Cessna 150 with new indicators

Many years ago we established cooperation with the Polish Aero Club. We perform periodic checking of flight instruments in the Polish Aero Club Aircraft fleet. In the first quarter of this year, we made a simple but sufficient upgrade of 5 Cessna 150 aircraft of the Polish Aero Club. In several of them, we had already replaced the transceivers with modern ones with 8,33 kHz separation and carried out their periodic inspection.

This time the airplanes have been retrofitted with a new pilot parameter indication system - the Garmin G5 electronic indicator in a configuration with the GMU 11 magnetometer.

The Electronic Flight Data Indicator replaces traditional electromechanical flight instruments and fits into a typical 3.5- inch instrument hole, so no panel rework is required. The G5 can be configured as a standalone basic flight parameter display with optional autopilot mode. Offering a bright 3.5-inch sunlight-readable liquid crystal display (LCD) with built-in GPS, the G5 displays own position, ground track, altitude, flight speed, ground speed, vertical speed, slip and skid angle, and includes a dedicated HSI display page.

Additionally, the electronic instrument can be used as part of the highly efficient, autonomous GFC 500 autopilot, in conjunction with compatible autopilot mode and autopilot servos. In conjunction with the GMU 11magnetometer and the GAD 29 interface, and with the NAV / COMM and GPS data source selected, the G5 can serve as the primary magnetic heading reference instrument. In addition, the G5 can serve as an attitude indicator - both the main and the backup.

The G5 has received FAA and EASA approvals for installation in single and twin engine FAR Part 23 or EASA CS-23 certified aircraft with a take-off weight less than 6.000 lb (approximately 2,700 kg). In case of the aforementioned five Polish Aero Club planes, the quick upgrade consisted in disassembling the current attitude indicator and replacing it with the G5 indicator and adjusting the plastic cover of the instrument panel to the rectangular shape of the new indicator.

In addition to the modern attitude indicator, pilots now have in one place additional information about speed, flight altitude, turn indications and magnetic heading data. Everything is presented in the same format found on airplanes with large PFD displays.
