SQ0006 Crash by Dionne
Crash of SQ0006 by Vivek
- Bad Weather Conditions
- Airport Control Tower having a lack of equipment
- Carelessness of the pilots
- Money driven
05 English Assignment (Grace Tan Soo Woon)
1. Horrible Weather Conditions
The "tropical storm Xangsan, which had caused devastation across the Philippines, was approaching Taiwan" at that time, causing "winds of up to 144kph" as well as heavy rain which lead to poor visibility. This cause have contributed to the pilots' misconception of which runway they were using and could have thus went onto the wrong runway, resulting in the accident.
2. Not cordoning the runway under construction
The "disused strip at Taipei had not been completely blocked off because it was frequently used for taxi-ing aircraft", which was against the International airport regulations that stated the requirement of a runway currently undergoing repair to be cordoned off. The airport only erected a concrete block barrier "1,000 metres down the runway at the beginning of the construction zone and marked with a light." There was heavy rain that day, and the light and barrier may not have been easily visible to the pilot, so he might have thought the runway was free for use due to the airport not cordoning off the runway, so it may not have been the pilots' fault but rather the lack of following regulations that lead to the accident.
3. Possible lack of lighting on the runways
CAA spokesman Kay Yong said that "the centre lights—green on the closed runway and white on the active one—were on." However, the passage also states that "investigators have yet to determine whether the 'edge lights' running along the sides of the closed runway were on or off." The passage also continues with stating another statement from Mr Yong, "If the lights on the runway were not on, then the runway would not have looked like a runway". If the side lights were really off, the pilots are not at fault for accidentally crashing the plane into the construction and concrete barrier, as they not only could not see clearly int he horrible weather conditions, they also could not make out which runway was which.
"According to San Francisco-based attorney Gerald Sterns, who specializes in representing air crash victims' families, under such conditions the control tower should have warned the pilots by radio about the closed runway. 'The 'black box cockpit recorder indicated that wasn't done with the Singapore Airlines flight,'" This shows that there is no notification what so ever on the construction site on the runway close to the one the pilots were supposed to use, so the pilots cannot be blamed for not knowing the existence of the road block and be wary of it before crashing the plane into the barrier.
The passage also states "The airport is not equipped with ground radar so the control tower could not visually check if the plane was on the correct runway." In addition, "visibility was too low to physically see the jet from the tower", so in this case, the tower had no visuals on the plane and its movements, and are unable to warn the pilots on where they are heading to or whether they were going to crash into the construction barriers, so the pilots, not knowing about the construction and where they were heading to cannot be blamed from driving the plane straight into the barrier erected 1,000m along the runway.

Reasons for the crash
- Bad weather conditions : Tropical storm Xangsan was approaching Taiwan, with winds up to 144kph and heavy rain. This caused poor visibility
- Low visibility : It was caused by the bad weather conditions and could have led to the pilots being unable to see the lights on the barrier of concrete blocks on the closed runway.
- Unused runway under repair was not completely cordoned off : It was frequently used for taxi-ing aircraft and also to prevent serious delays for planes lining up for departure.
- Airport not sufficiently equipped : Lacked a ground radar so the control tower could not visually check if the plane was on the right runway, the one not under repair, due to low visibility.
- Lack of communication with the pilots : The 'black box' cockpit recorder indicated that the control tower did not warn the pilots about the closed runway.
Were the pilots at fault?
I think the pilots were partially at fault. This is because I feel that although they are put under pressure to meet deadlines, they should have been more conscious of the safety aspect of the flight. Furthermore, since they had the decision whether to take off or not, they probably should have delayed the flight rather than attempt it.

20_SIA Accident
- The aircraft attempted to take off under typhoon conditions
Wind speed of 144 kph(~78knots), visibility of below 500-600 metres, at night. This would make keeping on the center line of the runway difficult, and the visibility meant that it would be difficult to see the lights of the runway.
- It was taking off from a runway that had been closed for repair. The runway was thus occupied by construction machines, being obstacles for the accelerating plane.
- The intended runway was near the runway under repair and the two had almost the same identification numbers. The disused strip was not blocked off because it was used for taxiing aircraft. This would create much confusion as the pilots would not be sure if it was the correct runway, which may also be deadly under normal circumstances if the runway was also used by another aircraft.
- The control tower was not equipped with ground radar and, due to the poor visibility, could not see if the aircraft was on the correct runway. Thus did not allow the control tower to warn them if they were on the wrong runway.
- The pilots were also under pressure from their airline to avoid costly delays. This may gave influenced the pilot's decision to continue the flight.
Opinion:
I think that the pilots shoulder some responsibility for the accident, but part of the blame also goes to the airport staff. If the flight crew had been provided with the correct information about the weather, the flight would have been cancelled. The control tower staff should really have warned the pilots about the disused runway because of its close proximity to the intended one, and if the correct runway was used the plane would have taken off safely, as this particular crash was caused by it hitting the concrete blocks and construction equipment. Since other carriers cancelled their flights, it can be taken that it was the pilot's decision to continue, since the airport authorities did not intervene.
Note: Yes, it is possible to take a 747-400 off the ground under these conditions(Tried in X-plane 9 Demo.) You might want to get an airsick bag ready though, and be thankful you weren't flying an landing into the airport.

- Attempting to take off in typhoon conditions. "Los Angeles-bound flight had attempted to take off in typhoon conditions". This caused poor visibility, which lead to the next point.
- The intended runway was near one under repair which also had almost identical identifications numbers. "The intended runway was near the one under repair and the two had almost identical identification numbers, adding to the chance of confusion." Thus with poor visibility, it was easy to go to the wrong runway.
- Pilot error: They were under pressure to comply to the schedule and avoid expensive delays thus decided to take off. "Obviously pilots are under pressure from airlines to maintain tight schedules and avoid costly delays."
- Taipei not following regulations: By disobeying the International airport regulations, they did not cordon off the runway under repair, as it would create delays for planes lining up for departure. "International airport regulations require a runway under repair to be cordoned off." By disobeying the Boeing's guideline, they took off when the crosswinds was high, and made a false claim of figures. "Singapore Airlines follows Boeing's guideline of allowing takeoffs if crosswinds are lower than 55.2 kph. The airline claims that crosswinds were blowing at no more than 27.2 kph... crosswinds had reached more than 88 kph"
- Ground radar was not equipped in the airport (As it was expensive), thus the control tower could not visually confirm if the plane was on the right runway. "The airport is not equipped with ground radar so the control tower could not visually check if the plane was on the correct runway."
Thus the plane struck a metre-high concrete barrier and some construction equipment, splitting the plane into three pieces and causing many deaths.
