And the accident aircraft this thread is about didn't have any TCAS type devices fitted ? An accident report would be handy.
Quite correct.
Nor are they likely to have CVR or FDR. Which will make the accident that took 4 precious lives far more difficult to investigate than it needs to be. We may never find complete answers?
Bear in mind also that even a microlight has the capacity to bring down an aircraft carrying a number of people. So where do we stop with the march of 'technology'? Should all a/c be required to carry strobes, transponders, tcas, cvr, fdr? Where do we draw the line? How much kit can these little aircraft realistically carry? What are the electrical requirements? How often should this equipment be tested? Precisely when should a 'simple' (to operate) type become a type that requires all of this equipment?
Will we end light aircraft flying for the masses. (Who for a century have flown perfectly safely, year in and year out!)
