A safety hat trick.
Good catch Thorny – a hat trick.
Catch 1 – 'strong mechanical turbulence'. When you consider that Bankstown has been operational since WW2 and the landscape has changed very little (apart from 'modernised' flood plains) you must wonder why – suddenly 'turbulence' has become so aggressive that it can kick seven bells out of a 'performance' air craft. Could the minister provide the 'vortex' and wind shear' analysis portion of the 'safety analysis for Bankstown – the one that was part of the 'master plan'? Just so can be sure all possible 'risks' to air safety from this very real and present danger was taken into account before runways were closed and large buildings close to the operational surfaces appeared and that data was properly assessed. If HP Jet traffic is being belted around what chance the mutt in the Tupperware?
Catch 2 – No doubt the crew obtained and studied the BoM forecast before departure. There may have even been a one line warning – turbulence below XXX feet – fair warning – but BoM rely heavily on 'models'. Now it takes time and data to construct a 'model' – so have the BoM been feeding the effect of additional construction data into their model as fast as they can? Have they set reference points and monitoring equipment to measure the effect of 'new' topography? I feel sure the minister has this information at his finger tips; perhaps the McDonald inquiry could ask him to provide it, fare for us all to contemplate.
Catch 3 – Alligators, wolves and crocodiles aside – I believe there exists – in law – a requirement to report such speed excursions and 'keeping the shiny side up'. Not filing a report is a double crime (IMO) : but such is the fear of CASA taking the thing to some extreme length for 'safety' reasons that both industry and BoM are deprived of valuable data which may, just in time, help avoid another 'shear' induced accident.
There are good reasons for the almost universal adoption of the 'California Code' – insurance being just one of the many. There is also some pretty solid reasoning in the ICAO 'advice' pertaining to safety zones not only on take-off and landing paths, but on the alongside a runway clearances. Our minister, his department and those responsible for 'safety' seem to have found ways around what is, essentially, common sense, to dance to a developers tune – its the same one snake charmers use by the way.
Hellish din - and, until now, I thought bagpipes were 'beyond' -
