Abstract

A method and an apparatus for initiating a run-up procedure for a jet engine to avoid engine icing, the method comprising the following steps of providing at least one surface element that is made of a material suitable for ice in atmospheric air to freeze on, said element having a predetermined surface area moving said at least one surface element through the atmospheric air at a predetermined velocity for a predetermined period of time to enable ice to freeze thereon measuring a thickness or mass of adhered ice to said at least one surface element by means of a measurement device configured therefore after said predetermined period of time, said measurement device being arranged to calculate the concentration of supercooled precipitation and snow in the atmospheric air; and comparing the calculated concentration of freezing precipitation with the specifications of the jet engine.
