ICE/RAIN PROTECTION

Question 1

Where are the (HOT) Hold over time charts located

Answer 1

EFB

Question 2

When must a tactile check be accomplished during the walk around

Answer 2

When OAT <6°C and
Visible moisture
Water is present on the wing
The difference between the OAT and Dew point is 3°C or less
The atmospheric conditions have been conductive to frost formation

Question 3

What A/I fluid must be used when operating in conditions with ice pellets adhering to the aircraft?

Answer 3

Only undiluted Type IV fluid may be used during operations in ice pellets

Question 4

True/False: During operations in Ice Pellets, the FAA TYPE IV Time guideline may be used for HOT

Answer 4

False

The Ice Pellet Allowance Time Tables must be used

Question 5

What information must the captain collect if deicing/anti-icing occurred?

Answer 5

Fluid Type, Fluid product name, mixture ratio, time when the final deicing/anti icing application began
TYPE, NAME, MIX, TIME

Question 6

Is it allowable to be manually de-iced while the engines are operating

Answer 6

NO

Question 7

Is it allowable to use cold forced air for loose snow removal from aircraft surfaces

Answer 7

Yes

Does not replace De-ice procedures

Question 8

If operating in active ground icing an abort is accomplished after initiating a takeoff roll, it is allowable to initiate another take off if within the original HOT?

Answer 8

NO

The aircraft must be deiced before attempting another take-off

Question 9

Who has ultimate responsibility for determining whether the aircraft is free of contamination and complies with the clean aircraft concept

Answer 9

The Captian

Question 10

True/False: Take-off during moderate or heavy freezing rain is permitted?

Answer 10

False

Question 11

What are some indications of anti-icing fluid failures

Answer 11

The fluid appears to be opaque rather than transparent and glossy, the ability to discern structural details through the fluid is no longer apparent

Question 12

Where can the crew find instructions on how to configure the aircraft during de-icing/anti-icing operations?

Answer 12

ORH

Question 13

What steps should be taken from if the EICAS message E 1(2) A/I FAIL

Answer 13

Advance the thrust levers to see if the EICAS message goes away and the OPEN inscriptions for the engine anti-ice valves remain open

Question 14

When must ENG REF ANTI-ICE be selected ON when storing the takeoff data

Answer 14

If icing conditions 
Temp ≤10°C 
Visible moisture
Contaminated runway or taxiway
Ceilings ≤1700' AGL

Question 15

Where should the Ice Detection Override be selected after the normal after start flow while taxiing in Icing conditions?
How should the pneumatic panel be configured while taxiing in icing conditoins

Answer 15

ENG
APU Bleed may be open to drive PACKS
EBVs may be closed

Question 16

What are some items to consider when taxiing in icing conditions?

Answer 16

PPG windshields: Should be on
Ice Detection override: ENG
Avoid taxiing in deep snow
Taxi with flaps up
Nose wheel steering should be exercised in both directions
Maintain greater distance from aircraft ahead
Monitor engine vibration

Question 17

What are some items to consider for takeoff in icing conditions?

Answer 17

Engine Ignition should be placed to ON if in standing water ice slush or snow is present on the runway
If the flight crew feels the runway condition could affect the aircrafts ability to accelerate
Both Engine bleeds must be open

Question 18

When climbing in icing conditions what are the preferred FGCP control modes of operation

Answer 18

FLC mode provides stall protection

SPD or VS ensure airspeed does not drop below 200 KIAS or .56mach

Question 19

When is the wing and horizontal stabilizer anti-ice protection inhibited?

Answer 19

On the ground with wheel speed of <25 knots

Question 20

What differences re found in the XR anti-ice system compared to the other EMB-135/145 variants

Answer 20

The XR upper wing had DC powered clear ice detectors

Question 21

When will the clear ice detectors on the 145XR trigger a CLR ICE EICAS message

Answer 21

On the ground only, when clear ice is detected on teh upper surface of the wing

Question 22

What is the functionality of engine lip anti-ice protection in the essential power configuration with a loss of generators?

Answer 22

The engine lip anti-ice system operates continuously and cannot be turned off. The engine lip anti-ice valve is DC powered and fails open

Question 23

During essential power with a loss of all generators, is wing and stabilizer anti-ice protection available?

Answer 23

NO

DC powered and fail closed

Question 24

During ICE TEST A where should the Ice Detection Override be positioned and how long should the test switch be held on each side

Answer 24

ALL

15 Seconds

Question 25

How are the bleeds configured for a takeoff in icing conditions

Answer 25

The engine bleeds should be open and the APU bleed closed
