Airspeed Failure Indications
When a parameter is unavailable (NCD), it is replaced by a flag.
For a given DMC, if the onside FAC is faulty, the speed limit
indications are taken from the offside FAC.

(9) The table below gives the conditions of display of the speed information:
-------------------------------------------------------------------------------| PARAMETERS | DISPLAY | |--------------------|--------------------------------------------------------| | Speed reference | - Two fixed yellow dashes linked together by a thin | | | yellow line and completed with a yellow triangle | | | when computer airspeed is valid,or on the ground | | | when computer airspeed is NCD. | |--------------------|--------------------------------------------------------| | Speed scale | - White when Vc is valid and more than 30 knots. | | | - Partially displayed when Vc is between 30 knots and | | | 72 knots. | |--------------------|--------------------------------------------------------| | Vsw (Stall warning)| - Vsw value indicated by the top of a red and black | | | stripe if computed airspeed and Vsw are valid and | | | (computed airspeed - Vsw) > 42kts, and pitch law is | | | no longer available. | |--------------------|--------------------------------------------------------| | Vaprot | - Indicated by the top of an amber and black stripe if | | | computed airspeed and Vaprot given by FAC are valid | | | and (computed airspeed - Vaprot) < 42kts, under | | | pitch law. | |--------------------|--------------------------------------------------------| | Valim | - Indicated by the top of a red stripe if computed | | | airspeed and Valim given by FAC are valid and | | | (computed airspeed - Valim) > 42kts under pitch law. | |--------------------|--------------------------------------------------------| | Vls | - Indicated by the top of an amber tape if computed | | | airspeed and Vls given by FAC are valid and | | | (computed airspeed - Vls) > 42kts, and Vc valid. | |--------------------|--------------------------------------------------------| | V1 | - Cyan 1 figure and mark across the Vc scale on the | | | ground if V1 given by FMGC is valid and computed | | | airspeed ok and V1 is between (Vc - 42kts) and | | | (Vc + 42kts). | | | - If V1 is above Vc + 42kts, cyan digits above the | | | speed scale. | |--------------------|--------------------------------------------------------| | V3 | - Green F when V3 and computed airspeed are valid and | | | V3 is between (Vc - 42kts) and (Vc + 42kts) and Vc | | | valid. | |--------------------|--------------------------------------------------------|
R 1EFF : 001-049, 051-099, 101-105, 151-199, 1 31-64-00Page A45 1201-299, 301-302, 1May 01/05 1 1 1CES 1 -------------------------------------------------------------------------------| PARAMETERS | DISPLAY | |--------------------|--------------------------------------------------------| |V4 | - Green S when V4 and computed airspeed are valid and | | | V4 is between (Vc - 42kts) and (Vc + 42kts) and Vc | | | valid. | |--------------------|--------------------------------------------------------| | Vfe next | - Two amber lines inside speed scale when Vfen | | | computed by FAC is valid and between (Vc - 42kts) | | | and (Vc + 42kts), and Vc valid. | |--------------------|--------------------------------------------------------| | Vman | - Green dots when Vman and computed airspeed are valid | | | and Vman is between (Vc - 42kts) and (Vc + 42kts), | | | and Vc valid. | |--------------------|--------------------------------------------------------| | Vc trend | - Yellow arrow when computed airspeed and Vc trend are | | | valid. | |--------------------|--------------------------------------------------------| | Selected speed | - Cyan triangle when selected speed is valid and | | | between (Vc - 42kts) and (Vc + 42kts), and there is | | | no ECON mode and no constraint. | | | - If speed is constrained, the cyan triangle becomes | | | magenta. | | | - If selected speed is not between (Vc - 42kts) and | | | (Vc + 42kts), cyan or magenta digits above or below | | | speed scale according to the sign of the difference | | | (Vsel - Vc). |
R **ON A/C ALL
| Selected speed | - In ECON mode, high speed margin and low speed margin | | margin | magenta when both of them and Vc are valid. To be | | | displayed each margin must be between (Vc - 42kts) | | | and (Vc + 42kts). |
