TCDS E00070EN Page 5 of 10 
 
 
 
 
NOTE 1. ENGINE RATINGS 
 
Engine ratings are based on calibrated test stand performance, and performance calculations are based on accepted parameter correction 
methods documented in the production data folder. These calculations assume the following conditions: 
(1) Static sea level standard conditions of 59° F and 29.92 inches Hg 
(2) US standard atmosphere 1962 (zero humidity) 
(3) No aircraft accessory loads or air extraction. 
(4) Production engine inlet and production flight exhaust system 
(5) Standard lower heating value of 18550 BTU/LB 
(6) No anti-icing; no inlet distortion; no inlet screen losses; and 100% ram recovery. 
 
 
NOTE 2. TEMPERATURE LIMITS 
 
(1) Indicated maximum permissible temperatures are listed below. In addition, the CF34-10E2A1 model incorporates an EGT shunt of 30°C at fan 
speeds above idle. Thus, for an indicated EGT of 1801°F (983°C), the measured EGT is 1747°F (953°C). All CF34-10E/10A series engines are 
certified with a takeoff EGT transient allowance. This allowance applies to normal and maximum takeoff EGT, up to 5.5 °C for 2 seconds, 4.4 °C for 
5 seconds, 3.6 °C for 15 seconds and 2.4 °C for 30 seconds.

NOTE 3. FUEL AND OIL PRESSURE LIMITS 
 
(1) Fuel: For all 10E models, at engine pump inlet: minimum pressure of 5 PSID above the true vapor pressure of the fuel with a 
vapor/liquid ratio of zero with aircraft boost operative. Operating range 5 PSIG to 50 PSIG. At engine motive flow 
discharge: minimum pressure of 150 PSIG at idle or above. Operating range is 150 PSIG to 1209 PSIG. See GE 
Installation Manual GEK 112083 for additional limits. 
 
For 10A models, at engine pump inlet: minimum pressure of 5 PSID above the true vapor pressure of the fuel with a 
vapor/liquid ratio of zero with aircraft boost operative. Operating range 5 PSIG to 50 PSIG. See GE Installation Manual 
GEK 112093 for additional limits. 
(2) Oil:  Minimum oil pressure limit is 25 psid. For oil temperatures less than –20C, the minimum oil pressure is 5 psid for the first 
two minutes following an engine start. After two minutes at idle or if the engine power is increased above idle, the minimum 
oil pressure is 25 psid. See GE Installation Manual GEK 112083 (10E all models), GEK112093 (10A all models) for 
additional limits.

NOTE 10.  POWER BOOST, INJECTION OR AUGMENTATION SYSTEMS AND LIMITS AS APPLICABLE 
This engine is equipped with an automatic power reserve function for takeoff operation with one engine inoperative. During takeoff, 
when the automatic power reserve function is activated, the engine control of the inoperative engine sends an input signal to the 
engine control of the operating engine. Upon receiving this signal, the engine thrust of the operating engine automatically increases 
from normal takeoff (NTO) or lower thrust to the corresponding, pre-determined maximum takeoff (MTO) thrust. Full MTO thrust is 
available to the pilot at any time by throttle selection. 
The engine control sy stem also incorporates schedules that assure a fully degraded engine, during operation at the NTO of lower thrust, 
will achieve the specified MTO thrust without exceeding the engine operating limits when the automatic power reserve  function is 
activated. 
 
 
NOTE 11.  SPECIAL INSTALLATION REQUIREMENT 
(1) The maximum permissible inlet distortion for these engines is specified in GE Installation Manual GEK 112083 (CF34-10E 
all models) and GEK 112093 (CF34-10A all models). Ground operational limits and procedures for operation in crosswind 
are specified in GE Specific Operating Instructions GEK 112084 (CF34-10E all models) and GEK 112094 (CF34-10A all 
models). 
 
(2) Criteria pertaining to the dispatch and maintenance requirements for the engine control systems are specified in the airworthiness 
sections of the Engine Manuals, GEK 112081 (CF34-10E all models) and GEK 112091 (CF34-10A all models), which define 
the various configurations and maximum operating intervals.
