August 2014- The new Insight Avionics GX-MFT offers three engine function displays in one easy-to-read, three-inch LED instrument. The instrument shows manifold pressure, fuel flow and a tachometer display, plus in-depth electrical system analysis.
Insight expects approval of its STC application by both Transport Canada and the FAA very soon.
The GX will be certified as a primary instrument so that it can replace two instruments (manifold pressure and tachometer) and free up valuable panel space for an Insight G4 engine monitor. Even during an electrical failure the tachometer display will continue to operate indefinitely with no battery backup required. (Emergency power is supplied using energy harvesting. —Ed.)
The manifold pressure and fuel flow information are displayed as vertical lines with a digital display below the vertical analog readout. The tachometer value is shown as a circular analog plus a digital tachometer display.
During mag checks the RPM digital display momentarily displays mag drop and then returns to its normal RPM reading. Insight builds in red, green or display markings to your engine’s specifications and limitations. The integral hour meter is capable to a factory-preset value for your aircraft’s current total time.
The key to the GX-MFT’s functionality is the ability to go beyond displaying simple electrical instruments and thoroughly detect and analyze electrical system faults.
The bottom portion of the LED can display measurements to monitor battery analysis, alternator diode health, and over-/under-charging. Circuit integrity analysis can help spot difficult-to-diagnose poor or intermittent connections. All of these parameters are logged to the integrated data logger memory card and can be downloaded for further analysis.
The reliability of an electronic tachometer is, in my opinion, superior to any mechanical tachometer with its associated cable failures.
