International flights to Accra could be suspended if dry, dusty weather conditions continue to block visibility.

That is the assessment of the Harmattan situation by the Ghana Civil Aviation Authority (GCAA).

The development has resulted in some domestic carriers halting operations until the situation improves.

Director of the Civil Aviation Authority, Simon Allotey, told Joy News’ Ertonam Sey instrument landing systems have been installed at selected airports to improve visibility of aircrafts approaching the runway.

An instrument landing system provides precision lateral and vertical guidance to an aircraft approaching and landing on a runway, using a combination of radio signals and, in many cases, high-intensity lighting arrays to enable a safe landing.

“We just completed installation of one unit at Kumasi [airport] but it has to go through calibration to properly get the instrument working,” Simon Allotey said.

 He said although the GCAA is proactively taking steps to improve safety at airports across the country as the dusty Harmattan persist, flights to Accra from abroad could be suspended.

Meanwhile Ghana Meteorological Agency, says the current weather conditions could get worse in the coming days.

The Agency has predicted December 13 as a possible date for ease in Harmattan conditions.

The cold, dry and dusty Harmattan wind engulfs the West African subcontinent from the Sahara Desert into the Gulf of Guinea between the end of November and the middle of March.
