When below 2500 feet a digital radio
altimeter is displayed.
In this module, we will concentrate on
the Primary Flight indications.
Let’s start with attitude!
EFIS MENU
PFD Presentation 11/97
Attitude information is shown at
the center of the display.
EFIS MENU
PFD Presentation 12/97
The attitude indicator works in the
normal sense. The aircraft is
represented by 3 black and yellow
symbols which remain fixed.
EFIS MENU
PFD Presentation 13/97
There is a graduated scale for
pitch angle above and below the
horizon.
EFIS MENU
PFD Presentation 14/97
Bank angle is displayed at the top
of the indicator, each graduation
represents 10 degrees angle of bank.
EFIS MENU
PFD Presentation 15/97
The Roll Index triangle moves
against a fixed scale to show angle of
bank.
To show both the pitch and bank
indications in use let’s look at the
indication for a climbing turn.

In this example the aircraft is in a
20 degree banked turn to the left with
a nose up pitch attitude of 10
degrees.

Below the roll index is the Side
Slip Index. This index moves to
indicate side slip and replaces the
old fashioned slip ball.

When the Flight Director pb on the
EFIS control panel is selected Flight
Director indications are
superimposed onto the attitude
indicator. In the example shown the
flight director is centralized.
EFIS MENU
PFD Presentation 19/97
The vertical line is the Flight
Director roll bar, while the horizontal
line is the Pitch bar.
Let’s look at an example of the
Flight Director in use.

In this example the flight director
is directing a pitch up and roll to the
right. Once the aircraft has achieved
the required pitch and bank the
Flight Director bars will once again
be centralized.
Now let’s look at the airspeed
indications on the PFD.

The Speed scale moves behind a
fixed yellow reference line and
triangle. In the example shown the
indicated airspeed is steady at 250
knots.
EFIS MENU
PFD Presentation 23/97
When the aircraft is accelerating,
or decelerating a Speed Trend Arrow
appears. This arrow shows the value
that will be attained in 10 seconds if
the acceleration remains constant. In
the example shown the aircraft will
decelerate to 240 knots in 10
seconds. The use of the speed trend
arrow will be demonstrated during
your simulator training.

When the Flight Management and
Guidance System, FMGS, is
controlling the airspeed a magenta
Target Airspeed triangle appears.
This is normally referred to as the
Managed speed. In the example
shown the Managed target airspeed
is 240 knots and the aircraft is
decelerating towards that speed.

If the target airspeed is selected
manually a blue triangle appears.
This is normally referred to as
Selected Speed. In the example
shown a Selected airspeed of 260
knots has been set and the aircraft is
accelerating towards it.

Manual speed selection is
achieved by a rotary selector on the
FCU panel. Just above the selector
is the indication of the selected
speed.

PFD Presentation 27/97
As a general rule on the
PFD a Magenta indication
means Managed and a Blue
indication means selected.
You will see this in the
examples that follow.
