Propeller deicing
Propeller deicing is accomplished through electrical heating of blade roots. This
system
operates cyclically and alternately on the inboard and outboard zones of all
blades when PROP DE ICE system is activated either manually or automatically.
Each cycle is 180 seconds long. The cycles continue as long as the system is
activated.
The table hereafter gives the CAS messages and the status light colors
corresponding to the state of the system.
