Last non-GPS aircraft I flew was on June 24, 2023 on a B757. Yes, a B757 with no Global Navigation Satellite System, using the 3 IRUs and DME/DME updating enroute. Can't remember the last real-world NDB approach, but I still use the RMI in the same way as an ADF to ensure my raw-data VOR radial doesn't show any shift with the LNAV path depicted on the Navigation Display as the B757 does not have a VOR track capture mode on the AFDS. Back on the B727 (steam gauges) used the RMI much more frequently to track a VOR leg outbound before a teardrop turn onto final, that way I could have the inbound radial preselected on the HSI and didn't need to twist the CDI course selector mid-turn. The RMI with VOR works much the same way as an ADF (but is much more stable). Thanks for the trip down memory lane!
I like this kind of 'gentle slap in the face' video. It's good to remind aspiring pilots that real life isn't full of apps which will do all the hard work for you. If ya wanna be like Joe and fly REAL Boeing 747s for a living, you either get your brain in gear pronto, Tonto, or you stick to downloading endless upgrades and bug-fixes for your bedroom flight-sim.
As luck would have it, I am training for my class 4 flight instructor license and am currently looking to create a PGI for exactly this subject, so this video came at exactly the right time for me. I've never actually used the ADF to navigate in my little c172 since GPS is nearly foolproof, but from my studies I can say with complete certainty that the two aerials in question are the loop and sense antenna.
NDB will be a memory like AN ranges of the past. At my airline we had NDB approaches in the FMC but we flew them with the FMC and the ADF was only used to show raw data, the only time I ever flew them was in the sim. Last time I flew an NDB approach in an airplane was in the 70's in GA airplanes during IFR training.
Back in the day (at least through the 1970's) AM broadcast stations were shown on VFR sectional charts along with their frequencies and call signs. Eventually, the FAA stopped charting them. I suspect a lot of pilots were using them for navigation or, even worse, creating do-it-yourself instrument approaches.
Come up with a video to do with fronts and the weather related with them i.e..when approaching...upon arrival....and after they have passed.... detailed one....
Dear Capt Joe, The first shown picture describing QDM and QDR both planes are headed toward the NDB which needs to be graphically corrected. Thank you I always enjoy your instructing videos
Y fly conventional SIDs and IACs every day (VOR-ILS-DME), even NDB approaches. Old gauges is all I have in the old BE20. When I flew the metroliner, NDB approaches was a daily thing! ❤️
Sense antenna is for resolving ambiguity...i.e....loop aerial doesn't know where the NDB signals are coming from...they can be coming from the front, sides or back....sense aerial resolves the ambiguity and as a result the ADF pointer can now point at the NDB.
Long to medium wavelength signals mainly propagate as a surface wave and electric conductivity plays a huge role in it. Seawater is an excellent conductor, rock and soil are not.
Happy day was taking my plane in to get rid of the ADF and pounds of wiring. They served their purpose way back when. It’s hard to find a VOR anymore, the NDB’s are gone. And with Sirius XM in the plane, I can get get ballgames without an ADF!!
NDB are still found in very remote areas where VOR beacons never replaced them due to the expense to install and difficultly to maintain. Alaska still has quite a few NDB, and I'd wager some less developed international locations still find NDB more desirable in light of unreliable technician quality.
Without reading the comments which are bound to be full of correct answers, the best I can come up with are gyros and magnetos (you can tell I’m not a pilot). I did watch an Amelia Earhart video which talked about a loop aerial she was using to try and locate the small island she never reached - could that be part of the answer? Incidentally you speak excellent English, but “bearing” is not pronounced “beering” but “bare-ing” as in teddy bear.
I learned flying with NDB and ADF back in the 80s when getting my IFR rating. First we'd fly to and from stations at predefined bearings, then practice changing bearings to/from the station (QDM/QDR change), then holding patterns with NDB and finally doing NDB departures and approaches. Fun stuff. The answer to the test is given at 05:43, "loop & sense" aerials. The latter solving the ambiguity of the loop antenna's front/back sensitivity pattern.
Finally a proper Captain Joe Video. This is what most of the people here want. Just pure aviation knowledge

The two aerials (or antennas) are called the loop and sense aerials. I learned first from Veritasium's video on Amelia Earhart.
Same here, awesome video

In the Netherlands all NDB beacons have been phased out (except on the North Sea for offshore platforms), it's all VORs or GPS now.
2 weeks ago i used RTT NDB, for my revalidation, only for simulated IFR approach, but it brought me save to 'ADWIG', and thereafter to LOWI.

Awesome video. Thanks captain.
You just missed the fixed and variable card on the instrument and how to adjust them.
That iis the loop antenna and the sense antenna. We ham operators use similar antennas on or fox hunt receivers. On other ham frequencies of course.

and to listen to some music enroute.

Dear Capt Joe,
The first shown picture describing QDM and QDR both planes are headed toward the NDB which needs to be graphically corrected.
Thank you
I always enjoy your instructing videos
Back in 2019 when i did my CPL IR, our Cessna got caught in the active cumulonimbus. The adf went crazy😂

My first instrument approach qualification was on the NDB. However after my training never used it, and moved on to VOR, then ILS and finally RNP.
I live tour videos captain joe! What is your favourite : boeing 777x or a350
Sense and Loop aerials
Together they solve the cardioid.
yeah that makes sense
Loop & Sense Antenna 😊🛩
sensing and loop aerials are used together
The 2 Aerials are loop and sense aerial system
Nice graphics.
Nice lamp Capt'n Joe!❤
Loop areal and sense areal to identify NDB signal.
next questions what is the range of the atc communication using the am frequency?
2 years ago I had to use 2 VOR’s to determine my position as I was practising lost procedures
Also, what does the Sense Antenna prevent? that was a common problem on ships and planes prior to its use?
Sense antenna is for resolving ambiguity...i.e....loop aerial doesn't know where the NDB signals are coming from...they can be coming from the front, sides or back....sense aerial resolves the ambiguity and as a result the ADF pointer can now point at the NDB.
Ótima noite para todos
QUE MEW LOW NIMBUS is how you say it, hope that helps you out 😁 liked and subscribed
Like your videos👍👍

MDB and ADF
sense and loop antenna
make some more interesting video mr joe likewise Mentour pilot ❤
I love to fly the DC6 in MSFS only by VOR and NDF as it was the early days. GPS is crap.
In times of GPS jamming, having a "plan B" is always a good idea...
0:24 a minute ago, my eyes...
Now do the four-course range.

Yeah, I watched Veritasium's video on Amelia Earhart. And he explained the topic pretty well.
Loop and sense aerial......sense aerial is for resolving ambiguity...
Loop aerial, sense aerial
You’ll be lucky to find an aircraft with an ADF nowadays, let alone anyone who knows how to use one.
