Questions on catapult officer

No I'm not confused, it seems after seeing holdback bars on the deck they leave the holdback link inside that bar so all they have to do is just slide it to fit into the nose gear. But from the pic you put up of the nose gear what does the end of the holdback link (the part that attaches to the plane) look like? To me from the pic it looks like a T that fits inside that slot on the LG, then when fired just drops down. Am I not correct?


Question where are you finding these pictures, i did a search and found nothing but that PDF file.

The holdback link itself is part of the plane, the nosegear to be more accurate. It is the little thing in the first pic that sticks out from the back of the nose gear. It kind of looks like a giant electrical plug, or clamp.

microbrewst, definitely I had no idea about this new arrangement for catapulting. No wonder I'm confused.  ::) It helps to have / use the new correct terminology as indicated. That will help searching for info on the net. Thanks for the illustrations - they really help get the picture.

You know from seeing this image it seems that the clamp on the back end of the gear is put inside the holdback link and then when fired the link drops down and the LG is released from the plane.

And why do they need to have the ability to slide it, if they use different ones for different planes? When would a plane be at a different elevation?

Dont confuse the terminology. The holdback BAR and the holback LINK are two completely separate things. The clamp IS the holdback LINK. It is part of the nose gear and is what they connect the holdback BAR to. The holdback bar then connects to the deck and keeps the jet in place.

As for the sleeve, think about a jigsaw puzzle piece. Because of the shape, the only way to fit one piece into another piece is to lay it over top and push down on it. That is the same way the bar is connected to the link. If the sleeve couldn't retract, you couldn't put the fitting from the bar into the link. Then the sleeve goes over the connection to hold it all together.
