Northrop Grumman says it’s successfully flight tested a jam-proof navigation system to replace the current gear on military aircraft. Embedded Global Positioning System (GPS) / Inertial Navigation System (INS) Modernization, known as EGI-M, was installed on a Cessna Citation and put through its paces in May.

Remember when you were a student pilot prepping for the cross-country flights with a sectional chart, using your plotter to calculate the true course to the destination?

Technologies develop, sometimes slowly over time, with the kind of sloth that makes you wake up one day, see an evolved landscape, and question your strongly held beliefs. Such as: For any airplane you’d consider flying in instrument conditions, at least a modicum of redundancy is required. We used to want fully distributed systems to […]

Garmin introduced its new GTN 650Xi and GTN 750Xi all-in-one touchscreen navigators on Wednesday. The GTN 650Xi and 750Xi are Garmin’s fourth-generation GPS/Nav/Comms and feature faster map rendering and smoother panning than their predecessors along with an ultra-high-resolution display and wide viewing angle.

With another sign that the avionics retrofit market is getting more competitive, Avidyne is targeting vintage light jets with its Atlas flight management system.
