A few questions for pilots who fly RPT in and out of non-towered aerodromes in Australia:
1. What is your assessment of the extent of your collision risk with other aircraft in the vicinity of non-towered aerodromes, caused by the pilots of other aircraft being on the wrong frequency, not selecting the correct radio to monitor or having its volume turned down, or mis-identifying or mis-reporting their location and ETA?
2. What is your assessment of the extent of your collision risk in Class E airspace, caused by the pilots of other aircraft not having a serviceable, operating transponder and not monitoring the frequency for the airspace and not self-announcing, or giving incorrect information when self-announcing?
3. If your assessment of the collision risk in 2 is higher than in 1, what assumptions are you making about the density of traffic in each scenario and what assumptions are you making about the competence of the other pilots in each scenario?
4. If your view is that the collision risk in 1 is higher than in 2, why are you prepared to risk yourself and your passengers in 1 but not 2?
