Response text:

In both AFM and AOM published by SAAB Aircraft AB there is a recommendation, introduced in October 1999, to cycle boots at first sign of ice on the airframe, ref appendix 2. The crew must always monitor the wing for ice and if not all ice is shed then cycle boots more often. There is no possibility to define from temperature, altitude, speed and clouds an advice to the crew, the capability of the boots to shed ice build up on the wing.
