Advance slowly. Check that RPM and EGT follow
thrust lever movement.
Operate engine normally or at a reduced thrust setting
which is surge and stall free.
Condition: Engine oil pressure is in the yellow band with takeoff
thrust set, LOW OIL PRESSURE light illuminated, or
engine oil pressure is at or below the red radial.
If engine oil pressure is in the yellow band with takeoff
thrust set:
DO NOT TAKEOFF.
If engine oil pressure is at or below the red radial:
Accomplish the ENGINE FAILURE/SHUTDOWN checklist.
