Flight Simulator?
TOO EXCITED
Everyone here will be invited to Cathay City
and fly a real Dragonair A320 Simulator!
Before that, it’s your good friend !
You will learn how to fly the Airbus A320
NOT FREE FALL
Follow mentor’s instruction
When you get into the sim
Mind you head!
NOT TO TOUCH anything you shouldn’t
touch
Then you will be asked to fly a certain pattern one
by one
From 25L to TD
Then ILS 25R approach
No pushback and startup needed
Before that you should know what is going on
Except A300 family, all airbus cockpits look
like this
This is overhead panel
You don’t have to touch it
Pedestal
Throttle, Flaps, Spoilers and MCDU
Here is EFIS
Electronic Flight Instrument system
Outdated
After you have adjusted your seat, your mentor will let
you
TAXI
The 4x EFIS displays provide the pilots with Flight data to help them operate the aircraft in a safe and efficient way
Flight parameters are displayed on
Primary Flight Displays ( PFD )
while navigation data is displayed on Navigation Displays( ND )
ELECTRONIC FLIGHT INSTRUMENT SYSTEM

So look at the right seat
Primary Flight Display
NavigationDisplay
Flight parameters are displayed on
Primary Flight Displays ( PFD )
while navigation data is displayed on Navigation Displays( ND )
We’ll talk about ND
The ND, can present the pilots with a lot of useful data
ND gives the pilots a visual presentation of where the aircraft is in relation to Airfields, Navaids, etc, the operation of the aircraft is also made easier
The Ground Speed (GS) + True Air Speed (TAS) are permanently displayed on the top left cornerGround Speed
True Air Speed
Below the speed indications, the wind data are presented; wind direction (true north), wind speed and an arrow to indicate the wind direction with respect to magnetic north.
Here, wind from 60 degrees at 52 kt.
Step on your brake pedal to release parking brake
No speeding on taxiway
On 90 degrees turn
You will start at “holding point J11”
Then get into runway
25L
So how about our beloved
PFD?
use PFD later when takeoff
(Video)
The plane is on runway!
Flight parameters are displayed on Primary Flight Displays (PFD)
and intergraded few tradition component into one DU
ELECTRONIC FLIGHT INSTRUMENT SYSTEM
Primary Flight Display
The Artificial Horizon is in MIDDLE
Air Speed Indicator on the left
Altimeter tape on the right
Also the Vertical Speed Indicator
The Primary Flight display, displays all the normal Primary Flight indications.
•Attitude,•Airspeed,•Altitude,•Vertical Speed,•Heading and Track
Indicators are laid out in a
classic instrument
“T” configuration.
Like what you can see on GAs
The upper part of the display is known as the
Flight Mode Annunciator (FMA)
When below 2500 feet, a digital
radio altimeter (RA)
is displayed
Attitude information is shown at the center of the display
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
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
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
In this example the aircraft is in a 20 degree banked turn to the left with a nose up pitch attitude of 10 degrees
30 degrees of left bank
10 degrees of Nose up pitch
20 degrees of left bank
10 degrees of left bank
Take a look onthe bottom
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
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
A selected heading may appear either as;
• a blue figure, on the appropriate side on the compass scale or
•a blue triangle
On the FCU there is a Heading selector, with an indicator, that is linked to the selected heading indication on the PFD compass
Target HeadingSelector and
Indicator
All the indications associated with Altitude are located on the right hand side of the PFD
CLB NAV
The main part of the display is dedicated to the Altimeter. To the far right is the Vertical Speed display

FL 70
In the final stage of an approach the ground reference ribbon will reappear along with a landing elevation line
30.08QNH

The vertical speed indication is showing a rate of decent of 800 feet/ minute
Also notice that the missed approach altitude has been set at 9000 feet.

PFD also “teaches” us how to fly
When the Flight Director pb on the EFIS control panel is selected
Flight Director indications are on the attitude indicator
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
Vertical = Roll Bar
Horizontal line =Pitch Bar
Flight Director Roll Bar
Flight Director Pitch bar
In this example the FD 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 centralised
Now let’s look at the airspeed indications on the PFD
Roll to the right directed
Pitch up directed
The Speed scale moves behind a fixed yellow reference line and triangle. In the example shown the indicated airspeed is steady at 250 knots
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 ac( de ) celeration remains constant
Speed Trend Arrow
Selected Target Airspeed
Manual speed selection is achieved by a rotary selector on the FCU panel
Speed Selector and Indication
Magenta indication means Managed
Blue indication means selected
Magenta = Managed Blue = Selected
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
So it’s now your turn to take off
Lower down the flaps
Give it some POWER!

