Learjet 35A – Universal UNS-1Lw FMS Upgrade

Our Part 21J have just completed a Flight Management System upgrade for a German customer and their Learjet 35A.

Project Summary

The design introduces a Universal UNS-1Lw and electronic Sandel SN4500/SN3500 Primary Navigation Displays which enables the aircraft to fly operations requiring Performance Based Navigation (PBN) specifications RNP 1 & RNP 2. This EASA Major Change is a very much welcomed upgrade to the ageing, but still impressive 35A.
