CAOSCvmeans Congested Areas Operations Safety Case. Its an assessment that considers all elements of the comapanies drone operations in congested areas (including airworthiness).
All CAOSC assessments will be conducted by the CAA.
The CAA make it clear that the CAOSC does not replace the requirement to hold an Operations Manual and any significant changes to the Company’s CAOSC will require further assessment.
Also, operators should ensure that any changes to their Operations Manual do not significantly affect the CAOSC.
Where changes to equipment, company policy or operating environment (within the period of a current permission) significantly affect the CAOSC, a new application for reassessment must be made.
