Like what you can see on Cessna
![Page 48: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/48.jpg)
The upper part of the display is known as the Flight Mode Annunciator (FMA).
![Page 49: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/49.jpg)
When below 2500 feet, a digital radio altimeter is displayed
![Page 50: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/50.jpg)
Attitude information is shown at the center of the display.
![Page 51: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/51.jpg)
The attitude indicator works in the normal sense. The aircraft is represented by 3 black and yellow symbols which remain fixed.
Just like looking the aircraft from the back
![Page 52: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/52.jpg)
There is a gradual scale for pitch angle above and below the horizon.
The yellow dot at the middle represents the lateral axis of the plane.
![Page 53: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/53.jpg)
The Sky Pointer 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.
Sky Pointer
![Page 54: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/54.jpg)
Below the roll index is the Side Slip Index. This index moves to indicate side slip and replaces the old fashioned slip ball.
Side Slip Index

The compass display is very conventional.
The gray scale moves against a fixed yellow line which represents the centerline of the aircraft.
In the example shown the aircraft is heading 091 degrees.
HEADING 091
![Page 59: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/59.jpg)
The small green diamond represents the aircraft track, and it is normally referred to as the TRACK DIAMOND.
In the example shown the track is 094 degrees which means that the aircraft has 3 degrees of drift to the right.
TRACK 094
![Page 60: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/60.jpg)
A selected heading may appear either as;
• a blue figure, on the appropriate side on the compass scale or
•a blue triangle
![Page 61: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/61.jpg)
On the FCU there is a Heading selector, with an indicator, that is linked to the selected heading indication on the PFD compass.

PFD also “teaches” us how to fly
![Page 67: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/67.jpg)
When the Flight Director pb on the EFIS control panel is selected.
Flight Director indications are on the attitude indicator
![Page 68: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/68.jpg)
A Flight Director pb on the EFIS control panel enables the pilots to switch the Flight Director display on.
Notice that there is an indication on the FMA when the Flight Directors are switched on.
![Page 69: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/69.jpg)
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.
Flight Director Roll Bar

![Page 70: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/70.jpg)
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.
Roll to the right directed
Pitch up directed
![Page 71: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/71.jpg)
The Speed scale moves behind a fixed yellow reference line and triangle. In the example shown the indicated airspeed is steady at 250 knots.
![Page 72: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/72.jpg)
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.
Speed Trend Arrow
![Page 73: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/73.jpg)
Selected Target Airspeed
Manual speed selection is achieved by a rotary selector on the FCU panel.

As a general rule on the PFD a Magenta indication means Managed and a Blue indication means selected.
Magenta = Managed Blue = Selected
![Page 75: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/75.jpg)
To look at the various other indications on the Airspeed scale we will run through a typical takeoff profile.
We will assume a departure with the Flaps in position 1+F.
![Page 76: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/76.jpg)
So it’s now your turn to take off

In the A320 family, manual roll and pitch are controlled by the side sticks.
They are spring-loaded to neutral and receive no feedback from the flight controls.
![Page 93: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/93.jpg)
Movement of one side stick will not cause movement of the other.
In this case, as the left side stick is moved, the right remains in the neutral position.
![Page 94: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/94.jpg)
FLIGHT CONTROLCOMPUTERS
A side stick sends a message to the flight control computers demanding an aircraft maneuver.
![Page 95: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/95.jpg)
FLIGHT CONTROLCOMPUTERS
CONTROL SURFACES
The flight control computers process the input and send it to the control surfaces.
and instructions called LAWS. The processing uses pre-set limitations

Normal Law is modified depending on the phase of flight. It operates in 3 modes:
Ground mode: • Operates on the ground when the aircraft is electrically and hydraulically powered. Controls are conventional.
Flight mode:• Operates in the air after a gradual transition from ground mode just after lift off to 150ft
Flare mode:• Modifies Flight Mode to introduce a conventional ‘feel’ to the landing phase.

So what is the difference between
Conventional Aircraft
and
Our beloved AIRBUS?
![Page 98: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/98.jpg)
Conventional aircraft
•Control surface deflection is directly proportional to control yoke deflection.
•The same yoke input produces a:
- Higher rate of pitch/roll at high speed,
- Lower rate of pitch /roll at low speed.
![Page 99: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/99.jpg)
A side stick deflection gives a rate demand to the Flight control computers.
For the same side stick input, the control surface deflections will be:
- Large at low speed, but- Small at high speed.
•A side stick input is a :- Rate of roll demand in roll,- Load factor (g) demand in
pitch.

So how to fly?
![Page 101: Dragonair Certificate Program Screening Flight](https://reader038.fdocuments.net/reader038/viewer/2022103111/54bc10ef4a7959f4648b4662/html5/thumbnails/101.jpg)
In flight mode, if you wish to execute a descending left turn, you set the required attitude and then return the side stick to neutral.
The neutral side stick position demands zero rates of pitch and roll.
The flight control computers will maintain the set attitude until you use the side stick to demand an attitude change.
Throughout the maneuver, there are no pilot trim inputs.

With the aircraft established on the localizer;
•the heading is 230 degrees
•the track diamond is showing 3 degrees of left drift
•The ILS front course dagger is beneath the track diamond.
You will see how useful the track diamond can be to help you fly an accurate approach in the simulator phase.