During the take off roll a blue decision speed, V1, and a magenta V2 speed are shown
Notice that since these speeds are beyond the visible scale they are shown as numbers
Decision speed (V1) of 134 knots
V2 speed of 151 knots

It seems that something is missing
Oh yes…
How to drive an Airbus
No… we have neither a steering wheel
nor a control column
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
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
FLIGHT CONTROLCOMPUTERS
A side stick sends a message to the flight
control computers demanding an aircraft
maneuver
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
Ground mode
Ground mode
Flight mode
Flare mode
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?
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.
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.
Fly by wire aircraft
So how to fly?
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
Take the box to the cross
Put the center of F/D into the square
The airbus also provides some
protections
• Pitch attitude protection
•30 degree up / 15 degree down
Pitch up limit
Pitch down limit
• High angle of attack protection
• High speed protection
Bank angle protection
No more than 67 degrees
So how to get back the
plane?
Each side stick is fitted with a red autopilot disconnect
By pressing it, a pilot disconnects the autopilot
Press twice to cancel audible warning

Audio warning – red SIDE STICK PRIORITY arrow
in front of the F/O indicating that his side stick is inoperative.
The arrow points left showing that the Captain has control.
Never trigger thisor
You will FAIL!
During the flight, your mentor will switch
different FCU settings
So what is FCU?
Here we call “Glare Shield”
In the middle of the glare shield, there is a Flight Control Unit
The FCU is one of the interface units between the pilots and the Autoflight system
There are selectors on the FCU which will affect the indications seen on the PFD and ND
The selectors, with associated indication, are provided for:
•Speed,•Heading,•Altitude.
You will see how these selectors affect the EFIS displays in the modules that follow.
SPEED HEADING ALTITUDE
Your mentor will engage A/P once you have finished
your turn
Your mentor will also do some time
keeping work
The two CHRONO pushbutton located on the glare shield, control the associated chronometer display on the individual ND
When he set heading to the left,
you fly left
When he set heading to the right, you fly
right
When he set climb, you climb
Target AltitudeSelector and Indication
1000017000 Target Altitude
Constraint altitude and target box
As the constraint Altitude is approached it appears on the scale with a target box
The aircraft is now cruising at Flight Level 370
Notice that the target Flight level box is in the middle of the scale and the vertical speed indication is at zero

When he set descend,
you descend
He jumps, you jump
(Video)
Then it’s time to get back onto the
ground
Descending!
ILS approach
What is ILS?
Instrument Landing System
divided into two system – Localizer and Glideslope
= Horizontal guidance + Vertical guidance respectively
Glideslope (G/S) – An array for Vertical Guidance
3 degrees Glide path in Hong Kong
The ILS pb on the EFIS control panel enables the pilots to switch on an ILS display
The ILS display includes indications for:
•Localizer,
•Front course,
•Glide slope,
•Information
ILS deviation information is displayed in the form of Localizer and Glideslope deviation scales
The ILS front course will be displayed in magenta at the side of the compass scale if the figure is outside the visible scale
A magenta diamond represents the localizer
When the ILS front course is within the compass scale it is displayed as a magenta dagger
In the example shown the aircraft is established on the localizer and the Glideslope indication has appeared in the form of a magenta diamond
The aircraft is now fully established on the ILS approach
Let’s look at the indications on the compass scale in detail
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

During an FMGS computed (managed) descent the single triangle is split into two to give a speed range.
A double magenta bar indicates the target speed. In the example shown the target speed is 325 knots. The speed will vary in between the two speed range indicators as the aircraft maintains the required descent profile
Managed descent profiles will be studied in depth in the Autoflight modules

Following initial deceleration to 250 knots there is an indication of the next flap limiting speed, VFE Next
In this case the next flap setting is 1 so an indication is shown at 230 knots. The VFE Next indication will be visible provided the aircraft is below 15,000 feet
Green Dot Speed may also be visible
