Page 18: First Flight With G3/G4
G SERIES PILOT’S GUIDE First Flight With The G3-4 Now that the day is finally here for you to fire up your new G3-4 and take it for a flight you are probably eager to explore all the new functions. Before you take that first flight a few minutes should be invested to check the installation of the instru- ment. -
Page 19: Using G3-4 On The Ground
G SERIES PILOT’S GUIDE After you have returned to the airport and shut down after your first G3-4 test flight, we recommend you remove the SD Card and examine the data log using your favorite spreadsheet program. If you didn’t get a chance to set your EGT bar heights as discussed earlier, you will get a good idea where it should be set for next time by looking at the EGT columns. -
Page 20: Using G3-4 On Take-Off
G SERIES PILOT’S GUIDE During the mixture check, a uniform rise of EGT indications for all cylinders will confirm that the mixture control is functioning correctly. The amount of temperature rise will depend on the degree of mixture control movement. -
Page 21: Leaning For Take-Off
G SERIES PILOT’S GUIDE A New Approach to Engine Management The G3-4 is a sophisticated tool for engine management. Its microprocessor performs many tasks that used to be handled by the pilot. One of the basic functions performed by the G3-4 is monitoring exhaust gas temperatures for all cylinders with one degree resolution. -
Page 22: Configuration Screens
G SERIES PILOT’S GUIDE G3 and G4 Configuration Screens There are SIX configuration screens. The Registration Config, General Information, Engine Configuration, Set Time/Date, K-Factor Initialation and MISC Configuration screens are accessible only on the ground. Setup mode accessed by rebooting instrument with top button held in. -
Page 23: G3-4 Operating Procedure
G SERIES PILOT’S GUIDE G3-4 Operating Procedure Since the introduction of the Graphic Engine Monitor in the early 80’s a new leaning procedure has been developed. Once frowned upon, leaning past peak to operate on the lean side in cruise is now widely used to save fuel. -

Page 25: Setting The Peak Detect Threshold
G SERIES PILOT’S GUIDE Setting The Peak Detect Threshold The user may set the peak detect threshold anywhere from 0-99 degrees by pushing the lower button twice and then turn- ing the knob to set the desired number. When complete a short push of the bottom button will clear the threshold setting message. -
Page 26: Leaning In Cruise
G SERIES PILOT’S GUIDE Leaning in Cruise The G3-4 is ready for leaning without any user action. If necessary press and hold the bottom button to clear any peak temperature boxes. As the pilot leans the engine the bars will rise then fall leaving a peak temperature box behind. This box will show the distance in degrees from peak and whether the mixture is rich or lean of peak. -
Page 27: Importance Of Measuring Turbine Inlet Temperature
G SERIES PILOT’S GUIDE There are certain times when you should not lean to peak or even attempt to find peak. In full power climb or any time the engine is operating at power settings in excess of 75%, leaning to peak could result in detonation and serious engine dam- age. -
Page 28: Special Considerations For Twins
G SERIES PILOT’S GUIDE Another observable characteristic is that the required fuel flow is dependent on altitude under conditions of constant rpm and manifold pressure. It may seem reasonable that the optimum mixture for a given power setting should remain constant. -
Page 29: G3-4 Monitoring
G SERIES PILOT’S GUIDE G3-4 MONITORING OAT is displayed as straight numbers when temperature is positive. A negative sign is shown for temperatures below zero. OAT is displayed in Fahrenheit. The Bar-Graph Display Screen The Exhaust Gas Temperature is displayed in white bar graph form and is interpreted much like a conventional mercury thermometer. -

Page 31: Periodic Temperature Variation Screen
G SERIES PILOT’S GUIDE PERIODIC TEMPERATURE Variation Screen Variation degrees Time in minutes Periodic Temperature Variation is a new form of engine analysis. Some valve related engine faults produce a slow periodic variation in EGT. The oscillation rate is on the order of one cycle every minute or two. - Page 32 G SERIES PILOT’S GUIDE If you take a step back from the EGT/CHT idea to explore engine monitoring in general, you discover that at least half the engine monitoring solution is missing. EGT analysis reveals combustion phenomenon but simply ignores mechanical prob- lems.
