Engine Power Loss, Sustained Negative "G" Loading - Mooney M20V Acclaim Ultra Pilot Operating Handbook

SECTION III
EMERGENCY PROCEDURES
At altitudes above 18,000 ft., an overrich mixture may result if the turbocharger fails and
Excessive engine cooling may be experienced during long descents resulting in
low engine oil and cylinder head temperatures. This may result in the engine not
accelerating properly when power is reapplied. If oil or cylinder head tempera-
tures are excessively low then the engine should be operated at partial power un-
til the temperatures are sufficient for full power operation.

ENGINE POWER LOSS, SUSTAINED NEGATIVE "g" LOADING

DO NOT INTENTIONALLY OPERATE IN NEGATIVE "g" LOADING.
Per Continental Motors specifications the Model TSIO- 550 series engine is NOT APPROVED
for continuous negative or zero "g" operation and operation in that environment is prohibited.
Depending on the loading and amount of time encountered (more than normally encountered in
gusts) the engine may quit due to low oil pressure. Upon return to positive loading the engine will
normally restart on its own but may require some leaning of the mixture at very high altitudes for
restart. If negative load conditions are unavoidably encountered, the following procedures are
recommended.
