GENERAL
The aircraft is fully equipped for all
−
weather opera-
tion.
The ice and rain protection system is divided into:
−
Wing and stabilizer (boot) de
−
icing.
−
Engine anti
−
icing.
−
Propeller de
−
icing.
−
Windshield heating.
−
Windshield wipers.
−
Pitot tubes, Outside Air Temperature probe
(OAT) and angle of attack sensor heating.
Air bleed and electrical power, mainly from the
115VAC wild frequency system, is used
for ice and rain protection. Bleed air is used for the
wing and stabilizer inflatable boots, the engine split
lip and inlet guide vanes. Electrical power is used
for the remainder of the ice and rain protection sys-
tems.
All ice and rain protection systems are controlled
from the overhead panel except for the main pitot
tubes, temperature probe and angle of attack sen-
sors which are powered automatically as soon as
one AC generator is on line.
There are also caution lights advising flight crew of
any system fault. When any caution light is illumi-
nated, the ICE PROT MASTER CAUTION light is
activated.
