Q

OIL PX
+
Normal Oil PX is ___ to ___ PSIG at power settings above 27,000 RPM (72%) N1, Oil PX below ____ PSIG is undesirable, and may be used only for completion of a flight, and then at a reduced power setting. Low Oil PX should be corrected prior to next flight. During ground operations, Oil PX below ____ PSIG require engine shutdown; during flight, Oil PX below ____ PSIG is unsafe and requires either engine shutdown or use of minimum power until a landing can be made.
