Abstract

An aircraft (12) includes a turboshaft engine (14) for powering the aircraft (12); an inlet barrier filter, IBF, (16) for filtering air at an inlet (26) through which the turboshaft engine (14) draws inlet air; a differential pressure transducer (30) for measuring a differential pressure across the IBF (16) during operation of the aircraft (12); and a flight control computer system configured to, during operation of the aircraft (12), periodically calculate a restriction of an airflow through the IBF (16), periodically determine a rate of change of the restriction of the airflow, compare the rate of change to a threshold rate, and provide an alert to a pilot of the aircraft (12) when the determined rate of change exceeds the threshold rate.
