(CP), a Senior Purser (SP), a Supernumerary In-flight Service
Manager who was on board to observe the standards of cabin
service of the flight, and nine other cabin attendants. They had
been provided with adequate rest prior to the flight. Their Annual
Emergency Procedures training and Smoke and Fire Drills were
valid. Additionally, a riding engineer, who performed ground
engineering duties at Kota Kinabalu, was on board.

1.6.2. Maintenance History
The last major maintenance was a combination of 2C and 4A
Checks that were carried out in December 2002. Special
maintenance work on the aircraft had been carried out in June 2003
for pylon modification with both engines removed and the
completion of Armoured Cockpit Door Modification, after which,
it had a sample airworthiness flight test on 5 June 2003 flown with
no significant defects found. Prior to departure from Hong Kong
on 18 July 2003, several minor Acceptable Deferred Defects of
little technical significance were noted in the aircraft maintenance
record.

1.6.3. Aircraft Weight and Centre of Gravity
Maximum Take-Off Weight
Authorized
: 205,000 kg
Aircraft Take-Off Weight : 173,668 kg
Maximum Landing Weight Authorized : 177,000 kg
Aircraft Landing Weight : 159,068 kg
Aircraft Centre of Gravity (on take-off) : 25.5% Mean
Aerodynamic Chord
(MAC)
The load sheet showed that the aircraft was within the authorized
weight limits for take-off and landing, and the centre of gravity was
within the authorized limits.
1.6.4. Weather Radar
1.6.4.1. The aircraft is equipped with a Honeywell RDR-4B
X-band weather radar, which operates at an extremely
high frequency of 9,345 Megahertz (MHz) and a very
short wavelength of 3.2 cm. Liquid water in the forms
of water droplets, water covered ice, or super-cooled
water droplets are highly radar reflective to such a
frequency. The antenna assembly produces a forwardscanning
radio beam that searches for weather by
emitting electronic energy pulses into the atmosphere
ahead of the aircraft and measures the reflected energy.
The weather radar system also provides a 180º monitor
13
that displays information on weather and turbulence as
images on the Navigation Display (ND) in the cockpit.
Depending on the amount of liquid water present, which
is related to the level of precipitation, different colours
are displayed on the ND.
1.6.4.2. Weather targets detected are colour-coded based on the
intensity of the radar signal return. The table below
shows how the display colour coding correlates to the
approximate intensity of rainfall as given in the
Honeywell RDR-4B Forward Looking Windshear/
