ICE/RAIN PROTECTION Flashcards
Where are the (HOT) Hold over time charts located
EFB
When must a tactile check be accomplished during the walk around
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
What A/I fluid must be used when operating in conditions with ice pellets adhering to the aircraft?
Only undiluted Type IV fluid may be used during operations in ice pellets
True/False: During operations in Ice Pellets, the FAA TYPE IV Time guideline may be used for HOT
False
The Ice Pellet Allowance Time Tables must be used
What information must the captain collect if deicing/anti-icing occurred?
Fluid Type, Fluid product name, mixture ratio, time when the final deicing/anti icing application began
TYPE, NAME, MIX, TIME
Is it allowable to be manually de-iced while the engines are operating
NO
Is it allowable to use cold forced air for loose snow removal from aircraft surfaces
Yes
Does not replace De-ice procedures
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?
NO
The aircraft must be deiced before attempting another take-off
Who has ultimate responsibility for determining whether the aircraft is free of contamination and complies with the clean aircraft concept
The Captian
True/False: Take-off during moderate or heavy freezing rain is permitted?
False
What are some indications of anti-icing fluid failures
The fluid appears to be opaque rather than transparent and glossy, the ability to discern structural details through the fluid is no longer apparent
Where can the crew find instructions on how to configure the aircraft during de-icing/anti-icing operations?
ORH
What steps should be taken from if the EICAS message E 1(2) A/I FAIL
Advance the thrust levers to see if the EICAS message goes away and the OPEN inscriptions for the engine anti-ice valves remain open
When must ENG REF ANTI-ICE be selected ON when storing the takeoff data
If icing conditions Temp ≤10°C Visible moisture Contaminated runway or taxiway Ceilings ≤1700' AGL
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
ENG
APU Bleed may be open to drive PACKS
EBVs may be closed
What are some items to consider when taxiing in icing conditions?
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
What are some items to consider for takeoff in icing conditions?
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
When climbing in icing conditions what are the preferred FGCP control modes of operation
FLC mode provides stall protection
SPD or VS ensure airspeed does not drop below 200 KIAS or .56mach
When is the wing and horizontal stabilizer anti-ice protection inhibited?
On the ground with wheel speed of <25 knots
What differences re found in the XR anti-ice system compared to the other EMB-135/145 variants
The XR upper wing had DC powered clear ice detectors
When will the clear ice detectors on the 145XR trigger a CLR ICE EICAS message
On the ground only, when clear ice is detected on teh upper surface of the wing
What is the functionality of engine lip anti-ice protection in the essential power configuration with a loss of generators?
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
During essential power with a loss of all generators, is wing and stabilizer anti-ice protection available?
NO
DC powered and fail closed
During ICE TEST A where should the Ice Detection Override be positioned and how long should the test switch be held on each side
ALL
15 Seconds
How are the bleeds configured for a takeoff in icing conditions
The engine bleeds should be open and the APU bleed closed
Is it possible to use the APU bleed for air conditioning while taxiing in icing conditions
Yes
When is engine lip anti-ice
Whenever the temperature is ≤ 10°C and at least one form of visible moisture is present
What should be checked when conducting and Ice Test A
4 OPEN
ICE CONDITION
ICE DET FAIL
BLD LOW TEMP
What should be checked when conducting the inflight portion of ice test B
4 OPEN
NO ICE-A/I ON
At what altitudes and temp range should the in-flight portion of Ice Test B be accomplished?
TAT <10°C
2000’AGL to 23,000’MSL
