Just a point of interest more than anything else…….in the Southern Hemisphere SBAS does not yet exist. Something Northerners seldom know as they have been so lucky to have SBAS for many years now allowing LPV and L/VNAV approaches, mostly the former. Australia and NZ will be first to get SBAS (called SouthPan) in about 3 years from now. So LNAV + V and L/VNAV using Baro VNAV are the only RNP based approaches available, hence pilots here are quite used to them. Some of the smaller GA aircraft don’t have Baro aiding and air data computers on board so LNAV+V is it…..the best we can achieve for many GA aircraft here. Oh, here we are only allowed 1/2 scale deviation on CDI as a pilot tolerance……. BTW your IFR knowledge is excellent……what’s your flying background? Cheers
@miket3445 - thanks for the info on your area of the world. It sound like SBAS is coming to most of the world eventually, but it will take some time. Even in SBAS covered areas there are still a fair amount of LP & LNAV approaches - so if someone wants to be a well rounded instrument pilot, it is wise to learn the procedures for flying +V type approaches - even if you are operating in in these SBAS areas with an SBAS capable receiver. (Side note: I don't think MSFS emulates Baro aided/compensated ADCs or receivers. Let me know if I am wrong on that.) You can also turn off the SBAS function on the GNS 530/430, if you want to go really "old school GPS approach" without even advisory vertical guidance. (And I just happen to have a video on that topic here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eC52hp2BWaI.htmlsi=eMIYAku8zqWAQ64M) As far as background, I was a part 91/141 CFII/MEI for many years before moving on to 135 and then 121 operations in the US. Thanks for watching, and for your input - and for the kind words!
