Thank you so much for this video! I've watched many, many videos learning ADF/NDB navigation and while there is great content, your video is the first to actually explain where to find an NDB's frequency. Great instruction!
All Offshore rigs (in the whole wide world) such as Drilling rigs, Oil/Gas Fixed Platforms, FPSO vessels, Exploration Vessels etc are still equipped with NDB's and ADF's are still used by helicopters serving these rigs.
When I first learnt to fly GPS wasn't really a thing, so I flew round the UK using VOR and NDB beacons, found Humberside Airport by homing into it's NDB, I think they're great, shame they're a dying thing...
That's correct: the accuracy of NDBs is relatively poor even under ideal conditions, and non-ideal conditions are make results much worse. VOR has been the main en route navigation aid for many decades, but in the United States the FAA is phasing out some VORs as part of their NextGen initiative (where GPS plays the key role). DME (distance measuring equipment) is also used widely for en route navigation and I believe the FAA is planning to actually expand DME coverage as it reduces VOR coverage, partly as a backup in the event of a GPS outage. Note that this applies to the United States, and the situation may be different in different parts of the world.
Still has it's uses. Like you could have it point towards your final destination if avaliable as an additional aid if for some reason you get lost. Obviously you should check every so often to ensure you're still picking up the correct signal but for the most part it can give you a picture of where you are heading should your primary navigation source fail. It's not ideal but certinly an easy way to figure out relative position on a paper map if forelflight crokes on your iPad mid flight. (Don't take this as professional advice, I'm not a pilot, just a simmer).
The voiceover says "quite a few NDBs in the United States are unmodulated" while narrating a slide that says "unmodulated NDBs are very uncommon" in the US. Which is correct?
Twelve thousands views and you're the first one to catch that :) Yep, absolutely correct - thanks! Incidentally, I both write and "narrate" my presentations, so the fault is doubly my own :)

Glad it was helpful
Thank you so much for the time and effort you put in this video. VERY helpful!
lovely, thanks! definitely sticking around for more of this stuff
Very informative video and well explained

Agreed - sad to see them go.
Genius 💯💯
So due to the inaccuracy of NDB's they are no longer used regularly and now VOR and GPS are commonly used?

If you look at a recent sectional chart, most of the NDBs in the United States (nominally) have a Morse ID, so the slide is correct.
Slide 12 shows accuracy using percent symbol, should be degrees per narrator.
