Volcanic ash prompts AirNav to monitor airspace and update closures at three Indonesian airports

AirNav Indonesia is closely monitoring the spread of volcanic ash from Anak Krakatau as the changing conditions affect airspace and temporarily close three airports.

The national air navigation provider said the ash plume’s shifting conditions require continual updates to aviation information and navigation services. Monitoring is being conducted through the Indonesia Network Management Center to support air-traffic management and deliver timely safety information.

AirNav issued and updated NOTAMs covering temporary closures at Halim Perdanakusuma, Soekarno-Hatta International and Radin Inten II airports. Soekarno-Hatta airspace closed at 4:52 a.m. local time and was expected to reopen at 9:30 a.m. Radin Inten II closed at 4:18 a.m., with reopening estimated for 8 a.m., while Halim Perdanakusuma closed at 7:20 a.m. and was expected to reopen at 10 a.m.

“Every change in conditions that could affect flight safety is immediately followed up through updated aeronautical information and adjustments to air navigation services as needed,” AirNav corporate secretary Hermana Soegijantoro said.

AirNav said it was coordinating with aviation stakeholders and would continue updating aeronautical information as the ash spread developed. It said flight safety remained the priority.
