ASA Colour E6B Flight Computer

ASA Colour E6B Flight Computer

Bring a clearer view to your flight-planning calculations with the ASA Colour E6B Flight Computer. This manual, slide-rule-style flight computer combines solid aluminium construction with colour-coded scales, making it easier to distinguish the information you need on both the circular calculator and wind sides.

Whether you are working through a flight-planning exercise or practising your E6B technique, the colour layout provides helpful visual reference points as you move between calculations. It is a practical option for pilots and student pilots who prefer a hands-on approach to working with time, distance, rates and wind correction.

Colour-coded scales for easier reading

On the circular calculator side, black identifies the rate arrow and the units to be calculated. Red highlights weight and volume, while blue identifies the distance, time and temperature scales. Separating these groups by colour helps you locate the relevant scale without relying on a single-colour layout.

The wind side also uses colour to distinguish directional references. Blue identifies west or a right wind correction angle, while red identifies east or a left wind correction angle. These visual cues support your use of the wind side as you practise and work through calculations.

A hands-on tool for flight planning and practice

The ASA Colour E6B retains the traditional manual format, with no batteries or charging required. Keep it alongside your planning notes when working through an exercise, then use the included instruction booklet to familiarise yourself with its scales and operation. For student pilots, it offers a way to practise the process rather than simply entering values into an electronic calculator.

Frequently asked questions

Is this a manual or electronic flight computer?

This is a manual E6B flight computer. It uses a slide-rule-style circular calculator and a wind side rather than an electronic display, so it does not require batteries or charging.

What is the benefit of the colour-coded scales?

The colours help distinguish different scales and references. On the circular side, black is used for the rate arrow and calculation units, red for weight and volume, and blue for distance, time and temperature. The wind side uses blue for west or right wind correction angles and red for east or left wind correction angles.

What is the flight computer made from?

The ASA Colour E6B has solid aluminium construction.

How large is it?

It measures approximately 248 × 127 mm, equivalent to 9¾ × 5 inches. Check these dimensions against your flight bag or planning kit if space is important.

Does it come with a case and instructions?

Yes. A vinyl case and an instruction booklet are included.

Can I use it to practise flight-planning calculations?

Yes. Its manual format lends itself to hands-on practice with the calculator and wind sides. Start with the included instruction booklet and follow your instructor's preferred methods when using it for training.
