What is the meaning of the A-I WINGSTB ARM Advisory CAS message?
When the engine is at high speed, bleed air is at low temperature. In this case, each AIV regulates pressure at a lower set-point to reduce bleed air extraction. When the engine is at low speed, bleed air is at high temperature.
When the engine is at high speed, bleed air is at high temperature. In this case, each AIV regulates pressure at a lower set-point to reduce bleed air extraction. When the engine is at low speed, bleed air is at low temperature. In this case, each AIV regulates pressure at a higher set-point to increase bleed air extraction.
Ice detector (if applicable) - The ice detector helps the pilot to identify that the airplane is flying in icing conditions. An associated CAS message is displayed whenever ice is detected or a failure on the ice detector has been detected. The pilot remains responsible for recognizing icing conditions in flight, and the primary mean of ice formation detection remains the presence of visible moisture and TAT _____.
The ice detector consists of a probe installed below the left side windshield and exposed to the airstream. As ice accumulates on the sensing element, ice accretion is detected by a change in the sensing element's resonant frequency.
The wing and horizontal stabilizer anti-ice system works independently on each side.

In case of single bleed source operation, the Pneumatic System closes the affected side Pressure Regulating and Shutoff Valve (PRSOV) and opens the Cross Bleed Valve in order to provide airflow to the system.
The wiring logic of the Windshield Heating Control Units (WHCU) uses generators ON/OFF status to control the system. If only a single power source is available (one starter generator failed), the left windshield side has the priority and one of its sections (left or right) is heated as follows:
The Wing and Horizontal Stabilizer Anti-Icing System (WHSAIS) prevents the ice formation and remove the ice formed on the wing and the horizontal-stabilizer leading edges. The Pneumatic System supplies bleed air at controlled temperature and pressure to the WHSAIS.
In order to provide visual means for crew to verify ice formation at night on wing leading edges, a wing inspection light is installed ____ of the fuselage.
In order to avoid leading edge overheating, the Wing and Horizontal Stabilizer Anti-Icing System (WHSAIS) is inhibited on ground when airplane wheel speed is below:
Minimum Airspeed with Wing and Stabilizer Anti-Ice System Inhibited (flap and gear up) is:
The minimum airspeed is the same with the Wing and Stabilizer Anti-Ice System Armed (flap and gear up).
The Engine Anti-Ice (EAI) system is activated via:

The driftdown speed schedule allows the airplane to perform a coordinated turn of _____ bank without the stall warning activation.
Each airplane side has an Anti-ice Valve (AIV) that is a pressure regulating and shut-off valve. There is a pressure transducer downstream of each AIV, which is used to provide feedback for AIV control and also to detect system failures. The Wing and Horizontal Stabilizer Anti-Icing System (WHSAIS) can operate with one AIV opened and the other closed. The WHAIS will then operate in a degraded mode.
The WHAIS operates only if both AIVs are opened.
What is the meaning of the WSHLD 1 (2) HTR FAIL Caution CAS message?
The ADS probes heating system contributes to safe operation under icing conditions preventing ice formation on Integrated Air Data and Stall Protection Probes and Standby Pitot-Static Probe. During normal operation, the knob located on the HEATING control panel is set to AUTO position. In this mode, the probe heating elements will be automatically energized if:
Minimum Airspeed with Wing and Stabilizer Anti-Ice System Uninhibited (flap and gear up) is:
The minimum airspeed for operation in icing conditions is different if the airplane is flying inside the wing and stabilizer anti-ice operational envelope (A-I WINGSTB ON) and if the airplane is flying outside it (A-I WINGSTB INHB or A-I WINGSTB ARM). These speeds provide the airplane the capability to perform a coordinated turn of _____ bank without the stall warning activation. This is especially helpful when performing holding procedures.
