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. ITT must be below 90_C before attempting to air start engine.
5. Maximum oil pressure is limited to 156 psi when oil temperature transient is
less than 60_C.
6. Oil pressures (above IDLE) between 25 psi and 45 psi require oil temperature monitoring.
7. Oil pressures 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.
