FAR 23.157 : Rate of roll.
(a) Takeo.. It must be possible, using a favorable combination of controls, to roll the airplane from a steady 30'banked turn through an angle of 60', so as to reverse the direction of the turn within–
(1)
For an airplane of 6,000 pounds or less maximum weight, 5 seconds from ini-tiation of roll; and
(2)
For an airplane of over 6,000 pounds maximum weight, W+500 seconds, but
1300
not more than 10 seconds, where W is the weight in pounds.
(b)
The requirement of paragraph (a) of this section must be met when rolling the airplane in each direction with–

airplane from a steady 30banked turn through an angle of 60, so as to reverse the direction of the turn within :
