The navtronic 1701t is based on the earlier navtronic 16 but added a physical protection to the 14 LED-indicators on the keyboard panel.

The 1701t is one of four very similar flight computers:

• navtronic 1701: Basic navigation calculator
• navtronic 1701t: Added TIMER function (START, STOP keys)
• navtronic 1701r: RNAV functions (R1, R2, D1, D2 LED-indicators)
• navtronic 1701tr: TIMER and RNAV functions

If we trace back in the history of electronic flight computers we discover: The Commodore N-60, the Heathkit OCW-1401 and the navtronic 16 resp. navtronic 1701 models. All were introduced around the year 1978, two years before the Jeppesen Sanderson avstar based on a Texas Instruments TI-35 appeared.

In 1983 with the Navigator and Explorer enhanced flight computers were introduced.

There are some rumors that the "1701 series" got it designations as a nod to Star Trek, the U.S.S. Enterprise is #1701. The 1701 itself comes from "FAA registry of a Waco biplane, owned by TOS chief designer Matt Jefferies".
