ENGINE JET PIPE/PYLON
OVERHEAT DETECTION
Engine jet pipe/pylon overheat detection gives
a visual cockpit indication of an overheat in
the engine jet pipe (exhaust) and pylon areas.
The system (see Figure 8-11) consists of:
• Two jet pipe/pylon overheat detection units
• An engine jet pipe/pylon overheat panel
• Two detection loops per engine
The engine jet pipe/pylon panel is located on
the top right corner of the center instrument
panel. It incorporates four press-to-test switch-
lights, two labeled “OVHT” and two labeled
“OVHT WARN FAIL.”
The detection loops are similar to the ones on
the engine and APU fire detection system.
One detection loop is located around the
tailpipe section of the engine. The other is lo-
cated in the area where the engine wiring and
plumbing pass through the pylon.
