Airport's radar on the blink again
Airport's radar on the blink again

Around 15 hours after the radar came back online, another radar
breakdown affected air traffic control at the country's main
airport, Soekarno-Hatta International Airport, west of Jakarta,
on Friday morning.
The second incident delayed 113 flights for over seven hours
and left thousands of passengers stranded at the airport.
Airport operator PT Angkasa Pura head Risman Nuryadin said
that the breakdown was unusual as even the back-up system had
failed.
"We're still trying to find the answer," he said. "Why did it
happen during peak hour when about 700 flights were trying to
take-off or land."
The National Air Carriers Association (INACA) economic
commission head Jaka Pudjiono echoed Risman's statement on the
failure of the back-up system.
Risman said the airport operator had started to upgrade all
computer systems in 1997 and completed the process two years
later. The airport's main data computer and its back-up are
connected with the radar to enable air traffic controllers access
to key flight data.
Since Thursday's breakdown from 12:50 p.m. to 3 p.m., the main
data computer has not worked as normal. On Friday, it broke down
again from 8:10 a.m. to 3 p.m.
The incident forced some flights to be rerouted to Halim
Perdanakusumah air base in East Jakarta, including an airplane
carrying the People's Consultative Assembly speaker Amien Rais,
who had just returned from campaigning for the People's Mandate
Party (PAN).
From about 3 p.m., officers resorted to a manual air traffic
control system and were able to direct 90 airplanes in take-off.
The remaining 23 airplanes were forced to wait due to the
breakdown.
"The radar functioned normally but it could not deliver
information on flights to the main data computer due to the
computer's malfunction," said airport operator PT Angkasa Pura
spokesman Wasfan.
He added that the cause of the damage to the eight-year-old
computer system was under investigation. He pointed out that the
breakdown had nothing to do with bad weather and heavy rain.
Head of public relations and international affairs for the
Ministry of Communications, Mochammad Syukur, said that the
system failure was possibly due to the age of the computers.
He added that the government should urge the airport's
management to replace the existing computers.
A passenger of national carrier Garuda Indonesia, Suyoto, who
had arrived from Denpasar, Bali, in the afternoon, complained
that the plane had hovered above the airport for more than 30
minutes before landing.
"It's my first such experience and I hope it will never happen
to me again," he said, rushing to attend a business meeting.
