Continuation of Risk Assessment and Management
RPA DETECTION OF HAZARDSRPA may detect hazards, including conflicting traffic, using optical and non-optical technologies. Detection may be supported by the use of a database (e.g. terrain and obstacles). Optical techniques: Optical techniques are based on visible and near-visible (ultraviolet and infrared) EM radiation. Examples include video, light detection and ranging (LIDAR) and thermal imaging. Non-optical techniques: Non-optical techniques are based mainly on radio-frequency electro-magnetic (including microwave) radiation. Examples include primary radar, SSR, ADS-B and multi-lateration. Non-optical techniques are generally not dependent on meteorological conditions.
Hazardous meteorological conditionsUAV operations should not commence or be aborted if :
- high wind or wind gusts in excess of UAV manufacturers recommendations
- fog and smoke
- other airborne hazards, including wake turbulence, wind shear, birds or volcanic ash.

Ground impact risk analysisThis analysis is focused on estimating the risk level of RPAS operations related to loss or crash of the RPA. It is not focused on the technical causes of the incidents. Essential input is
- The expected consequences in terms of loss of human life or damage to property and
- The associated probabilities of such loss/crash incidents.
Risk mitigation measures
Elements of a job safety assessment (JSA) for the operation of an RPA;Risk assessment is an essential part of the risk management strategy and is used to determine what risks will be tolerated, mitigated (controlled), or in some cases, avoided. What follows in this section, as well as in Risk Assessment – Risk Analysis, Risk Assessment – Risk Evaluation, Risk Treatment, Monitor and Review represents elements of a potential risk management process that you may wish to implement in your operations. No warranty is given that this will be absolutely suitable for your organisations, and you would need to amend this according to the environment in which your organisation operates. The process is initiated when:
- an assumption made about risk in the Job Safety Assessment (JSA) is no longer valid,
- the JSA identifies a new risk, or;
- a new operation is undertaken which requires a permission, approval or exemption from CASA or other State or Federal authorities.
- communication and consultation
- establishing the context
- risk assessment
- risk treatment
- monitoring and review.
Communication and Consultation:Where possible, any person affected by a risk should be identified and consulted with at each stage of the risk management process. The consultation process requires the sharing of information and should provide the genuine opportunity for all people affected by the risk to be part of the decision -making process. Clear, open and transparent consultation is a key element in successful risk management practices.
Establishing the context:In addition to communication and consultation, the context of a risk should be established in terms of its compliance with legislative standards and operational/organisational environment. The following steps should be undertaken to establish the context:
- Topic Objectives – Clearly articulate the specific objectives of the RPAS activity that will be undertaken, including locations, proposed time of operations, etc.
- External Environment – identify and consider what additional matters may need to be considered. This may include the identity of key stakeholders, legal/regulatory requirements from other State or Federal authorities, technical matters relevant to the risk, other activities or sensitivities that may impact on the risk, etc.
- Internal Environment – identify and consider if there are any special internal requirements that need to be considered, including staff training, human factors, reliability and suitability of equipment etc.
- Stakeholders – all stakeholders that may be impacted on the risk need to be identified. This may include the client, other airspace users, members of the public, public interest groups, owners and occupiers of buildings, and Local, State or Federal authorities etc.
