Think of it as having a conversation at the same time with two or more people standing on either side of you. As long as you can clearly hear the sounds separately on different sides, interpreting and understanding what’s being said becomes much easier.
If that wasn’t enough, the GMA 350 also features voice recognition technology for hands-free communication switching and control. For example, simply press the “push to command” switch and say “Comm One” or “Comm Two” and the unit switches automatically between radios. Best of all, the voice technology
really works. Helicopter pilots, especially, love the hands-free features of the GMA 350. Pilot and co-pilot can also select independent frequencies on which to broadcast, while audio sources for different seating positions can be controlled independently, allowing your passengers to listen to music while you talk on the radio.
>>> JPI EDM-730/830 Digital Engine Monitor
LIST PRICE (EDM 730-6C): $2,888
Have you ever wished you could upgrade to digital engine gauges without tearing up your panel or breaking the bank? J.P. Instruments’ engine data management systems allow aircraft owners to do just that, by sliding the EDM unit into a standard 3.1-inch panel hole as a quick and easy way of consolidating an array of engine-related data on a single display.
The EDM-730/830 is a full-color evolution of JPI’s earlier 700/800-series engine monitors, with an LCD display that can be rotated 90 degrees for installation in landscape or portrait orientation, even in the tightest of panels. The unit provides digital readout of an array of engine parameters, from EGT and CHT values to rpm and manifold pressure, and more. New features of the color models include default settings allowing use of lean-of-peak or rich-of-peak modes at start-up, and manual cycling through all parameters. The major benefit of the digital gauge, says JPI, is more precise leaning resulting in better fuel economy, reduced maintenance costs and longer engine life.
The EDM unit constantly redline-checks all engine parameters, providing readouts at the top of the display depicting rpm and manifold pressure both graphically and digitally. The EGT and CHT bar graph presentations can be fine-tuned by pressing the Leanfind button on the unit’s face. A white bar graph shows CHT values while a blue bar graph shows EGT. Warnings for any parameters outside the normal range will flash red. The unit can also display oil temperature, oil pressure, battery voltage, OAT, the difference between the hottest and coolest cylinders and other data, such as optional fuel-flow information.
