Displayed on the MCDU TAKEOFF page.
V2 : Takeoff safety speed that the aircraft attains at the latest at an altitude of 35 ft
with one engine failed and maintains during the second segment of the takeoff.
Represented by the SPEED SELECT symbol on the speed scale.
Minimum value equal to 1.13 VS for the corresponding configuration.
Inserted manually through the MCDU by the crew.
Displayed on the MCDU TAKEOFF page.
VREF : Reference speed used for normal final approach.
Equal to 1.23× VS of configuration FULL.

VAPP : Final approach speed.
Displayed on MCDU APPR page.
Calculated by the FMGCs.
Represents: VAPP=VLS+wind correction.
The wind correction is limited to a minimum of 5 kt and a maximum of 15 kt.
The flight crew may modify VAPP through the MCDU.
During autoland or when A/THR is on or ‐ in case of ice accretion, or gusty
crosswind greater than 20 kt, VAPP must not be lower than VLS +5 kt.
VAPP TARGET : Represented by a magenta triangle.
Calculated by the FMGCs
Gives efficient speed guidance in approach during various windy conditions.
Represents:
VAPP TARGET=GS mini+actual headwind (measured by ADIRS)
GS mini=VAPP–TOWER WIND (headwind component along runway axis
calculated by FMGC from tower wind entered on MCDU).

CABIN TEMPERATURE CONTROL
Applicable to:
SYSTEM OPERATION
The cabin is divided into 3 temperature control zones : FWD, MID and AFT. The length of the
three zones is, as far as practicable, adapted to the individual cabin class arrangement by
respective programming of the CIDS.
The cockpit cabin temperature selector is used to select prior to flight a common cabin master
temperature for all zones.
The common master temperature can be individually adapted for the three cabin zones at any time
via the cabin temperature page of the Programming and Indication Modul (PIM) on the forward
attendant panel. An individual zone correction up to +/– 2.5 °C (4.5 °F) can be selected for the
FWD, MID or AFT cabin zones in steps of 0.5 °C (0.9 °F).

CABIN TEMPERATURE SELECTION
The system is designed to minimize flight crew workload. The cockpit and cabin selections should
be set only once prior to flight. Throughout the flight the system takes care of cabin temperature
regulation and under normal operating conditions there is no need to change the selection during
flight.
It is recommended to follow these guidelines :
Note: Any change of selection makes the system blow either colder or hotter air into the cabin
which may result in a temporary discomfort for the passengers. To reach a stabilized
cabin temperature again the system needs about 20 min : 10 min cabin temperature
adjustment plus 10 min to compensated for furniture and lining heat dissipation. After a
selection has been changed allow the cabin temperature to stabilize again before the
selection is changed again.

ON GROUND, PRIOR TO FLIGHT :
1. The cabin temperature selector in the cockpit (AIR panel) should be set to about the 10
o’clock position (21.5 °C/70.7 °F) for ground and flight operation.
2. The zone correction should be set to zero by pressing the <<RESET TO COCKPIT
SELECTED TEMP>> soft key on the cabin temperature page of the PIM.
The above settings provide a good cabin temperature comfort for most operating conditions.
