I managed those bars for 18 years, pain in the butt, really neat to understand the functionality of the T45 RRHB; also worked the T2's on their throw away bridles, during their final days of flight ops.
That's not a Hawk exactly but a Goshawk which is a carrier-based variant of the BAE Hawk. The older ones were partially built by British Aerospace (now BAE) in the UK but the newer ones were wholly built by Boeing in the US.
@@bigred5287 When did the newer ones enter service..? Im sure there have been no "New Builds" but older T45A's have all been upgraded to C spec...If thats what you mean, the last being delivered in 2009...
Cool video. I made and inspected several of the components that go into the hold back bars when I worked for GE Aviation. It's good to see them in action.
Waist Cats, Connie (CV-64), 84-87. Nice video ABE! Thanks for the trip down memory lane, not much changes in the Nav. We still used T-bars back then. We also CQ’d the first F/A-18’s (they had a few crashes due to main gear collapses during recovery). Loved launching the F-14A the most with its afterburner crackle. Never was a training carrier. Are you on the IKE? JFK? TRUMAN?....I can’t tell.
what material is that hold back bar made of...are there different color coded bars for different needed strengths ....what happens to the bar after the launch...are the bars reloaded and reusable ........thanks
Pilots taking too long to advance throttles when the catapult goes into to tension. I don’t think these pilots have been well versed. Once the steam catapult goes into tension and there’s a malfunction! That pilot is going flying whether he is ready or not so he might want to be throwing the coals to the fire faster than that. I was a yellow shirt in fly one on a carrier did two med cruises. It’s just a little nerve racking when a pilot who is obviously either not paying attention or is over tasks in his airplane to not go to full power on a tensioned catapult. Just saying
My understanding of the function of the launch system is that the catapults are set, per plane, to apply only the amount of force required to get that particular plane and its load out airborne along with the thrust of the plane’s engines and the holdback bars are calibrated to only release with the combined thrust of the engines and the catapult. Point being that neither the catapult or the engines alone can break the holdback bars preventing what you just described. Not disputing you, just wondering if I could get clarification. Thank you for your service.
Those are “Training Pilots”, flying “Training Jets”. That’s the reason why things aren’t happening rapidly on the Catapult. And normally, this is a good time to train newly catapult crew on basic launches.
Thanks for this video I now understand the holdback bar better (I thought previously it shot along with the shuttle and maybe off the front of the carrier lol). Cheers!
As Ima said, it holds the plane back while it is at full throttle waiting for the catapult to launch. My understanding is that it is calibrated to only “break” free if the combined force of the plane’s engines and the catapult exceed the amount of thrust required to launch that particular plane with its payload.
The shuttle (the thing in front of the plane is a open hook and so if the pilot went to full throttle the plane would simply roll forward (only the brakes holding them in place) and fall into the ocean. The holdback bar is essentially like chocks and hold the plane back into the shuttle until launch when the catapult is pulling harder than the thrust is pushing forward. And it drops at the moment of launch allowing the plane to roll. It’s simple (I mean you could have some other crazy device like a hydraulic clamp that gripped the hub of the nosewheel and released but that sounds fiddly (plus steel is strongest in tension)
Dave Yates it has an internal locking mechanism that releases when it reaches a certain load. It is specifically designed to be reusable. there are fingers attached to each jet that it hooks to.
It is the weight of the aircraft fully fueled. Pilot will give thumbs up if correct, if not he will signal higher or lower. The weight is needed so they can set the correct pressure for the catapult.
Weight board. On the reverse side is a mini grease board where you use a grease pen to mark the airplane side number and weight so when it pulls up you can match the weight of the plane then confirm with the pilot who gives an up or down to correct weight or thumbs up and in some cases a salute for confirmation. You have little hand cranks on the side to adjust the weight. There is also a light inside the weight board for night flights. The weight board operator also makes sure the Jet blast deflectors are clear so they can be elevated by the JBD operator.
That's the "hold back bar" that holds the jet back, prevents it from launching, until the catapult is at full power and the jet engines are at full power. The bar is calibrated to let the jet go at the specific tension, so the cat has enough power to shoot the plane at adequate speed.
They inspect the bar after every launch to ensure it's safe. Jet planes don't have enough power to get airborne by themselves on such a short runway, so they need the catapult's pulling power to get up.
If not used the plane would solely be staying there by its brakes and with the turbines at full afterburner that’s asking a lot for brakes (oh and the deck coating to hold it in place ) and if the jet were to roll on its own even at afterburner they’re going to fall into the sea off the bow (which is a lot of paperwork for someone!) so the bar holds them into the catapult until it breaks open at a given load as the catapult throws it to flying speed. As an analogy it’s kind of like watching top-fuel dragsters at the start, the brakes can sort of hold it back (and when the go full power the rear wheels spin while the front brakes try to keep the car from flying down the track as the warm the tires) except with a jet the wheels aren’t driven so no wheel spin, and those turbines could like drag the jet with the brakes locked slowly down the deck, way below stall speed, and into the sea it would go, so a mechanical parking brake is what the bar acts like that auto releases.
also i cant get an answer. the jets taxi to cat exactly straight. are they that good. what if its crooked. you cant back up ? i taxi a cessna 152 almost straight.
When the guy touched his nose is to have it fix the crooked as you say no they'd have to go back around no reverse they do push back it takes people but it's being directed straight on so it catches not just for fun
@@christianrosa1120 We managed to make an A-3 back up. Stand on the left brake and run full up on the left engine; this causes the right wheel to roll backward. Then you stand on the right brake and push the right engine up, and the left wheel will roll backward.
@@WootTootZoot that’s the answer to “MAY I land a helicopter on the carrier?” and anyone who is asking that question, the answer is “no, no you may not!”
The kind of Tech that keeps working in the hardest conditions and can be fixed in "no time" if broken. Imagine an automated (robotic) computer launchsystem that breakes down during war. They have to call company maintenance, fly them in, do some diagnostics to figure out whats the problem. Order parts, fly them in and install them... the cat would be out for weeks, by then the war is over.
Scott Baines -not certain since I can’t see the Island or bow number. Also the USMC training squadron doing basic CQ here of course are not part of this Carriers airwing so no tail designator. Depending on the year this footage was filmed it could be the JFK, IKE or Truman but actually it also could be any available carrier at the time. The Navy has not had dedicated training carriers since Antietam and Lexington (retired in 1991). These grand old battlewagons did not have Catapults powerful enough to launch heavy jets like Tomcats and Whales. Their decks were wooden and metal combos that were too fragile for those aircraft. The JFK picked up most of this duty with others filling in. Money is the reason why USN/USMC has no dedicated training Carrier.- Waist Cats, USS Constellation (CV-64), 84-87.
Still don't understand what the holdback bar does? Does it hold the plane until the cats let loose? Jesus, I'd get lost in the hallway "maze" below decks!
Wayne Grant I looked up Area 51 Nevada or Groome Lake Nevada and saw Area 51 on my phone. I zoomed in and saw 2 runways and 2 white planes which may be Janet Airlines. On Google look up Janet Airlines. At the end of the runway there's a slice of bread thing which isn't a physical structure. I think it's to tell the pilots where to land and take off.
Jesus…and everybody wants to know why Foreign countries know exactly everything about US Carriers methods and procedures. Why is it that nothing is secret anymore? Damn, with all of the questions circulating about how US Aircraft operations are conducted, you might as well throw out the whole NAVAIR Manuel. Some things shouldn’t be spoken to those that didn’t go through what you did.
Dude this is hardly some secret thing. First off those are training aircraft so nothing secret there, and a holdback bar is like 1950’s tech (it’s a steel bar with a hole in it that literally holds the plane back).

