Q

Windshield heating operates according to load shedding logic. What occurs on the ground if only one AC power source is available?

A

Windshield heating is inhibited

17
Q

What is the function of the ADSP PROBES HEATER Switch?

A

To facilitate de-icing on the ground

18
Q

Where is the wing anti-ice temperature displayed?

A

On the MFD Anti-ice Synoptic page

19
Q

What indicates to the flight crew that the ice detectors are sensing ice?

A

An advisory message ICE CONDITION is annunciated on EICAS

20
Q

When would the flight crew accomplish Supplemental Normal 4.2.1 ADSP Heater Switch?

A

During pre-flight, if abnormal ADS-related indications are observed on the PFD/EICAS, or when snow/ice is
observe on any ADSP

21
Q

What must the flight crew accomplish after landing in icing conditions?

A

Select the REF A/I to ALL on the T/O DATASET menu in the MCDU

22
Q

How will the wing and engine anti-ice valves be configured after the automatic detection system has activated dueto ice detection and then icing conditions are no longer sensed by the ice detectors?

A

The wing and engine anti-ice valves will remain open until 5 minutes after icing conditions are no longer
detected

23
Q

What would result from selecting the ICE PROTECTION panel mode selector to ON while the REF A/I is set to OFF on the T/O DATASET menu page in the MCDU?

A

The engine anti-ice valves would open at engine start and EICAS would display an ENG REF A-I DISAG
message

24
Q

How are the Air Data Smart Probes (ADSP) heated?

A

Electrically; automatically powered after the first engine start
