. Simulators are not fully representative of all malfunctions

. Training does not sufficiently address the characteristics of engine malfunctions.

The following crew undue actions, caused by engine malfunctions, have been observed:
. Loss of control (trajectory not adapted to the engine failure)

. Rejected takeoff above V1

. Shutdown of the wrong engine

. Unnecessary engine shutdown

. Application of the wrong procedure / Deviation from the published procedure.

III Engine Parameters

III.1 Primary Engine Parameters The primary engine parameters are permanently displayed on the Engine and Warning Display (EWD), or on the center panel (A300/A310). These parameters are (Figure 2): 

. EPR (Engine Pressure Ratio) and/or N1 (Fan speed) as applicable

. N2 (and N3 for RR engines): High Pressure Compressor rotor speed

. EGT: Exhaust Gas Temperature.

Secondary Engine

The other engine parameters are fuel pressure, and nacelle temperature. Fuel Flow is usually displayed with the main engine parameters on the EWD or on the center panel.

Whereas the tailpipe fire can be very spectacular, it usually has v
temperatures (1000 to 1200°C). However, it can have an impact on the aircra(e.g. damage to the flaps).

Engine Tailpipe Fire

Contrary to the engine fire, the engine tailpipe fire is harder to ident

(i.e. located in the gas path). A tailpipe fire will only occur on ground, du

It is due to an excess of fuel in the combustion chamber,
