B737 Anti-Ice Protection

Illumination of a window OVERHEAT light indicates: An overheat condition is detected. Electrical power to the window is interrupted. Both (a) and (b) are correct.

When operating on standby power, the probe heat lights do not indicate system status: True. False.

Reference illumination of a COWL ANTI-ICE light: Green indicates normal engine anti-ice operation. Amber indicates overpressure in the duct downstream of the cowl anti-ice valve. Amber indicates that engine anti-ice must be switched off.

If a wing anti-ice VALVE OPEN light is bright blue, this normally indicates: Wing anti-ice valve is open. Wing anti-ice valve is in transit. Wing anti-ice valve is closed.

The rain removal system for the forward windows consists of: Windshield wipers only. Windshield wipers and a pilot-controlled liquid rain repellant system. Windshield wipers and a permanent rain repellant coating on the windows.

The wing anti-ice system provides protection for: The three inboard leading edge slats only. The three inboard leading edge slats and the leading edge flaps. The three inboard leading edge slats. the leading edge flaps and the outboard leading edge slats.

Which statement is true regarding the use of anti-ice. If the WING ANTI-ICE switch is selected ON in the air, stick-shaker logic is set for icing conditions for the remainder of the flight, regardless of subsequent WING ANTI-ICE switch position. With the ENG ANTI-ICE selected ON, stick shaker logic is set for icing conditions. This logic returns to normal with ENG ANTI-ICE selected OFF if WING ANTI-ICE has not been used in flight. Both (a) and (b) are correct.

Which of the following is considered icing conditions. OAT +05 degrees C, Wind calm, Vis 5 miles in haze. TAT +08 degrees C, Vis 1 mile in fog. OAT+ 12 C, Vis 1 mile in light rain.

The rain removal system consists of: A permanent rain repellent coating on the windshields and wipers. A bottled solution located behind the captain’s seat. Rain repellent switches located on the forward overhead panel. All of the above are correct.

Illumination of an amber COWL ANTI-ICE light indicates: An overpressure condition in duct downstream of engine cowl anti-ice valve. An over temperature condition in duct downstream of engine cowl anti-ice valve. The related cowl anti-ice valve is open. The cowl anti-ice valve position disagrees with the respective engine anti-ice switch position.

Refer to the thermal anti-ice TAI Upper Display Unit indications. What does a TAI indication shown at the top left side of each display indicate. If it is amber, an overtemperature condition exists in the duct downstream of the engine cowl anti-ice valve. If it is amber, an overtemperature condition exists in the duct downstream of the engine cowl anti-ice valve. If it is green, the cowl anti-ice valve(s) is open. All of the above are correct.

The Wing Anti-Ice system provides bleed air to all leading edge slats. True. False.

When are the ENGINE ANTI-ICE switches turned ON if icing conditions exist on the ground. When cleared onto the runway. During taxi out. After takeoff. During the after engine start procedure.

Which window(s) are heated with the LEFT FWD WINDOW HEAT switch ON?. L2, L3, L4,L5. L1, L2, L3. L1, L2, L3, L4, L5. L1 only.

How should you use Wing Anti-Ice?. On the ground, should be turned on whenever icing conditions exist or anticipated, unless the airplane is protected by the application of Type II or Type IV fluid. Primarily as a de-icer in flight. Only recommended below approximately FL350. All of the above are correct.

In night, what is the primary method recommended for operating the wing anti-ice system. As a de-icer. As an anti-icer.

The R ELEV PITOT light is illuminated. What does this indicate?. The right elevator pitot probe is blocked. A malfunction in the pilot probe system. The right elevator pitot probe is not heated. Both a and b are correct.

How are the Alpha Vanes heated?. By actuating the LEFT or RIGHT FWD window heat switches. Whenever wing anti-ice is being used. Whenever the alternate static ports are heated. By turning on the relevant PROBE HEAT switch(s).

How are the Alpha Vanes heated?. By actuating the LEFT or RIGHT FWD window heat switches. Whenever wing anti-ice is being used. Whenever the alternate static ports are heated. By turning on the relevant PROBE HEAT switch(s).

Which pilot probes and sensors are not heated?. The elevator pilot probes. The static ports. The Captain's pitot probe. The First Officer's pitot probe.

What is the maximum airspeed limit with a WINDOW OVERHEAT situation?. 250 KIAS. 280 KIAS. 250 KIAS below 10,000 feet. 280 KIAS below 10,000 feet.

The window heat PWR TEST: Must be tested before each flight. Tests the L1 and R1 windows only. Provides a confidence test. Can be used if all green window heat lights are on.

When operating on standby power, both the captain's and first officer's pilot probe is heated. True. False.
