CARE – Charity for Aviation Recreation and Education

Collaborated with

Hong Kong Air Cadet Corps+ Sea Cadets+Scout Association of Hong Kong

to provide different aviation knowledge courses since 2009

CARE – Charity for Aviation Recreation and Education

We also visited and established a connection with the UK based Anglian Flight Centres in 2015

Outstanding students who completed the 60-week-course at CARE will be recommended to

Anglian Flight Centres

for participating self-funded private pilot programme

Electronic Flight Information System

Primary Flight Display (PFD)

& Navigation Display (ND)

Flight parameters are displayed on

Primary Flight Displays （ PFD ） while navigation data is

displayed on Navigation Displays（ ND ）

ND has several modes

In ARC mode,• Aircraft Position• Navaids• Airfields• TCAS(Traffic

“MAN FLEX 55, SRS, RUNWAY, AUTO THRUST BLUE”

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

Radio Altimeter (RA) • Activated

below 2500 feet above ground

The fixed black and yellow symbols represents the aircraft

Read attitude information:• Imagine looking the

aircraft from the back• Sky is BLUE• Ground is BROWN

The Sky Pointer

Moves to show angle of bank

Always points to the sky

The fixed black and yellow symbols represents the aircraft

The fixed black and yellow symbols represents the aircraft

The gray compass 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

TRACK DIAMONDSmall green diamond

represents the aircraft track

In the example shown the track is 094 degrees which means that the aircraft has 3 degrees of drift to the right

TRACK 094

The main part of the display is dedicated to the Altimeter. To the far right is the Vertical Speed display

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

Ground Reference Ribbon

Landing Elevation Line

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

However, if Auto Thrust is engaged, you won’t need to move the thrust lever to control the speed

In the assessment Auto Thrust is engaged for you.

Localiser indicator indicates the aircraft’s horizontal position relative to the centreline of the runway

Glideslope indicator indicates the aircraft’s vertical position relative to a 3 degrees profile to the runway

Notice that the approach speed target, V Approach, has now appeared as a magenta triangle

The aircraft will continue decelerating towards F speed

By reducing towards F speed the aircraft will be below the VFE for the next flap setting