how do they not go deaf standing behind that jet?
Thanks for this video I now understand the holdback bar better (I thought previously it shot along with the shuttle and maybe off the front of the carrier lol). Cheers!
What is the reason for the holdback bar?👍👍🇺🇸🇺🇸
it holds the jet from overrunning the cat shuttle when it goes to full power before its launched.
As Ima said, it holds the plane back while it is at full throttle waiting for the catapult to launch. My understanding is that it is calibrated to only “break” free if the combined force of the plane’s engines and the catapult exceed the amount of thrust required to launch that particular plane with its payload.
Are these jets like a Playskool version that boot 2nd Lts learn on? LoL..
Very good video not music
1:52 He is so cute!! 😄😄
Nice video of cat ops.
What, specifically, is the function of the holdback bar?
I think so this easy jobs
It keeps the aircraft from taking off while the engines are running and the plain is locked into the shuttle.

Dave Yates it has an internal locking mechanism that releases when it reaches a certain load. It is specifically designed to be reusable. there are fingers attached to each jet that it hooks to.
Dave Yates Bridal launches went away with the final launch of The T2 And the A4. All launches use the RRHB ON THE current inventory of Naval Aircraft
They'll need maintenance upkeep and then replacement they get super heavy after some hours
I was wondering the same thing- looks like a torque bar in reverse, smart engineering.

What are they doing at 4:12 ?
How does the holdback bar work?
How does it release from the jet?
What’s with the fisheye lens? Very distracting, could only watch about a minute and half.
I think its a wide-angle lens as opposed to a fish-eye lens. They don't choose it, the Navy does, they all take turns wearing that camera.
whats the black box camera looking thing the guy is holding up in his arms at the pilot ?

All carriers can do training operations, the jets are trainers, at some point you gotta actually operate off the real thing!
