I'm referring to the "10 seconds" speed monitoring process described on page 55 of BEA's Interim Report no.1 and again on page 40 of I.R.#3. It is triggered by a decrease of more than 30 kt in one second of the “polled” speed value. The polled speed value is the "median" or middle value of three valid ADR's or, if one ADR has been rejected, the mean of the two remaining values.
