Airline pilots in Japan are unaware of a cabin fire until the crew informs them

Pilots of a Japanese airliner that collided with a smaller plane at Tokyo Haneda Airport were initially unaware that their jet was on fire, Azernews reports citing to BBC.

After which, the evacuation of all 379 on board Japan Airlines Flight 516 proceeded with life-saving precision.

Five of six people on board the smaller coastguard plane, a Bombardier Dash-8, died.

"Right after the plane touched down, the pilot felt a sudden shock, and lost control to stay in the runway. A fire took place but the pilots didn't recognise it in the beginning and learned about it [through the] cabin attendant," the JAL spokesperson said.

There were three pilots and 12 flight attendants on board when the incident took place. The aircraft's announcement system was damaged, leaving the crew to use megaphones and their own voices to shout instructions.

"The first thing cabin attendants did [after they realised there were] passengers who recognised that their plane was on fire, was to make them stay calm and not to stand up, which could make the escape very difficult. The announcement system was unusable so these instructions were made without it."

Japanese media have described the evacuation as a "miraculous 18 minutes". Passengers left their hand luggage, dashed to emergency exits and slid out of the aircraft before it was engulfed in flames.

"[As] smoke started to come into the cabin and spread out... cabin attendants [began shouting] at passengers, [saying]: 'Leave your belongings!', 'Take off your high heels', and 'Head down'," said the spokesperson.

Their "co-operation... was [the] key for all passengers [being able] to escape quickly and safely", they added.

Japanese authorities said late on Wednesday that the coastguard plane was not cleared for take-off on Haneda's runway. The plane was scheduled to deliver relief supplies to earthquake-hit areas.

The airline pilots reported feeling a strong impact after landing, indicating the moment of collision on Tuesday evening, the reports quoted a statement from Japan Airlines as saying. They said their Airbus A350 also veered to the right side of the runway.

The pilots also reported that they had no visual contact with the coastguard plane, so they did not discuss aborting their landing, the reports added.

The well-drilled scenes on the Japan Airlines plane contrast starkly with aircraft evacuations that fail to strictly adhere to safety protocols.

Incident is the first major accident involving an Airbus A350, one of a new breed of aircraft built largely of advanced materials such as carbon fibre-reinforced plastic. The aircraft manufacturer is sending a team of specialists to assist in the investigation of the Japan Transport Safety Board.
