ENGINE LUBRICATION SYSTEM LIMITATIONS
Oil pressure
The oil pressure limits vary as function of the gas generator speed according
to figure 1-5. These oil pressure limits must be respected when engine oil
temperature is between 71 - 120°C.
Transient : 200 psi
NOTE
The engine can run with oil pressure up to 200 psi during or after
a start or if the oil temperature drops significantly below 71°C.
Oil pressure will decrease as oil temperature increases and is not
expected to endure for more than 5 sec. The operation at an oil
pressure above the normal range (up to 200 psi) is permitted for
a period of 10 minutes.
