I'd like to see procedures for loading GPS encryption, COMSEC, MIDS and IFF keys as well as frequency hopping stuff (synchronizing TOD without use of GPS TOD, loading WOD etc.).
Thanks for the info. I worked on the flight deck during Vietnam when they were using the dog bones. They were color coded for the different aircraft. I have been watching U-tube videos on modern carrier activities & wondered how the new hold back devices worked. You might cover the nose tow system vs the old bridle system. Nose tow was a big advancement.
ABOUT TIME, SERIOUSLY. I was USN on CV64 Constellation and would always try and explain how the holdback bar worked. This video was more then descriptive and clear. EXCELLENT PRESENTATION, MOST EXCELLENT. Everything described was 100% accurate, including the colors of the holdbacks. Thank you so much. Bobby (cv64 AIMD 77-81)
Hey, I was on CV64 for a few months too, on a WESTPAC in 94-95. I have here on my desk right now a purple dog bone, fully intact, that I found on a FOD walkdown. Since they did not know where it came from they told me to keep it as a souvenir. Great times back then.
@@privatepilot4064 I was on the following cruise (78/79) and 1980. I went back to Jet Shop around 1980. The IM-2 Division Chief was Senior Chief Spitler, LOL. I worked for him directly. I was the AZ and eventually did the wrench turning. The ADs called me ADZ Estey. I did some of the Gas Turbine Trimming on the Test Cell, sometimes ran operations in the Test Cell. Look at the 1978-79 and 1980 cruisebooks at the Jet Shop and you might know others who I knew. Especially look at the 1980 Jet Shop picture. SO HILARILOUS, everyone else is just standing, that was picture 1 of 3. They could not print 2 or 3, we were a crazy. Bobby Estey - I have stories and one with Spitler, was so funny.
YEARS. I have been interested in naval aviation since early childhood, And I currently play DCS world with the fa-18c hornet. FOR YEARS I have wondered how the hell that holdback bar works. Because everywhere you can search how the cat works. But I could never figure out how the bar lets go without an electrical signal. Dude. You just completed a childhood wonder of mine. THANK YOU!
Great video. E2 and EA6B were still using dog bones at least through the end of the Prowler service life. I can't speak to the new Hawkeye variants as I retired in 2012.
I thought the holdback bar was a simple mechanism, but after watching this video I realized that there is actually a complex mechanism built into its head. Thank you very much!
This is a great video. Never really knew how these simple pieces of tech actually worked and it's quite amazing to see how the engineering behind it goes together. Didn't even know the bars were color-coded according to the aircraft being catapulted off the deck. Thank you for the excellent video.
Awesome explanation of hold back bar, I was CAT ONE petty officer on USS KITTY HAWK in Vietnam, 71-72. Had bridle and nose tow system back then. Much more physical work than this system,I had 4 crew under planes for bridle launch. Big improvement from 50yrs ago. We were launching. About 240 birds a day during flight ops. Balls to the wall
Would you believe I have almost 500 traps and 2000 hours in Rhinos and 2000 hours in T-45s and I actually didn’t know exactly how the holdback worked? That was super cool!
This is the best description I've run into, even better than the training videos we had at that time. We used dog bones on the A-6E Intruder back in the late '80's early 90's and I can't tell you how many of them I threw over the side. I regret that, I wish I would have kept one.
Did my service years in a West Coast E-2 squadron based back then in San Diego. When on cruise, the squadron would recognize their sailor of the month, quarter, or year with a mission flight in the squadron's E-2. The CO also allowed airborne re-enlistments during a mission flight, if requested by the sailor, and on rare occasions a non-aircrew Navy "guest", e.g., an air wing flight surgeon, could be allowed to go on a flight. Whatever the reason, the squadron line crew made it a point to keep both ends of the hold back for the skipper to present to the individual on his return along with a certificate documenting the flight and subsequent trap back aboard the carrier.
Excellent. I’ve been trying to find out exactly how these work but only came across engineering drawings or vague descriptions, which weren’t useful. This was precisely explained. Thank you.
Great video I am now teaching class to E4 for catapult test since iam now a retired 04 in Japan on the uss Ronald Regan making sure these kids pass there ABE test
Thank you. I have been super interested for many years how the holdback bar functions. Your excellent video is the first actual and complete explanation of the device that I have seen. Good job; very nice presentation.
