Somewhat weird, on one hand we have tons of complaint about babblespeak checklists, the loss of airmanship and too much use of automation and on the othe hand now we har requests for even more regulation, training and probably certification for the most simple type of approach to fly. Thank god i am allowed to fly any kind of approach to the minima set in my licence, it does not really matter if its a PAR, GLS or ILS. I have never received any simulator training for the GLS and yet we are certified to fly it to the usual CAT I limits with CAT III certification in process if the aircraft is equipped for it. Same for the PAR, since you do not need any equipment we are allways certified to use it if need be.
