This is something that has been happening with their products for a loooong, long time. They never seem to have addressed it after all these years. Been flying their products since FS9, and neither of their products were ever able to follow glide slope precisely down to minimums, let alone autoland. I was hopeful that it will be fixed with Embraers E-Jets V3, but here we are, same old problem still exists. Even after two service packs. It kinda starts alright after capture, but soon it starts to struggle to stay both on commanded speed(speed is never on point, it goes +/- 5kt the whole time) and glide slope, it gets to the point where somewhere down the path it completely loses it. A/T being as it is in current state doesn't help either, so by the time you're at or around your minimums, you often have one, or sometimes TWO dot deviation on the glide slope. Few days ago I got SINK RATE warning at around 500' AGL while the autopilot is in autoland1 mode, because the glide slope deviated two dot under, and the aircraft chased it nose down into the runway. By the time it started to flare, it was already too late. Landed nose gear first, I believe my VA acars showed around -900 feet/min with an excess of 3+ G of force. That's not an autoland, that's a crash.
And before you ask, I have tried flying it with my joystick unplugged, took off with mouse and went on automation right away, just to rule out hardware issues. Weather was also not a factor that time, because I didn't start Active Sky, again, to rule out that factor as well because I know that aircraft from some other vendors have problems with how wildly Active Sky simulates weather conditions. And lastly, used a default airport for the test. Landing configuration doesn't matter either, happens with both flap 5 and flap full landings.
Don't get me wrong, I still fly your products and enjoy them very much, E-jets V3 flies really, really nice while hand flying, but they are not capable of autolanding which is not a problem when visibility is ok, but winter is coming, and with it, LVPs across the whole Europe. Can't land manually when there's 0 visibility.
I hope this finally gets looked into for the next service pack, if further development is even planned.
