GE CF6 Nacelle Temperature
 

My aircraft is a CF6 powered A330.Anyone know why the engine nacelle temperatures are displayed to the crew?As the reading tends to sit around the 200 degree C mark it's hardly icing related.Also where in the engine is the reading measured?
Ta very much.

Not quite sure where the nacelle temp sensors are physically located but an abnormally high nacelle temp indication on the CF6 would point to an air leak, usually from a flange coupling in the plumbing and should be investigated.

On 50C2 sensor situated in the lower left core door sensing flow of air around the engine core

As HD states any high increase can be indicative of engine abnormality,usually a severe hot air leak.

Temp varies with TAT and N1 On ground N1>60% or in climb after 3 minutes of constant thrust all readings should be within 50C of each other if not think of investigating

Is there not a chart base on tat and N1 to give recommended Nacelle temp and an abnormal procedure in your AOM?

Disregard Nacelle temp in the cruise and descent as indications are normally unrealiable.

Hope it helps

Should have a Flight Engineer, then you'd know what half these gauges meant!
