***For the LTS101-600A-2, -600A-3, and -600A-3A engine models, the transient measured exhaust gas temperature must not
exceed the takeoff measured exhaust gas temperature for more than 22 seconds. For the LTS101-650B-1, -650B-1A, and
-750B-1 engine models, the transient measured exhaust gas temperature must not exceed the takeoff measured exhaust gas
temperature for more than 22 seconds and never exceed 1499oF (815oC) at any time during normal takeoff operation. For the
LTS101-700D-2, the starting and transient measured gas temperatures must not exceed the takeoff measured gas temperature for
more than 30 seconds.

The transient limits are not to be used for increased power operation during normal takeoff.

(1) Zone temperature limit of 250oF is for mechanical power turbine overspeed trip system mounted on the accessory pad
marked “Alternator”. All other engine models utilize an electronic overspeed system with a 160oF limit for the airframe-
mounted box.

NOTE 8. Fuel pressure limits and oil pressure and temperature limits:

Fuel pressure limits for the LTS101-600A-2, and -600A-3 engine models are 15 p.s.i.a. minimum and
45 p.s.i.a. maximum. For all other engine models, the fuel system provides suction lift capability
without any external assistance. See the applicable engine Installation Instructions for further details.

Oil pressure and temperature (as measured by engine oil temperature bulb located at oil filter
discharge) limits:
