EGT

Exhaust gas temperature (EGT)
Tags: FAA Pilot's Handbook
Exhaust gas temperature (EGT). The temperature of the exhaust gases as they leave the cylinders of a reciprocating engine or the turbine section of a turbine engine.

EGT - exhaust gas temperature (gauge). A device which provides a cockpit readout of the exhaust gas temperature of an aircraft's (piston) engine(s), enabling the pilot to lean the mixture for maximum fuel efficiency.

EGT: Exhaust Gas Temperature. One of the flight deck's engine gauges.
EICAS: Engine Indication and Crew Alerting System. A CRT display indicating engine performance and alerts.
ELB: Emergency Locator Beacon. See ELT (below).

Previously this panel position held an EGT. Below and to the left of the clock you can see a red light. This is a warning light that the clutch is not engaged. The clutch on the Enstrom is mechanical and takes quite a strong pull to engage.

By leaning, the engine runs more fuel efficient and with higher temperatures, the only requirement is that you keep an eye on the EGT and or fuel flow gauges. You do not want to burn out the exhaust valves prematurely.

EFIS panels integrate all kinds of instrumentation into one easy-scan display: flight instruments (airspeed and altitude, etc.), engine readouts (rpm, CHT and EGT, etc.), magnetic compass, slip/skid ball and even GPS, clock/timer, ...

Early in the takeoff roll, you should glance at the gauges (RPM, manifold pressure, fuel flow, and EGT) to make sure the readings are normal — and that both engines are the same.
