Front 1

The Ice detectors activate the green ICE advisory EICAS message when

Back 1

Airframe icing is detected and both cowl anti icing systems and the wing anti icing system is turned on

Front 2

The wings and cowls are heated to prevent is accretion by

Back 2

14th stage bleed air. Cowls and wings are heated from the respective engine, wings may be heated from either engine

When the WING switch is selected to NORM position, wing temp is maintained at what temp

Back 4

88c

Front 5

Adequate wing anti ice heating is indicated by

Back 5

Illumination of the related green HEAT caption in the annunciator in the WING switch group

The green WING A/ICE ON advisory EICAS message

Front 6

The wing anti ice shutoff valves are operated how

Back 6

Are spring loaded closed, electrically controlled, pneumattically operated

Front 7

The amber WING A/ICE SNSR caution EICAS message indicates

Back 7

A normal or overheat temperature probe in either wing failed

Front 8

The red WING OVHT warning EICAS message indicates

Back 8

The temp of either wing is excessive at any time

Front 9

An amber Wing A/ICE caution EICAS message indicates

Back 9

Bleed-air pressure downstream of the related anti-icing valve is too low and the green HEAT caption has subsequently extinguished

Front 10

While operating wing anti icing in the standby mode heating of each wing is independently controlled by

Back 10

reference to the standby temp sensor

Front 11

The red ANTI-ICE DUCT warning EICAS message indicates

Back 11

A bleed air leak in either 14th stage bleed air line extending from the anti icing valves to the wing roots or a break in the piccolo tube in ether leading edge

Front 12

Selecting COWL ant-icing ON

Back 12

Heats the related engine inlet lip and duct, T2 probe and thrust reverser actuators with 14th stage bleed air

Front 13

Proper operation of both cowl anti icing systems is indicated by

Back 13

The green COWL A/ICE ON advisory EICAS message

illumination of the green ON caption in the related COWL switch light

Front 14

The cowl anti icing pressure regulating shutoff valves are

Back 14

Spring loaded open, electrically controlled, pneumatically operated

Front 15

An amber COWL A/ICE caution message indicates

Back 15

A mismatch in COWL switchlight selection and pressure in the related cowl anti icing system (switch ON with low pressure or switch off with pressure detected)

Front 16

Air data probes on the left forward fuselage are supplied heating power from

Back 16

AC essential bus

Front 17

The TAT probe is heated

Back 17

At all times power is available from AC bus 1

Front 18

Selecting a PROBES switch off while airborne

Back 18

Causes display of all onside probe heating messages

Front 19

Air data probe heating is inhibited while on the ground if

Back 19

Both IDG generators are not operating

The passenger door is open

When the WSHLD/WIND swithches are selected to HI

Back 20

Only the windshield increases to approximately 58c

Front 21

An amber WSHLD HEAT caution EICAS message indicates the related windshield

Back 21

Has over heated, has an open or shorted temp sensor, heating power failed, or the controller failed.
