Why does the GEM use a bar graph for EGT and CHT?
Ergonomics are an important part of instrument design. Insight pioneered the use of the gas-plasma bar graph for displaying EGT and CHT because of it’s ideal suitability for this application. The graphical format displays all the data simultaneously in a way that’s easy for the pilot to read and understand. Remember that Insight’s 25 degree per bar resolution acts as a data filter to display only significant changes in temperature.
