Replace your Tachometer with EI’s CGR-30P, and bring glass panel technology to your panel today, without breaking the bank. The CGR-30P is a TSO’d, STC’d Primary Replacement engine instrument. What can it replace? The answer: most of the aircraft’s primary engine functions.
Overview: The CGR-30P comes standard with a state-of-the-art, full-color bar graph which assists with ROP/LOP leaning. Additionally, the bar graph has both “normalized” and digital readout screens. No other bar graph in the industry comes close to providing the number of options the CGR-30P offers.
ROP Mode: The Rich-of-Peak mode on the CGR-30P informs the pilot when the ﬁrst cylinder peaks, as well as how many degrees below peak the engine is operating.
LOP Mode: For Lean-of-Peak Operations, the CGR-30P informs the pilot as each cylinder peaks, at what temp each peaks, and how far from peak each is. For quick reference, every cylinder’s peak information is constantly displayed and “tattletale bars” are shown above each cylinder, indicating where each cylinder peaked the last time the engine was leaned.
Normalized Mode: The Bar Graph can easily be “Normalized,” creating a baseline from which to monitor in- ﬂight engine temperature changes. When Normalized, all of the bars start off at the same height. If any cylinder’s column is not the same height as the others, than that cylinder’s Exhaust Gas Temperature has changed in relation to the other cylinders. These changes can be critical indicators to problems occurring within your engine.
Peak Markers: While other monitors don’t maintain your engine’s leaning history, The CGR-30P’s Bar Graph keeps track of exactly where the cylinders peaked during each leaning process. When leaning, the CGR-30P displays a peak marker indicating where each cylinder peaked during the last leaning process, providing visual assistance to pilots.
