Captain of a TransAsia Airways ATR mistakenly switched off the plane’s Engine

Taiwan’s Aviation Safety Council reported that this week’s crash ofTransAsia Airways flight 235 may have been a result of the aircraft losing power in both engines. However, only one of them failed.

“The first engine experienced a problem 37 seconds after take-off at 1,200 feet,” Aviation Safety Council director Thomas Wang told the press.

Black box data shows that the ATR-72-600 turboprop airliner’s rightengine failed, which triggered a warning in the cockpit, Deutsche Welle reported. But the aircraft’s functioning left engine was manually shut down. Wang told the media that it is “unclear” why this happened.

The pilots then attempted to restart the engine but couldn’t.

The TransAsia plane struck a bridge before crashing into a river.When an engine fails on a turboprop, such as the 9-month-old ATR involved in the crash, the propeller on that engine goes into an “auto feather” mode. This reduces drag and disturbance to aircraft – basically, enabling it to continue flying.

According to Mark, modern turboprop airliners are designed to fly on just one engine. Even in emergency situations, the technology on board the aircraft should allow the pilot to get it out of trouble, he added.

Authorities reported that of the 58 people on board the TransAsia flight, more than 30 have been killed and many more are still missing. (Source : Business Insider)

On 6 February, investigators revealed that the left engine, which does not appear to have had suffered a malfunction, had been manually shut off, while cautioning that it was “too early to say if human error was a factor”. Investigators released the following preliminary sequence of events. All times are local (UTC+8).

  • 10:51:13 — Crew receives take-off clearance
  • 10:52:34 — Tower asks crew to contact Taipei Departure
  • 10:52:38 — Right engine failure alert; master warning sounds for 3s
  • 10:53:04 — Crew reduces power to the left engine
  • 10:53:12–18 — Stall warning sounds
  • 10:53:24 — Crew cuts power to the left engine
  • 10:53:34 — Crew declares emergency: “Mayday, mayday, engine flameout”
  • 10:54:09 — Crew calls for restarting the left engine multiple times
  • 10:54:20 — Left engine is restarted
  • 10:54:34 — Master warning sounds again
  • 10:54:35 — An unidentified sound is heard
  • 10:54:36 — Recordings end

According to an initial analysis of the plane’s flight data recorders, authorities said one of the plane’s engines went idle 37 seconds after the aircraft took off from Taipei Songshan Airport. ASC authorities also said the pilot made a “mayday” call and announced a flameout 35 seconds after noticing an engine failure. However, the CAA confirmed that Taipei International Airport’s control tower did not hear the “mayday” signal.

The ASC issued an interim report on 2 July. Without assigning responsibility for the crash, the report confirmed that after the failure of one engine the pilot pulled back the wrong throttle, shutting down the other, working engine. It also said that the pilot in command, Liao Chien-tsung, failed simulator training in May 2014. The ASC is expected to publish its final report in April 2016, with a draft version in November 2015

Can Airline Seat Cushions Be Used As Life Jackets?

Can Airline Seat Cushions Be Used As Life Jackets?

In the event of an aircraft ditching into water, there’s a common question: Can aircraft seats serve as an alternative to life jackets for flotation? The answer lies in understanding their respective functions.

While seat cushions can provide some buoyancy in water, they are not intended nor certified to function as life jackets. Their primary purpose is to offer cushioning for passengers during flight. On the other hand, life jackets are meticulously engineered to keep individuals afloat in water, equipped with buoyancy materials, secure straps, and reflective elements for visibility. They offer numerous advantages over mere cushions.

While a seat cushion might offer temporary assistance in staying afloat, it’s not a dependable substitute for a proper life jacket during an emergency. It’s crucial to utilize approved safety equipment when near bodies of water. A life jacket, designed to keep a person buoyant for extended periods, offers the rigidity needed for prolonged flotation and allows for easy movement of the arms to navigate effectively.

What fabric is used in aircraft seats?


Seats are meticulously designed to fulfill multiple purposes, ensuring passenger comfort, safety, and protection from unforeseen circumstances like fires and accidents. A typical design incorporates an aluminum frame with blocks of polyurethane foam affixed to it. Additionally, a layer of fire-resistant fabric, such as Kevlar or Nomex, is often applied over this framework, topped with a layer of cloth or leather.

Leather seats, while luxurious, are more expensive compared to traditional cloth seats. The majority of fabrics used in seat upholstery contain at least 90% wool fiber, with the remainder typically consisting of polyamide (nylon). Wool stands out as the primary fiber chosen for commercial airline seating fabric due to its desirable properties and suitability for such applications.

What is the lightest economy seat?

In recent times, airlines have been downsizing seat dimensions to accommodate more passengers, resulting in reduced cushion length and leg space. This contrasts with earlier times when airlines offered more generously cushioned seats and ample amenities.

According to Recaro Seats Company, their SL3710 model represents the lightest economy class seat available, weighing in at a mere 8 kg (17.6 lb.), setting a new standard in aircraft seating.

For individuals weighing more than 350 pounds, fitting into a standard economy-class seat can be a challenge due to the narrower dimensions. Economy seats, also referred to as “coach,” “standard,” or “main cabin” seats, typically range from about 40 to 48 centimeters in width, further emphasizing the need for more accommodating seating options.
