737NG wing anti-ice
With engine and wing anti-ice selected on, why does the master caution briefly illuminate as the thrust levers advance for take off? ( I know the valves close as the levers advance and the wing AI switches trip off as the aircraft gets airborne.) Seen this a few times on different NG's and can't find a reason.
