The navtronic 16 flight computer was developed by Specialized Electronics Corporation (SEC) and introduced 14 LED-indicators to prompt the individual entry values. The navtronic 16 was soon replaced with the navtronic 1701 resp. 1701t adding a protection to the indicators on the keyboard panel.

If we trace back in the history of electronic flight computers we discover: The Commodore N-60, the Heathkit OCW-1401 and this navtronic 16. All were introduced around the year 1978, two years before the Jeppesen Sanderson avstar based on a Texas Instruments TI-35 appeared.

The navtronic 16 uses a chip set manufactured by National Semiconductor. The empty space on the printed circuit board is used with the later Navtronic 1701t.
