Sec.  33.73  Power or thrust response.

    The design and construction of the engine must enable an increase--
    (a) From minimum to rated takeoff power or thrust with the maximum 
bleed air and power extraction to be permitted in an aircraft, without 
overtemperature, surge, stall, or other detrimental factors occurring to 
the engine whenever the power control lever is moved from the minimum to 
the maximum position in not more than 1 second, except that the 
Administrator may allow additional time increments for different regimes 
of control operation requiring control scheduling; and
    (b) From the fixed minimum flight idle power lever position when 
provided, or if not provided, from not more than 15 percent of the rated 
takeoff power or thrust available to 95 percent rated takeoff power or 
thrust in not over 5 seconds. The 5-second power or thrust response must 
occur from a stabilized static condition using only the bleed air and 
accessories loads necessary to run the engine. This takeoff rating is 
specified by the applicant and need not include thrust augmentation.
