-
the cyan dot which indicates the lever configuration comes on.

 (2) No Configuration Indication
 When no valid configuration data is available from the DMC two amber crosses replace the lever position indicator.
R 1EFF : 001-049, 051-099, 101-105, 151-199, 1 27-85-00Page 9 1201-299, 301-302, 1May 01/05 1 1 1CES 1R **ON A/C 106-149, 303-399, 401-499,

 When the slats move, the upper display unit (Ref. 31-66-00) shows:
 -
the S indication in white

 -
the position indication of the flap and slat control lever as 0, 1 (1 + F when the flap auto-command function is engaged), 2, 3 or FULL in cyan

 -
the slat symbol in green

 -a cyan symbol below the related white point of the new slat position selection.
 When the slats reach their new position:
 -
the slat symbol is shown around the related white point

 -
the position indication of the flap and slat control lever changes from cyan to green

 -
the cyan symbol below the related white point goes out of view.

 If the slats do not move to the correct position:

 -
the S indication changes from white to amber

 -
the slat symbol changes from green to amber

 -
the position indication of the flap and slat control lever stays cyan

 -
the cyan symbol stays below the related white point of the slat position selection.

 A. Slat Protection
 (1) Slat Lock
 If the Wing Tip Brakes (WTB) lock the slat transmission systems (for example in an asymmetry condition (Ref. 27-81-00)):
 -
the white S indication changes to amber

 -
the slat symbol changes to amber

 -an amber S LOCKED message comes on above the S indication
 -
the position indication of the flap and slat control lever stays cyan

 -
the cyan symbol stays below the related white point of the slat position selection.

R  (2) Alpha-Lock/Speed Baulk 
R 
R  The Alpha-Lock/Speed Baulk function prevents the retraction of the 
R  slats when the aircraft is operating outside specified flight 
R  parameters (Ref. 27-81-00). If the flap and slat position lever is 
R  moved to the 0 position and the function operates (for example if the 
R  Corrected Angle of Attack (CAoA) is too large or the Computed Air 
R  Speed (CAS) is too low): 
R  - a green flashing A LOCK message comes on above the S indication 
R  - the green slat symbol stays at position 1 and flashes 
R  - the cyan position selected symbol stays on 
R  - the position indication 0 of the flap and slat control lever stays 
R  cyan. 
R  (3) System Failure 
R 
R  If the SFCCs send a failure message to the EIS, or the System Data 
R  Acquisition Concentrators (SDAC1 and SDAC2) (Ref. 31-54-00) send a 
R  SFCC failure message: 
R  - the white S indication changes to amber 
R  - the slat symbol changes from green to amber. 
R  B. No Data at the Data Management Computer (DMC) Input 
R  (1) No Position Data 
R 
R  When no valid position data is available for the slats at the DMC 
R  input: 
R  - the slat position symbol goes out 
R  - the white points showing the slat positions go out 
R  - two amber crosses come on at the slat side of the display 
R  - the position indication of the flap and slat control lever changes 
R  from green to cyan. 
R  (2) No Configuration Indication 
R 
R  When no valid configuration data is available from the DMC, two amber 
R  crosses replace the lever position indicator.
