1. A method of indicating the presence of liquid moisture in an airflow, comprising:
- sensing mass flow rate data of an airflow;
sensing a first heat removed from a first heated temperature sensor, the first heat removed including heat removed by the airflow from which liquid moisture has not been removed;
coupling the sensed mass flow rate data and the first sensed heat removed to a computer; and
computing in the computer, as a function of the mass flow rate data and the first sensed heat removed, the presence of liquid moisture in the airflow.

Abstract
A sensor for detecting icing conditions in an airstream includes a flow housing mounted on an aircraft and in which one or more probes are mounted. At least one of the probes subjected to impingement of the airstream and liquid moisture droplets in such airstream. The heat removal, or cooling effect on the probe in the airstream carrying liquid droplets is determined. A temperature signal indicating the airstream temperature is combined with signals from the at least one probe for determining whether or not icing conditions are present.
