1.2.2.5 Engine Indication System (EIS)
The GI 275 provides EIS display for four- and six-cylinder reciprocating engines. EIS does not include
turbine engines. An EIS installation consists of one GEA 110 or GEA 24 per engine and one GI 275 per
engine.
The EIS display can drive caution and warning lights that may be required for installation when the
indicator is not installed in the primary field-of-view.
The EIS display collects powerplant data and utilizes an automatic monitoring system that interprets and
reports the data to the pilot in the form of an alert. The crew can acknowledge the alert, which prompts the
indicator to display page one, which contains the data parameter in question. This reduces the amount of
information displayed at a given time to the crew, allowing the EIS indicator to work for the pilot by
monitoring engine data and notifying the crew with an alert.
The EIS has the capability to configure up to five pages. Each configured parameter with alerting markings
on page one is tied to an alert that will be displayed across the bottom of the screen when an exceedance
occurs. Additionally, critical performance data is displayed on every page: fuel quantity, RPM, and if
applicable, manifold pressure.
GI 275 with EIS offers three aircraft timers: Flight Hours, Hobbs Timer, and Tach Timer. Flight Hours
accrue in-air, as the status is derived from weight-on-wheels, GPS speed, or engine RPM. The Hobbs
Timer is activated by engine oil pressure (was Engine Time in software v2.11 or earlier). Tach Time
(software v2.20 or later) accrues relative to engine cruise RPM.
