Ice & Rain Protection Flashcards
How many ice detect probes are installed?
Two, one on each side of the lower nose.
How many wing inspection lights are there?
2
Does the wing source automatically transfer to the operating engine in the event of an engine failure?
Yes
Anti-icing system uses intermediate pressure or high pressure bleed air?
High pressure bleed air regulated to 36 psi
What surfaces are being heated by high pressure bleed air
Wing leading edges and engine inlets
At what airspeed must the wing anti-ice be on?
In icing conditions in the air speed is less than 210 kts or the ice Detect CAS message is on. 
What happens to the wing anti-ice valves when electrical power is lost?
The valve is spring loaded to fail closed.
What happens to engine anti-ice valve when electrical power is lost?
The valve spring loaded to fail open
Which ice protection components, probes and sensors are heated electrically?
Left and right pitot-static probes, left and right AOA, standby pitot probe, left and right static port, TAT probe with weight off wheels, windshield, windows, T2 sensors.
When are the ice detect probes receiving electrical power?
When the batteries are on
Amber “ice detected” CAS means what
Ice is detected and one or more anti-systems are not on 
After being de-iced and anti-iced with type 2, 3 or 4, when do you turn on the wing anti-ice?
Just prior to setting take off power
What controls the anti-ice protection system?
Integrated air system controllers (IASC 1 & 2)
Which window is heating during essential power only condition?
Left side window only
What surfaces are considered critical?
Wings and winglets, horizontal and vertical stabilizers, all control surfaces, upper fuselage and engine inlets. (clean aircraft concept: hoar frost on the upper fuselage is not limiting and up to 1/8 of an inch frost due to cold, soaked fuel on the underside of the wing is acceptable. Otherwise, all surfaces must be free of contamination .)
