Flight Calibration Services back
The Flight Calibration Services staff are back on St Helena with the South African chartered turboprop aircraft performing further calibration checks of the airport's navaids.
Today it looks as if they have been doing at least 3 orbits some 20 nautical miles out, which suggests to me they are checking out the VOR performance which was previously compromised by the position of the metal security fencing.
Maybe, if they find the performance acceptable, the blank VOR/DME approach will be authorised.
Not that that will help with turbulence and windshear problems, of course.
