The FG-4000 features an 866MHz Pentium processor and a display that will adjust for the brightest sunlight or the darkest night without loss of readability or night vision.

Although this installation does not constitute approval for paperless operation, it is the first step toward such approval. The customer must coordinate paperless operational approval through the local FSDO. The installation of this system does not guarantee that paperless operation will be approved.
A network STC business case has been approved for the Lear 31, 35, 36, 45, 55, and 60.
The conformity aircraft for each STC must undergo certification flight-testing which will increase the required downtime for this installation. Additional lead-time for certification will also be required for the conformity aircraft.
