Genghis - the whole thrust of this argument is that those with JAR 66 Cat A have had to go through the hassle of obtaining a licence to hold the same privileges as the pilot having no engineering licence whatsoever. Makes the stipulations of the above referenced JAR a bit of a farce. Do I think pilots should hold CRS certification (assuming they do not hold JAR 66 A, B1 & B2)? No, I do not, for the reasons stated by other LAES (two of whom I have known for years) on this topic.
