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.
