E6-B Metal Flight Computer – Large
$58.95
The ASA metal E6-B: the manual flight computer most Canadian students learn on. Solid aluminum, with the wind side and calculator side printed in clear, readable lettering that survives a full licence and beyond.
- Solid aluminum construction, not cardboard
- Wind component grid and crosswind correction chart
- Time, speed, distance, altitude, true airspeed, density altitude, conversions
- Nautical and statute scales
- Allowed in Transport Canada written exams
Used by students in our PPL and CPL Ground School. A step up from the basic computer included in the Ground School Kit.
Description
The ASA Metal E6-B Flight Computer
The E6-B is the circular slide rule pilots have used for flight planning since the 1940s, and it is still the tool most Canadian students learn on. This is ASA’s aluminum version: the one that holds up to four years in a flight bag instead of softening at the corners after one term.
Two sides, no batteries. The calculator side handles the arithmetic of flight planning. The wind side solves the triangle graphically, so you see what the wind is doing to your aeroplane rather than reading a number off a screen. That is the reason instructors still teach it, and the reason it keeps showing up in cockpits long after the licence is framed.
Calculator side
- Time, speed, and distance
- Fuel consumption and endurance
- True airspeed and density altitude
- Altitude and temperature corrections
- Unit conversions, nautical and statute scales
Wind side
- Wind component grid
- Crosswind correction chart
- Wind correction angle and ground speed
- True heading from true course
- Off-course correction
Allowed in your Transport Canada written exam
A manual flight computer is permitted in Transport Canada written knowledge exams, which is the practical reason to own one even if you flight-plan on an app. Learn it on the ground, before exam day is the first time you reach for it. Transport Canada’s TP 12880 study and reference guide sets out what you need to know.
Metal, paper, or electronic?
We sell all three because they suit different students. Here is the honest comparison.
| Option | Price | Best for |
|---|---|---|
| Metal E6-B (this one) |
$58.95 | Students who want one that lasts the whole licence and beyond. Aluminum body, crisp lettering, the standard most instructors teach from. |
| Paper E6-B | $20.95 | The budget option. Same calculations on heavyweight fiberboard. Fine for ground school, but it wears at the edges with daily use. |
| CX-3 electronic | $184.95 new $154.95 open box |
Faster under exam time pressure and useful through commercial training. Many pilots own both: the E6-B to understand it, the CX-3 for speed. |

Using it in your training
Most students meet the E6-B during the navigation portion of ground school and then live with it through cross-country planning. Our Private Pilot Ground School and Commercial Pilot Ground School both teach the calculations this computer performs, so you are not left working out the wind side from a diagram in a book.
A basic flight computer comes with the Ground School Kit. This metal version is the common upgrade for students who would rather buy once. Pair it with a Douglas protractor and a kneeboard and your navigation kit is complete.
A colour version is available on request. Contact us and we will let you know what is in stock.
E6-B Flight Computer FAQ
What is an E6-B flight computer used for?
Flight planning calculations: time, speed and distance, fuel burn, true airspeed, density altitude, unit conversions, and the wind triangle. The wind side gives you wind correction angle and ground speed graphically.
Can I use an E6-B in a Transport Canada written exam?
Yes. A manual flight computer is permitted in Transport Canada written knowledge exams. Practice with it well before exam day rather than learning it under time pressure.
Metal or paper E6-B, which should I buy?
Both perform the same calculations. The metal version is aluminum and lasts through a full licence and beyond. The paper version at $20.95 is the cheaper way in, but it wears with daily use.
Do I still need an E6-B if I use an electronic flight computer?
Most instructors want you to understand the manual one first, because it shows you how the wind triangle actually works. Plenty of pilots carry the CX-3 for speed and keep the E6-B as the backup that never needs a battery.
What size is it?
This is the large model, the standard full-size E6-B that instructors teach from. The larger scales are easier to read and more precise than the pocket version.
Do you ship across Canada?
Yes, we ship Canada-wide from Ontario. See our pilot shop for everything else you need for training.
