(5) Empennage Ice Protection System
(a) Proportioning Unit
A proportioning unit is attached forward of the front spar of the vertical stabilizer.
The proportioning unit divides the fluid flow into three sub branches. For each sub-branch
there is a capillary which ensures that the correct amount of de-icing fluid flows to the related
horizontal or vertical tail porous panel.
(b) Horizontal Tail Ice Protection System
One porous panel is attached to the leading edge of the horizontal tail on the LH side.
Another panel is attached on the RH side. The panels discharge the fluid onto the horizontal
tail through many fine holes.
The panels are bonded to the horizontal tail leading edge. They cannot be removed without
damage.
(c) Vertical Tail Ice Protection System
One porous panel is attached to the leading edge of the vertical tail. The panel discharges
the fluid onto the vertical stabilizer through many fine holes.
The panel is bonded to the vertical tail leading edge. It cannot be removed without damage.
(d) Low Pressure Sensors
Three low pressure sensors are situated between the proportioning unit and the porous
panels on the empennage. If one of these panels is not supplied with sufficient pressure, then
the sensor activates a caution message on the G1000 PFD ("DEIC PRES LO").
