The top of a black and amber strip along the speed scale indicates this speed.
It represents the speed corresponding to the angle of attack at which alpha protection
becomes active (Refer to DSC-27-20-10-20-B PROTECTIONS - HIGH ANGLE OF ATTACK
PROTECTION).
It is displayed when in pitch normal law.
(3) Alpha Max Speed
The top of a red strip along the speed scale indicates this speed. It represents the speed
corresponding to the maximum angle of attack that the aircraft can attain in pitch normal law
(Refer to DSC-27-20-10-20-B PROTECTIONS - HIGH ANGLE OF ATTACK PROTECTION).
It is displayed when in pitch normal law.
(4) VMAX
The lower end of a red and black strip along the speed scale defines this speed.
It is the lowest of the following :
• VMO or the speed corresponding to MMO
• VLE
• VFE
(Refer to PRO-SUP-10 Characteristic Speeds)
(5) Stall Warning Speed (VSW)
The top of a red and black strip along the speed scale defines this speed.
It is the speed corresponding to the stall warning. (Refer to DSC-27-20-10-20-B
PROTECTIONS - HIGH ANGLE OF ATTACK PROTECTION)
VSW information is inhibited from touchdown until 5 s after liftoff.
It is displayed when operating in pitch alternate or pitch direct law.

(1) Decision Speed : (V1)
This is a blue symbol (numeral one) that the crew inserts manually through the MCDU. When it
is off the scale, the upper part of the scale shows it in numbers.
It disappears after liftoff. (Refer to PRO-SUP-10 Other Speeds)
(2) Rotation speed : (VR)
This a blue circle and corresponds to the value that the crew inserts manually through the
MCDU. It appears during takeoff while on ground.
Note: V2 is represented by the target speed index during takeoff.
V2 is manually inserted by the crew through the MCDU.
(3) Minimum Flap Retraction Speed
This is a green symbol (letter F).
It appears when the flap selector is in position 3 or 2. (Refer to PRO-SUP-10 Characteristic
Speeds)
(4) Minimum Slat Retraction Speed
Represented by a green symbol (letter S).
It appears when flap selector is in position 1. (Refer to PRO-SUP-10 Characteristic Speeds)
(5) Green Dot (Engine-out operating speed in clean configuration)
This green dot appears when the aircraft is flying in the clean configuration.
It shows the speed corresponding to the best lift-to-drag ratio.
(6) VFE NEXT
This symbol, an amber =, shows the VFE corresponding to the next flap lever position.
It appears when the aircraft altitude is below 20 000 ft. (Refer to PRO-SUP-10 Limit Speeds)

ALTITUDE
Applicable to: ALL
GENERAL
(1) Altitude Indication
Given on a grey-colored background, both in analog and digital presentation, with the white
moving scale and the green digital readout in the altitude window.
Small white marks are positioned on the scale against the round values (e.g. 280, 290...).
“NEG” appears in the window in white for negative altitudes.
The altitude window changes from yellow to amber, if the aircraft deviates from the
FCU-selected altitude/flight level (refer to altitude alert system).
On any approach for which an MDA (MDH) is entered in the FMGS, the altitude numbers
change from green to amber, when the aircraft goes below the MDA (MDH).
(2) Target Altitude or Selected Flight Level Symbol (magenta or blue)
This symbol shows the FCU-selected altitude (if QNH, if installed, baro reference is
selected), or the selected flight level (if STD baro reference is selected), or selected height (if
QFE baro reference is selected).
When the FMGC operates in the vertical managed mode, this symbol is in magenta, if it
represents a flight plan altitude constraint that the FMGC will follow. If the target altitude or
flight level is on the scale, the symbol is displayed and the numerical value appears inside
the symbol.
If it is off the scale, the symbol is not displayed, and the numerical value appears above or
under the scale.
