Flashcards in 3. Anti-Ice/Rain Deck (16):
1

 Recall applicable AIR SD symbology and color-coding

Wing/Tail Anti-Ice

Q image thumb

Blank – Off

White – Commanded on or commanded off with system pressurized

Red – Manifold failed

2

Recall applicable AIR SD symbology and color-coding

Wing/Tail Anti-Ice Bleed Air

Q image thumb

Blank – Anti-Ice off

White – On the ground, anti-ice is commanded on or anti-ice is commanded off with system pressurized

Green – Anti-ice commanded on in flight

Amber – Anti-ice bleed air temp out of limits

Recall applicable AIR SD symbology and color-coding

Engine Bleed Air Pressure

Q image thumb

White – Normal

Amber – Exceeds limits

4

5

Recall applicable AIR SD symbology and color-coding

Isolation Valve

Q image thumb

White – Commanded closed

Green – Commanded open

Amber – Valve position disagrees with commanded position

6

Recall applicable AIR SD symbology and color-coding

Engine Bleed Air Manifold

Q image thumb

White – No anti-ice

Green – Anti-ice available

Red – Burst duct in tail compartment

 

7

Recall applicable AIR SD symbology and color-coding

Wing/Tail Anti-Ice Valves

Q image thumb

Blank - Closed

White – On with no pressure. Alternate system is pressurized and "A" appears

Green – On

Amber – Commanded position disagrees with actual position when in flight. DISAG appears

Red – Manifold failed

8

Recall conditions which require the use of engine anti-ice

  1. OAT is 6º or below (10º or below in flight) and any of the following conditions exist:
  2. Visible moisture (clouds, rain, snow, sleet, ice crystals, fog when visibility is 1 mile or less, etc) is present, or
  3. 3º or less temperature/dew point spread, or
  4. Ice, snow, slush or standing water is present on the ramps, taxiways or runways

9

Recall engine run-up requirements during icing conditions

Run the engines to a minimum of 40% N1 for approximately 10 seconds at intervals no greater than 60 minutes

Additionally, a standing takeoff is required during icing conditions and is accomplished by holding the brakes while in position on the assigned runway until the engines are stabilized at, or above, 50% N1 before the start of the takeoff roll

10

Recall function of the AIR DATA Heat pushbutton

Q image thumb

OFF (amber light) -- all air data system heaters are off

 Dark when all heater circuits for pitots, rudder limiter, stall probes, static ports, and RAT probes are energized

**Note: RAT probe heat is inhibited during ground operations

11

Recall function of the WING ICE DET switch

Q image thumb

RESET – resets system and removes WING ICE DETECTED alert from the EAD. System will not reset if ice remains on the sensors

TEST – tests the wing ice detection system

**Note: Wing ice detection system functions on the ground only and alerts the pilots to the presence of wing upper surface ice. It is inhibited during takeoff, landing and in flight

**Note: Do not takeoff with "WING ICE DETECTED" alert displayed

12

Recall which cockpit windows are electrically heated and/or anti-fogged

The three pilot windshields are electrically anti-iced and anti-fogged

The clearview and overhead windows are also anti-fogged

13

Recall which control surfaces are anti-iced with engine bleed air

Q image thumb

Wing slats and horizontal stab leading edge—from either or both engines

**Note: Airfoil anti-ice WILL operate with nosegear extension, however, normal procedures do not require its use prior to takeoff. Use airfoil anti-ice whenever icing conditions exist in flight.

14

Recall which engine components are anti-iced

Q image thumb

Engine anti-ice systems are independent of the airfoil anti-ice systems and provide ground and in-flight anti-ice heat to their respective engine nose cowl

15

Recall function of the WINDSHIELD ANTI-FOG switch

Q image thumb

OFF – Turns off windshield, clearview and overhead anti-fog

ON – Turns on windshield, clearview and overhead anti-fog

16

Recall function of the WINDSHIELD ANTI-ICE switch

Q image thumb

OFF – Turns off windshield anti-ice

ON – Turns on windshield anti-ice
