Before a job can be carried out a Feasibility Assessment must be performed to ensure all risks are quantified and considered. The Feasibility Assessment process may need to be re-visited a number of times before the job can be initiated. The Feasibility Assessment includes the following questions:
Does the proposed job meet the legal provisions of 3.1.4 Normal Procedures?
- All up weight of the aircraft does not exceed 55lbs (25kg)
- Below 400 feet AGL altitude / Within 400 feet of structure
- Outside Controlled or Restricted airspace
- Greater than 3 nautical miles from a registered aerodrome / ATC permission
- Outside populous area
- Able to maintain more than 30 metres from persons not involved
- Within Visual Line Of Sight (VLOS)
- Day Visual Meteorological Conditions (VMC)
- The operator is licenced, current and well rested
- Within the privileges provided by the regulator
Manage your Risk:
What hazards specific to the job will arise? These need to be identified, the risk analysed for probability and potential severity, and then mitigated so that the hazard is controlled. We can identify the hazards by researching the following issues:
- Location of nearby aerodromes/restricted aerospace
- Suitability of forecasted weather
- Review of related NOTAMs
- Possibility of people moving into the area of operation
- Ability to maintain 30m separation from the public
- Suitability of possible take-off and landing areas
- Obstructions (buildings, trees, wires etc.)
- Sources of radio interference (power lines, train/tram overhead wires, antennas etc.)
- Ability to maintain Visual Line Of Sight
- Controllers ability matches task
- Permission from land owner
- Local restrictions & by laws
- Need for signage
Risk is the effect of uncertainty on objectives. Risks can be characterised for priority and treatment by completing a Risk Assessment Matrix. What is the nature, seriousness and likelihood of the harm that could be caused? Analyse and evaluate the risk.
Control and Mitigate Risks
Could the hazard be eliminated altogether or perhaps controled so that harm is unlikely? Is there a less risky option? Find a defence. Note your findings and carry them out.
Review any findings regularly and update this manual to ensure they are working as planned.
