[1] Normal take-off power and Maximum power (two engines) is limited to 5 minutes.
[2] APR power (one engine) is limited to 10 minutes.
[3] ITT must be below 120°C before attempting to ground start engine.
[4] Maximum oil pressure is limited to 156 psi when oil temperature transient is less than 60°C.
[5] Oil pressures (above IDLE) between 25 psi and 45 psi require oil temperature monitoring.
[6] Oil pressure should show positive value during start and may peak beyond 182 psi (max display
value). Oil pressures above 182 psi are displayed as amber dashes. Oil pressure may be greater than 95
psi for a maximum of 10 minutes.
[7] For further details, refer to the Airplane Operating Manual
[8] ITT must be below 90°C before attempting to air start engine.
