AIRASIA INDONESIA QZ8501
1. Indonesia AirAsia QZ8501/AWQ8501 scheduled to arrived at
Changi Airport singapore from Juanda International Airport surabaya, Indonesia
at 8:30 a.m on 28th December 2014.
2. Manufactured by Airbus,A320-216, with registration number
PK-AXC person on board (p.o.b) 155 passengers and seven crews on board.
3. Bad weather become the prime suspect for bring down
airasia QZ8501.
4. The pilots requested to divert the plane from originated
flight plan to avoid clouds (cumulonimbus cloud).
CUMULONIMBUS CLOUD (CB)
5. The cumulonimbus cloud is the worst enemy for the pilots
to deal with. The pilots taught to avoid this kind of cloud in any
circumstances.
6. The cumulonimbus cloud not only brings heavy precipitation
but there are another harmful causes that can bring the QZ8501 down such as
lightning, icing condition, turbulence and unstable upward and downward air flow.
These combination is the best recipe to bring QZ8501 down.
7. The pilots requested to divert to the left and climb from
FL320 (32000 ft) to FL380 (38000 ft). The official report from indonesia meteorological
agency told that some of the cumulonimbus clouds on that day rising to a height
of nearly 45000 ft had been observed in the plane's route. There is the chance
for the QZ8501 to meet by the clouds.
8. Heavy precipitation does not give the main cause to bring
down the plane, the visibility for the pilots just decrease.In the modern world
of aircraft, that is not the big problem, big commercial aircraft such as
Airbus A320-216 with sophisticated instrument the pilots not only depend on
Visual Flying Rules (VFR) only and can rely on the instruments to aviate and
navigate the plane (IFR).
9. Lightning from the cumulonimbus may be have a responsibility
to bring down QZ8501, the current from lightning can interupt instruments attch
in the cockpit or not. But the pilots can still cope with this situation
because not all instruments are from electrical based there are also gyroscopic
based instruments.In nowadays designation of modern aircraft, the body of the
aircraft can resist when the lightning struck and earthing the current
harmlessly.
