NOTE 16. A takeoff thrust setting limited to the normal takeoff rating of 16,400 lb. static thrust at sea level, flat rated
to 77oF ambient temperature has been established for normal takeoff operation.
When the automatic reset mechanism in the fuel control is utilized, operation to the normal takeoff
operating limits will prevent the engine from exceeding the maximum takeoff rating operating limits when
the reset mechanism is actuated.
The time limit at the normal takeoff rating is 5 minutes and shall include any time accumulated at the
maximum takeoff rating.
NOTE 17. DELETED.
NOTE 18. Turbine outlet gas temperature thermocouple box P/N 792863, cable assemblies P/N 792864 or P/N
798380, and turbine discharge gas pressure averaging probe assemblies P/N 793272 or P/N 793274
should be used for JT8D-15A, -17A, and -17AR engines and for JT8D-11 engines that have incorporated
P&W Service Bulletin No. 5455.
NOTE 19. The 5 minute takeoff time may be extended to 10 minutes for one engine inoperative or shutdown for
engines which have incorporated all the features specified in P&W Service Bulletin Numbers 5514, 5643