Wow, it's pretty cool to see this after so many years! I was catapult 2 crew on the E in the mid 70's. Did weightboard, bow safety, water brakes, end speed and this holdback bar hook-up job. Back then we also still had some bridle planes which the hook-up person would also handle. Interesting times!
Nice, detailed facts of the "Holdback" one of my JOBS during my last few months in NAVY was to TEST check the Holod back in the HYD shop, one of the few things I got to do that was a learn as you go skill,
@x-planed . Thanks for the video and accuracy as confirmed by others in the comments. I've always understood the principle but have never seen such a clear and comprehensive presentation. I hope your subscriber base continues to grow.
I have watched hundreds of videos and ask everyone if anyone knows how the hold back works, No one could explain it. I want to thank you very much on your video and explanation of it. It has been bothering me for years how it worked.
Excellent explanation, I've been looking for the dog bone but none to be found until now. I still have a dog bone for an A-7 since 1973. Never knew how the re-usable hold back worked until now. Thank you.
That was a fantastic explanation of this. I wondered how the aircraft was held from moving forward once it throttled up. Saw the holdback bar, but didn't quite know how it worked. Great graphics.
Great video, thank you. Would love to try and 3D print a working holdback. Not sure what materials could be used for the strain bar though. Might have to make it in two parts connected by a tension spring instead.
I've always wondered what that thing was for and did ? great and thorough explanation ! 👍👍👍😸😺 ( I'll bet your video becomes the - go-to video to learn about it )
That's interesting. I had only seen the break design. It's fun to see the videos from the 60's and 70's where the crew lie on the deck as the plane moves into position above them to lock in the rear hold back.
I never really thought about the holdback until now - I just assumed they were standing on the brakes (which is pretty silly in retrospect!). I would also be interested in how the fitting that pulls the aircraft along the catapult disengages. Thanks! You have another subscriber.
You mean the shuttle that the launch bar locks into? It's open in the front, so there's nothing to "disengage" from really, once the catapult/shuttle stops, the aircraft is "free" (to either fly or crash into the ocean in the case of a "cold" cat shot).
@@B-and-O-Operator-Fairmont and have to add, that the launch bar position knob in the cockpit is set to "up" before the launch so it retracts automatically just after it's free of the shuttle
Very interesting. I was ship's company as a radar ET aboard the USS Forrestal in 82. I can recall being told that basically a metal link broke to release a launch on the catapult, but never really had a picture of how that worked. Only time I was ever out on the flight deck was when the airwing wasn't aboard, so never got a look any closer than vulture's row (a catwalk on the outside of the island). Even more interesting to see that mechanism has been replaced.
MOST SUPERIOR!!!! I have been in the USN for 20+ years, not on A/C carriers, but on escort ships..... BUT, now retired, and building models, I ALWAYS Wondered .... literally for Many years, what that "rod" ( I called it ) was on the back of the nose gear? I understood the concept of the shuttle launching the A/C and the "green shirts" job, but Never knew what that "rod" was for........... UNTIL NOW!!! Thanks for the Superior explanation, and Now that I know that there are different colors of those "holdbacks" and how they actually work, it brings a small but Vital part of my model building!!! MayBe....I'll show that in my upcoming build and post that Here!!!
Aircraft Catapult launches from topside is simple to explain. It’s the below decks movement that needs to be learned on how it all ties in to make launching happen.
If you would like to learn the principle of operation of another device or procedure related to aviation - let me know in the comment
I'd like to see procedures for loading GPS encryption, COMSEC, MIDS and IFF keys as well as frequency hopping stuff (synchronizing TOD without use of GPS TOD, loading WOD etc.).
Could you do a throwback to the entirety of the “meatball” or fresnel lens system?

This is a great explanation of a part no one would give more than a passing glance to. Thanks!
Pretty incredible that a “simple” piece of equipment can hold back that much thrust and steam pressure. Engineering at its finest
Steam pressure doesn’t hold the aircraft back. Different aircraft require different holdbacks. Steam pressure is what launches that aircraft.
Great video. E2 and EA6B were still using dog bones at least through the end of the Prowler service life. I can't speak to the new Hawkeye variants as I retired in 2012.
You bet. And they’re still using holdbacks other than F-18 but I couldn’t find anything about them
Absolutely right. E-2s and C-2s are still using "dog bone" holdback fittings to this day.

This is the best explaination of the holdbackbar I found on YT! Very detailed! Thank you very much!
