accurately .
NAVIGATION MENU

There are no radio altimeter controls in the
cockpit. Both radio altimeters come on
automatically when AC power is applied to the
aircraft.

After a brief self test, the radio altimeters are in
a standby mode during ground operations. They
become active at lift-off and then operate
continuously until touchdown.

Radio height is always expressed as the number of
feet between the bottom of the wheels and ground.
Radio Altimeter data is supplied to several
different users and is displayed on both PFD at all
times below 2500 feet AGL.

This color coded digital readout is coupled with a
white ground indication line and a red ground ribbon
on the Altimeter scale.
NAVIGATION MENU
Radio alti presentation 12/17
The ground indication line and the red ground
ribbon correspond to the raising ground level when
the aircraft is descending.
NAVIGATION MENU
Radio alti presentation 13/17
As the aircraft descends below approximately 500
feet AGL the red ribbon appears at the bottom of the
altimeter scale and begins to move up.
NAVIGATION MENU
Radio alti presentation 14/17
The white ground line moves from the bottom of
the PFD towards the horizon.
NAVIGATION MENU
Radio alti presentation 15/17
At touchdown, the ribbon is in the centre of the
altitude readout and the white ground line is merged
with the horizon, as shown. These are designed to be
used as a ground reference during autoland
operations.
NAVIGATION MENU
Radio alti presentation 16/17
In addition to the visual indications, during
approach, there is a synthetic voice for radio height
announcement.
NAVIGATION MENU
Radio alti presentation 17/17
Depending on individual airline requirements, auto
call-out announcements are made at pre-determined
radio-altimeter heights.
Example, “FOUR HUNDRED” at four hundred feet
radio altitude.
These call-outs will be heard even if the loudspeakers
are turned off.

Definitive text :
At pre-determined heights, the announcement will
be heard through the loudspeakers, even when the

For example, at four hundred feet, a call out of
“FOUR HUNDRED” is made.
