1. A method comprising:
- receiving a plurality of temperature measurements from a plurality of temperature sensors coupled to an aircraft;
determining first temperature metrics based on the plurality of temperature measurements;
counting a number of the first temperature metrics that are within a specified temperature range to establish a first count of the first temperature metrics;
determining whether the first count is greater than a first threshold count value; and
when the first count is greater than or equal to the first threshold count value, initiating generation of an icing output signal to activate an ice control system of the aircraft.

Abstract
A method includes receiving a plurality of temperature measurements from temperature sensors of an aircraft. The method includes determining whether a first count of one or more first temperature metrics that are within a temperature range is greater than a first threshold. The one or more temperature metrics are derived from the plurality of temperature measurements. The method includes initiating generating an icing output signal when the first count is greater than or equal to the first threshold.
