QZ8501 is just one of many other flights moving in the same area with bad weather conditions on December 28.

So why only QZ8501 has trouble?

News reported that the pilot of QZ8501 had asked to change the flight direction to avoid bad weather, but the air station staff did not approve to avoid colliding with other aircraft in the area.

The QZ8501 also encountered another disadvantage when the station not in Jakarta took 30 minutes to issue a notice about the loss of connection with QZ8501 to Singapore. After that, it took several hours for the authorities to conduct a search, mainly due to bad weather.

Australia's aviation security specialist, Mr. Des Ross, said the pilots on the QZ8501 did not signal emergency because they were focusing on controlling the aircraft.'The pilot's top priority is to fly the plane and ensure safety for everyone on it. It is also possible, they have a short-circuit problem and a broken radio , 'Mr. Des said.

However, aviation experts find it difficult to understand the details of the emergency navigation device signal, which was originally designed to automatically transmit the coordinates of an aircraft in the event of an accident, but does not transmit effect in the case of QZ8501.'These small navigation devices are often very reliable, but we still have no information about them now,' Mr. Ross said.

Meanwhile, the director of Indonesia Traffic Safety Committee Tatang Kurniadi knows that the device may be damaged or the plane may have crashed into the mountain, causing the signal to be blocked.
