What EICAS messages will be
presented when entering icing
conditions?
Air Line Pilots Association, International
- ICE CONDITION (blue advisory message)
- SPS/ICE SPEEDS(blue advisory message)
Air Line Pilots Association, International
How can the SPS/ICE SPEEDS
message be cancelled?

How is the ice protection
(electrical) test performed?
Air Line Pilots Association, International
Ice Protection Test (electrical)
• APU and Engine Bleed – CLOSE
NOTE
Wait at least 10 seconds from the time the engine and/or APU Bleed
valves are closed before moving the Ice Detection Test knob.
• Anti-icing buttons (Engine, Wing and Stabilizer) - PRESSED IN
• Ice Detection Override knob – AUTO
• Ice Detection Test knob – 1 then 2
NOTE
The test knob must be held at least 10 seconds in each test position.
For each side, separately check the following EICAS messages:
– BLD 1 (or 2) LOW TEMP
– ICE DET 1 (or 2) FAIL
– ICE CONDITION
• APU bleed – AS REQUIRED
Air Line Pilots Association, International
After closing the bleeds, why
must you wait 10 seconds before
performing the ice protection
(electrical) test?
Air Line Pilots Association, International
To allow the valves to fully
close.
Air Line Pilots Association, International
How is the ice protection
(pneumatic) test performed?
Air Line Pilots Association, International
Ice Protection Test (pneumatic on the ground) PART 1
• Cross Bleed Knob – AUTO
• APU Bleed Valve – CLOSED
• Engine bleeds – OPEN
NOTE
Do not increase above 83% unless oil temperature is 40°C or above
or the engine has been running at idle or taxi for at least eight minutes.
• Thrust Levers – 83% N2
NOTE
If engine vibration increases, advance thrust levers, one at a time, to obtain at
least 60% N1 for 5 seconds and then return to former setting.
• Ice Detection Override knob – ALL
• Ice Detection Test knob – 1 then 2 (no more than 15 secs.)
For each side, separately check:
—
—
—
—
—
OPEN inscriptions in the buttons are illuminated
ICE DET 1 (2) FAIL caution message on EICAS
BLD 1 (2) LOW TEMP caution message on EICAS
ICE CONDITION advisory message on EICAS
X BLEED OPEN advisory message on EICAS
Air Line Pilots Association, International
Ice Protection Test (pneumatic on the ground) PART 2
NOTE
X BLEED OPEN and BLD 1 (2) LOW TEMP message may or may not be seen
during this portion of the test. The test is valid in either case.
• Ice Detection Override knob - AUTO or ENG
— Select ENG if REF A-ICE is selected ON
• Thrust Levers – IDLE
• Engine bleeds – AS REQUIRED
• APU bleed – AS REQUIRED
NOTE
If the first attempt fails, the crew may proceed with a second attempt.
CAUTION
ICE DETECTION OVERRIDE KNOB MUST NOT BE SET TO “ALL” ON GROUND,
EXCEPT DURING TEST.
Air Line Pilots Association, International
How is the ice protection
(pneumatic) test performed
in flight?
Air Line Pilots Association, International
Ice Protection Test (pneumatic in flight)
If the first flight of the day and NO icing conditions exist or are anticipated
for
takeoff and climb, complete the pneumatic portion of the test in flight.
• APU Bleed – CLOSED
• Engine Bleeds – OPEN
- Verify TAT 10°C or below and before reaching 23,000 ft.
• Ice Detection Override knob – ALL for 60 seconds
- Confirm all OPEN inscriptions in the buttons are
illuminated
- Confirm NO ICE-A/ICE ON caution message on EICAS
• Ice Detection Override knob – AUTO
NOTE
X BLEED OPEN advisory message may or may not be seen during this portion
of the test. The test is valid in either case.

Air Line Pilots Association, International
If icing conditions are
anticipated anywhere from
the
gate to 1500 feet what should
be selected on the ice
detection OVERRIDE knob?
Air Line Pilots Association, International
ENG.
Air Line Pilots Association, International
If the ice detection OVERRIDE
is knob is selected to ENG,
what ice protection is
provided?
Air Line Pilots Association, International
Ice Detection OVERRIDE Knob in ENG:
ENGINE AIR INLET
-When engine is running
WING and STAB A/I
-When icing detected; and
-When wheel speed > 25 kts.
Air Line Pilots Association, International
If the ice detection OVERRIDE
is knob is selected to AUTO,
what ice protection is
provided?
Air Line Pilots Association, International
Ice Detection OVERRIDE Knob in AUTO:
ENGINE AIR INLET
-When icing detected
WING and STAB A/I
-When icing detected; and
-When wheel speed >25 kts; or
-When airborne
Air Line Pilots Association, International
If the ice detection OVERRIDE
is knob is selected to ALL,
what ice protection is
provided?
Air Line Pilots Association, International
Ice Detection OVERRIDE Knob in ALL:
ENTIRE BLEED AIR ICE PROTECTION
-Regardless of ice detection.
-On the ground, WING and STAB A/I
are
inhibited below a wheel speed of 25
kts.
Air Line Pilots Association, International
What conditions must be met
for ALL electric sensors to be
heated?
Air Line Pilots Association, International
- One engine running
- TAT when thrust levers
advanced
Air Line Pilots Association, International
When will the pneumatic cross
bleed valve open
automatically if the XBLEED
valve is in AUTO?

Cross bleed engine starts.
Air Line Pilots Association, International
When does the pneumatic
system use high pressure
bleed air?
Air Line Pilots Association, International
