Engine System
Low Idle Oil Pressure
OIL PRESS Caution
1. If In-Flight .................................. LAND AS SOON AS PRACTICAL
Amplification
Oil pressure between 10 psi and 30 psi at or above 1000 RPM
This message will appear prior to engine start and should clear after
engine start.
Manifold Pressure High
MAN PRESSURE Caution
1. Power Lever ........................................ REDUCE to less than 36.5"
2. Flight ............................................................................ CONTINUE
If noticeable surging is present:
3. Complete Overboost / Pressure Relief Valve Emergency Checklist
Amplification
Manifold Pressure has exceeded caution limits. High Manifold
Pressure may be a result of cold oil and the affect of high associated
oil pressure on the wastegate controller. Maintain power at or below
36.5" by power lever management. If High Manifold Pressure persists
when oil temperatures are greater than 150°F, MAP controller requires
a maintenance adjustment. If engine surges are associated, MAP may
be exceeding pressure relief valve (pop-off valve) threshold. Relief
valve will protect induction manifolds from excessive pressure, but it
may be a sign of a failed closed wastegate; if this is observed or
suspected, complete the Overboost / Pressure Relief Valve
emergency checklist.
