7.A.2.Gyros or angular rate sensors, having any of the following and specially designed components therefor:

N.B. For angular or rotational accelerometers, see 7.A.1.b.
a. Specified to function at linear acceleration levels less than or equal to 100 g and having any of the following:
1. An angular rate range of less than 500 degrees per second and having any of the following:
a. A "bias" "stability" of less (better) than 0.5 degree per hour, when measured in a 1 g environment over a period of one month, and with respect to a fixed calibration value; or
b. An "angle random walk" of less (better) than or equal to 0.0035 degree per square root hour; or
Note 7.A.2.a.1.b. does not apply to "spinning mass gyros".
a. 2. An angular rate range greater than or equal to 500 degrees per second and having any of the following:
a. A "bias" "stability" of less (better) than 4 degrees per hour, when measured in a 1 g environment over a period of three minutes, and with respect to a fixed calibration value; or
a. 2. b. An "angle random walk" of less (better) than or equal to 0.1 degree per square root hour; or
Note 7.A.2.a.2.b. does not apply to "spinning mass gyros".
b. Specified to function at linear acceleration levels exceeding 100 g.
