Something doesn't jell...
The Argus Consulting Group study for Launceston Aerodrome, December 2009 doesn't agree with any of the NPRM as per the proposed changes to FAA class D
In addition to the modelling discussed above a comprehensive a qualitative airspace risk assessment was undertaken including AS/NZS 4360:2004 assessment with comparative risk ratings applied.
In consideration of the input from all stakeholders and their respective replies to structured and unstructured questions on specific areas of potential risk, it is arguable that the airspace contained with 35 nm of Launceston is acceptable from both an operational (efficiency) and a risk perspective. This would appear consistent with the application of a limited quantitative assessment as set out at Section 3.2 and indeed supported by the
absence of any discernable pattern of incidents or accidents. Again, this is not inconsistent with previous findings and reports.
An argument could be made that, in an attempt to overcome inefficiencies, safety can be compromised inadvertently. Consequently this review raises a number of issues that either directly impact upon the safety of operations, or indirectly have the potential to impact on the safety of operations within the airspace.
