Excluding the ditching in NYC the rate of accidents worldwide where aerial filming or photography has reduced.
I believe this was down to a combination of greater awareness of risks and the increased use of stabilised gimbals.
Greater awareness came from a concerted campaign to pilots and the film industry, primarily using forums.
In the last three years the increase use of drones for low level work has probably had an impact too. (Note that drones have injured more bystanders than crashing media helicopters)
Pprune can influence pilot behaviour. My experience is that it is easier to address risks when examining a particular task, such as filming. Statistics help prove one's point!
Documenting human performance is key.
Official accident analysis falls woefully short in gathering the wider circumstances of the crash, such as pilot pressure ect.
Without a dramatic improvement in accident reporting to inform training and awareness programme, will anything change?.
We don't even know if accident rate per miles or hours flown is increasing or decreasing.
Can aviation authorities can come to the party and introduce a requirement for a report that details the task involved for each hour flown? Anonymity or comercial in confidence regimes could be employed?
Such an annual breakdown is of commercial use to owners and charter companies.
Specifically, what task information would be useful for the industry?
