October 7, 20205 yr A broad question... I included ILS as it's the only one I know. Instrument Landing System. Keep the purple vertical and horizontal diamonds in the middle on final approach 🙂 But what's the rest of this? What's this for? I guess I know NDB (No directional beacon) but don't really understand that either. Is someone willing to explain it all or is there a simple Sim version?
October 7, 20205 yr You might want to get a Instrument rating 🙂 The 'rest' are basically GPS approaches that use fixes for more precise guidance. These are more prevalent today, especially for GA as they allow lower minimums to smaller airports without the infrastructure ILS systems require and need support for. SAR Pilot. Flight Sim'ing since the beginning.

October 7, 20205 yr Check out this guy's YouTube channel. He just did a whole series of all the different approach types using MSFS 2020. He sometimes runs a bit heavy on the "Dad jokes", but the info is good. Quick rundown though is LOC approach is an ILS without the glidepath info so you have to descend on your own but it lines you up still. RNAV is ILS but with GPS instead of an ILS radio. The GPS in the plane flies you down, and they tend to be a bit buggy with the glidepath info in MSFS. Sometimes it's not there, or kicks in much closer to the airport and lower down than it's supposed to. I haven't heard of an LNAV approach yet, I thought that was just a navigation type that the autopilots use for navigation in general horizontally. Maybe it's the GPS version of a LOC approach or something.  https://www.youtube.com/channel/UCGWd_NMbp7GxMg4bZO65heQ  AMD Ryzen 9950X3D | Asrock X870E Taichi | Gigabyte Gaming OC 4090 w/EK waterblock | Full Custom Loop Cooling | Corsair Dominator Titanium DDR5-6000 | Samsung & WD NVME/SSDs | Phanteks Enthoo 719 | Seasonic Vertex Gold 1200W | Keychron Q5 Max | Corsiar Scimitar Elite SE Wireless | Honeycomb Alpha and Bravo | Logitech Pro Flight Pedals | VKB Gladiator Pro NXT L&R handed | MiniCockpit MiniFCU | Alienware AW34DWF | Asus PG279Q | Win 11 Pro

October 7, 20205 yr Yes, or a 2D approach as they’re called now. As opposed to 3D which have a coded glidepath Nothing is simple anymore 787 captain.  Previously 24 years on 747-400.Technical advisor on PMDG 747 legacy versions QOTS 1 , FS9 and Aerowinx PS1.Â
