14 CFR 34.62 - Test procedure (propulsion engines).

There is 1 rule appearing in the Federal Register for 14 CFR 34. Select the tab below to view, or View eCFR (GPOAccess)
§ 34.62
Test procedure (propulsion engines).
(a) (1) The engine shall be tested in each of the following engine operating modes which simulate aircraft operation to determine its mass emission rates. The actual power setting, when corrected to standard day conditions, should correspond to the following percentages of rated output. Analytical correction for variations from reference day conditions and minor variations in actual power setting should be specified and/or approved by the Administrator:
Mode Class
TP TF, T3, T8 TSS
Taxi/idle (*) (*) (*)
Takeoff 100 100 100
Climbout 90 85 65
Descent NA NA 15
Approach 30 30 34
*See paragraph (a) of this section.
(2) The taxi/idle operating modes shall be carried out at a power setting of 7% rated thrust unless the Administrator determines that the unique characteristics of an engine model undergoing certification testing at 7% would result in substantially different HC and CO emissions than if the engine model were tested at the manufacturers recommended idle power setting. In such cases the Administrator shall specify an alternative test condition.
(3) The times in mode (TIM) shall be as specified below:
Mode Class
TP TF, T3, T8 TSS
Taxi/idle 26.0 Min. 26.0 Min. 26.0 Min.
Takeoff 0.5 0.7 1.2
Climbout 2.5 2.2 2.0
Descent N/A N/A 1.2
Approach 4.5 4.0 2.3
(b) Emissions testing shall be conducted on warmed-up engines which have achieved a steady operating temperature.
