Invalid airport runway instruments meant to assist with ground-based landing during poor visibility, have affected Airlink operations to Polokwane.
The airline issued a statement saying its scheduled services to Polokwane are being "disrupted from time to time specifically when there is low cloud in the vicinity of the airport due to the unavailability of the airport’s instrument landing system (ILS)".
They were advised of the issue on Monday May 13, after it affected the morning flight. The flight was first delayed by one hour and then cancelled all together, before being combined with its next flight, says Airlink.
The statement explains that "ILS is an essential ground-based landing aid used by pilots to accurately and safely guide aircraft to the runway during inclement weather and poor visibility. ILS’ require regular calibration to validate their accuracy. This task is performed by the South African Civil Aviation Authority (SACAA) using a specially-equipped calibration aircraft".
However, the SACAA’s calibration aircraft is "currently unservicable and the certification of the Polokwane ILS has now lapsed, flights may only land and take off from Polokwane airport when visibility on the ground is good" says Airlink.
Airlink says it is working closely with the SACAA and Polokwane Airport management to mitigate the impact of any disruption and to expedite the calibration of the ILS.
Traveller24 has contacted the SACAA to confirm when it would be able to perform the crucial task and is awaiting a response.
