Once the aircraft lands all
additional speed indications are
removed apart from the speed trend
arrow.
Having thoroughly studied the
Airspeed indications lets look at
Altitude indications.

All the indications associated with
Altitude are located on the right hand
side of the PFD.

The main part of the display
is dedicated to the Altimeter.
To the far right is the Vertical
Speed display. We will look at
the altimeter indications first.

The middle part of the
altimeter contains a green
digital readout of altitude.

The red ribbon to the right
of the altitude scale represents
the field elevation. The ribbon
is currently level with the
center of the scale.

On the FCU is an Altitude
Selector with an indication of
the selected Target Altitude.

Baro Reference. In the example
shown, the QNH is 30.08
inches.

To look at the various other indications on
the Altitude and Vertical Speed scales we will
run through a typical flight profile.

The aircraft is on the ground
just prior to take off. Notice
that with the QNH of 29.92 set
the altitude indication is 10
feet.

If there is an altitude
constraint set in the FMGS
then this will be shown by a
magenta target altitude. In the
example shown the constraint
altitude is 5000 feet.

that the vertical speed
indication is showing a climb
of 3400 feet per minute.

Once past the constraint the
aircraft can be climbed further
so a new target altitude is
selected on the FCU.
