Flight computers

Electronic flight computers (or aviation / navigation calculators) are used mainly during flight planning. They help calculate fuel consumption, wind correction, time and route among others. During flight they can be used to calculate ground speed. Most flight computers are electronic counter parts of the ubiquitous E-6B circular slide rule.

With the advent of more sophisticated GPS enabled flight computers, the simple E6B variants are less popular these days. That said, they are still used by many students and even airline pilots.

New Tamaya NC-2 that has never been out of the box.
Father bought it while building a 42' sailboat. He never finished the boat. I came across this calculator while moving his office. Has never even had a batteries installed.
Looking to sell.

The Tamaya NC-2 has a 10 digit vacuum florescence display. Digits are 5mm high.
It was manufactured by Sharp using a Hitachi chip set.
The Tamaya company specializes in manufacturing marine navigation instruments (such as sextants).
The NC-2 nameplate reads: "Astro-Navigation Calculator" (meaning "astronomical navigation").
While it could be used for aircraft navigation, it is not properly called a "flight computer" in my opinion.

My NC-2 is serial number 60000146. It was purchased by my father in 1976 who used it navigate his sailboat from San Diego, California to Maui, Hawaii in 1977.

Tamaya is for me one of the most convinient and powerfull tool for navigation. I've been using since then and it is so accurate that distances are computed as WGS '84, which chart before are not yet in such form. Many thanks to the Japanese seamen who contributed such machine.

Hello Francois,

Glad you like the site :)
To obtain a Tamaya I can only point to the obvious places like ebay and others. I don't have any navigational calculators for sale at the moment.

Good luck on your search!

P.S.: I removed your address from the comment, no need for the whole world to see that.
