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 three very similar flight computers:
|
• navtronic
1701: Basic navigation calculator • navtronic 1701t: Added timer function (START, STOP keys) • navtronic 1701tr: RNAV functions (R1, R2, D1, D2 LED-indicators) |
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 1701t 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".
