message remains cyan

when first turned on?

2.5 minutes

What does eng anti-ice

cold L-R mean in flight?

Either undertemp of engine inlet

Or stator anti-ice valve did not open

anti-ice be turned on?

Visible moisture +5 to - 35C RAT

When should engine

anti-ice be turned on?

Visible moisture +10 to -35C RAT

Can you use the anti-ice

system to deice the wings?

Prohibited

Why does the engine anti-ice

must be turned on first

before the wing anti-ice?

Need to open anti-ice engine stab valve

first to get through the wing

When do you get the cyan

cold messages in flight?

a) When you first turn it on

b) Whenever bleed air is shutoff

due to malfunction (result message)

Which of stab or wing

anti-ice X-flow valve is

monitored on EICAS?

Wing

When is wing anti-ice

X-flow cyan?

When the valve is open after

being selected open

When will you get wing

A/I crossflow open message?

When the valve remains open after

being selected closed

How would you know if

the X-flow valve did not open?

Would find out indirectly with

stab anti-ice cold messages

On what bus is the

bleed detection?

Main DC

What closes for

a wing bleed leak?

Wing anti-ice valve

What valves close

for a stab bleed leak?

left and right stab anti-ice valves

What valves close for

a supply bleed leak?

Left and right wing anti-ice

Left and right stab anti-ice

What cyan message come

as a result of a wing bleed leak?

Wing anti-ice cold L-R

What valve close during

an ACM bleed leak?

Left and right mass flow valves

BCV's (bleed control valve)

Max altitude to use anti-ice

FL 410

Min airspeed in icing

180 kts

Max OAT on the ground

to have anti-ice on

+20C (68F)

Except preflight test

What is recommended when

taxiing through slush and ice?

Leave flaps up until completing T/O checklist, to prevent ice contamination on the flaps surface

What is recommended with

the brakes taxiing through

slush and ice?

Heat them within the last mile of taxi to remove excess water that may freeze after T/O

What should you do with the

landing gear if you taxied

in ice and slush?

Leave gear down until 200 Kts to aid in clearing moisture and slush from gear

Minimum holding speed in icing

180 Kts

Max water/slush allowed on the runway for the Sovereign?

0.4 inches (1 cm)

(Advisory section)

On what bus are

the windshields?

How can you check a failed

sensor on the windshields?

What is the normal

windshield temperature?

What is the windshield o'temp?

140F

What comes on when you turn

on the engine anti-ice?

 a) Nacelle heat (bleed air)

b) 1st set of stator vanes (P2.8)

d) Eng/stab anti-ice valve (bleed air)

e) Rat probes (electrical)

f) Allows cold messages

Can you get pitot/static cold

L-R-stby in flight?

No, this message would be amber instead

What monitors the case

around the AOA probe?

Not monitored

When is using X-flow

prohibited?

Wing or stab bleed leak

If the wing bleed leak message does not extinguish, the procedure is to turn off the opposite wing anti-ice. Why?

Since one wing can not be anti-iced,

the procedure is to match the condition

for asymetry

What is a PRSOV?

a) Pressure regulator

b) Temperature regulator

c) Shutoff valve

How do you define

visible moisture?

Visibility less than 1 mile

Why is windshield heat

not available in emer?

Due to high amps loads, left and

right pitot/static are not on the emer bus either. (only stby is).

Since this require an exit from icing conditions, Cessna decided to leave the windshield heat off emer bus also

What do you turn on with the

PITOT/STATIC  switches?

Pitot tubes

Static ports

AOA vanes

When are the AOA cases heated?

When the avionics switch is ON

When are the RAT probes heated?

When you turn on the ENGINE/STAB

anti-ice switches ON

Does the crossflow shutoff valve

fail close or open with loss of DC?

Fails closed

Why does the AFM ask to heat the brakes

within the last mile of taxi in

cold weather and contaminated taxiway?

Short answer:

To remove excess water

Longer answer:

Carbon brakes are "hygroscopic",

meaning it absorbs liquids.

Once the still wet wheel assemblies get colder temperature, the liquids spread further apart between the rotors and stators and lock the brakes solidly.
