.
At 1000 ft. AGL, reset both EPR gauges to their normal/automatic position by pressing the EPR set knobs in. Turn the autothrottle switch On. Check climb power is selected on TRI and push EPR Lim button if necessary.

Continue with the noise abatement profile.

Make an advisory note in the maintenance log (example: Flt 202, DEN-PHL, Denver bump thrust).
Note: All engine parameters/limitations remain the same during the “Denver Bump” procedure.
TAKEOFF PROCEDURES
Setting Takeoff Thrust
When setting takeoff power in the MD-80, the PF should move the throttles to the vertical position to achieve a stable indication of approximately 1.4 EPR (70% - 80% N2). If autothrottles are to be used for takeoff, the PF will call out “Autothrottles On” and the PM will move the ATS switch to AUTO THROT. The PF will follow-up the throttles to ensure symmetric thrust during engine spool-up. If autothrottles will not be used for takeoff, the PF will advance the throttles in a rapid but smooth manner to takeoff EPR making final EPR adjustments by 60 knots. In either case, the PF will call out “Check Power” and the PM will note the indicated N1 values when takeoff power is set and call out “Power Set, ___%.” (N1 will normally range from 80% to 95% but may be as low as 75%) No adjustments should be made after 60 knots unless engine parameters are exceeded. All takeoff performance is based on having takeoff power set by 60 knots. After takeoff power is set, the Captain will guard the throttles for all takeoffs. All engine indications including EPR, RPM, fuel flow, and EGT should be monitored to determine if the engine is producing proper thrust. An iced-over PT2 probe would result in erroneous EPR indications, with a resulting lower thrust than indicated by the EPR
gauge.
Note: When temperatures are low and engine anti-ice is on for takeoff, cross check the “MINIMUM N1 FOR TAKEOFF” chart in Section 5 or the QRH.
