Garmin GTN 750Xi: Simpler Radar Ops

There’s a process for properly using ship’s weather radar, but Garmin streamlines the chore with smart logic built into the GTN 750Xi navigator.

The GWX 8000 has a 16-color graphics interface for the GTN 750Xi navigator and GTN TXi aftermarket displays.

There’s a reason why Garmin and others dedicate entire pilot training courses to ship-based weather radar operation. I completed a couple of these courses and learned that if you’re new to using radar to strategically work your way around weather, you’ll want a solid understanding of control logic and reading the display graphics before making a run at serious weather.

While not a substitution for weather radar training, Garmin has automated the chore of tactically using its GWX 8000 StormOptix radar and GTN 750Xi/725Xi aftermarket navigator interface, borrowing a feature set and logic used in its OEM integrated flight decks. This includes automatic control over the radar’s tilt and gain commands.
