem solving, it generally takes some practice to use efficiently, especially if you are used to apps.

Can I mark the wind side while solving problems?

Yes. The wind-side matte finish is designed to be marked with a pencil during use and wiped clean for the next problem.

Is it a good backup for experienced pilots?

It can be, particularly if you want a reliable manual reference for common planning and wind computations when you do not want to depend on a phone or tablet.
