My understanding is the 150nm calls are being made under agreement between Qantas and the CA/GRS Units in order to improve the CA/GROs situational awareness as discussed under point 1.
And that is part of the problem. Sweetheart deals/arrangements, excluding everybody else, where easily convinced pilots think "oh yea, that sounds like a good idea, I might do it as well", leads to undisciplined rabble on the RT, clogging up the airwaves, as is occurring now. The verbal diarrhoea on CTAFs at times is disgraceful.
If it's perceived by the Skygods
and the CAGROs (and CASA?) to be necessary, why aren't the rest of the High Cap community doing it as well? Are their pax less important?
