REFLECTOR: Oil Temps - Ground Ops

John and I are starting to get real data from taxing around.  Wanted to
bounce some numbers off the "collectively wisdom".

 

With an OAT of 103 deg F we got oil temps to around 230 after, 10 minutes of
taxing, one long runup and 40 knot taxi test down the runway.  We then went
to the compass rose and sat for about 1-2 minutes before we shutdown.

 

We then swung the compass for about 30 minutes, restarted, taxi back down,
another long runup, 40 knot taxi test on the runway, taxied back to the
hanger and we were at 220 deg F.

 

CHTs never went above 350 deg F, most were in the high 200s for the idling
parts.

 

We have an IO-550 with the stock cooler on the engine (no ducting) and the
standard nose cooler.

 

Comments?
