NOTE 4: The thrust values are defined as Ideal at ICAO Standard Atmosphere conditions and assume an Ideal inlet (100%
recovery) and Ideal exhaust system (no internal pressure or external scrubbing losses, Cv=1.0), no fan or compressor bleed or
leakage, and no load on accessory drives. Takeoff thrust is flat rated to 86 degrees Fahrenheit. Maximum Continuous thrust is
flat rated to 77 degrees Fahrenheit.
For both the PW6122A and PW6124A : The uninstalled thrust values are based on static test stand operation under the
following conditions: the engine inlet is a Pratt & Whitney Production hardwall bellmouth (P/N XR-588946-2) with 0.998
inlet recovery, Production Exhaust System (P/Ns AP6151-1; left hand nacelle door, AP6151-2; right hand nacelle door and
AP6155; common nozzle assembly) with no compressor air bleed, no accessory power extraction. The Ideal and Installed
thrust levels are derived using engine performance simulation CCD0850-03.0.
For the PW6122A: Installed values for Take-off and Maximum Continuous thrust are 21,330 pounds and 19,570 pounds,
respectively at Sea Level Static, ICAO Standard Atmospheric Conditions.
For the PW6124A : Installed values for Take-off and Maximum Continuous thrust are 22,980 pounds and 20,260 pounds,
spectively at Sea Level Static, ICAO Standard Atmospheric Conditions. re
NOTE 5, PRESSURES
Fuel pressure limits Fuel pressure at the engine fuel pump inlet during operation shall be maintained at not less
than 5.0 psi above the true vapor pressure of the fuel but not greater than 70 psi above
absolute ambient pressure, with a vapor/liquid ratio of zero. The maximum allowable
pressure at the fuel pump inlet after shutdown is 225 psig.

3. There are no oil pressure limits below ground idle.
4. Temporary interruption associated with negative “g” operation is limited to 30 seconds
maximum. Normal oil pressure will be restored rapidly once the negative "g" effect
has been eliminated.

and 6924 lb.-in. at 4800 rpm maximum impact torque. The engine starter drive shear section is designed to
shear at a static torque value of 11,280 - 12,972 in.-lbs.
** Maximum allowable continuous torque values are equivalent to 175 horsepower at any engine speed at or

NOTE 7:
The minimum N1 certified for operation in icing conditions is 1700 rpm.
NOTE 8:
This engine is certified with Time Limited Dispatch. FADEC system faults fall into 4 categories as follows:
1) No Dispatch. 2) Short Term Dispatch. 3) Long Term Dispatch. 4) Unlimited Dispatch. Details on the Short
and Long Term Dispatch intervals are provided in the Installation and Operating Manual, Section 5.12 and in
Chapter 5 of the PW6000 Series Engine Manual. Lightning protection requirements and electromagnetic
interference emitted by the electronic engine control system, including cables, are specified in the Installation
and Operating manual, Section 5.12.
