The Navtronic Explorer was developed in the year 1983 by Specialized Electronics Corporation (SEC) together with the Navigator. Compared with calculator based Flight Computers like the Jeppesen Sanderson prostar of the same time slot this Explorer gives you much more features and continues the approach of powerful "Navigation only" products started with the Navtronic 1701 series and the Heathkit OCW-1401.

The basic aviation program of the Navigator and Explorer include:

True Airspeed and Calibrated Airspeed calculation
Density Altidude conversion
Time to Climb, Distance to Climb and Rate of Climb calculation
Ground Speed calculation
Fuel requirement and Consumption Rate calculation
Weight and Balance calculations
Estimated Ground Speed and Heading calculation

The Explorer added:

Rhumb Line calculations
Timer and Clock operations
RNAV calculations

Both the Navigator and Explorer were approved for use in taking Federal Aviation Administration (FA) tests.

The high building quality of the original Explorer was later reduced, view a 1987'er model here.
