Genghis,
You quote UK CAA safety data that quantify fatalities as a function of flight hours...
Airlines - tiny numbers
Certified GA FW, large helicopters: approx 1 fatality per 80,000hrs
Smaller RW, microlights, gliders: 1 fatality per 40-50,000hrs
Homebuilts: 1 per 25,000hrs
Gyroplanes: 1 per 6,000hrs
Please define "tiny numbers". For example, if the fatality rate for large helicopters is 1 per 80,000 hours, is the airline fatality rate per 80,000 hours .1, .01, .001, .0001?
