Application Guide and the Approved Parts Matrix referenced in the Supplemental Type
Certificate identifies the appropriate LASAR
®
system configuration for each certified engine or airframe
application. For non-certified installations, the maximum engine operating temperature must be
determined by following the procedures outlined in Section 2. If the observed maximum engine operat-
ing temperature is within 50°F of the maximum limit specified by the engine manufacturer, LASAR
®
ignition equipped with CHT control is recommended.
