Ditto for me. The PVC chock works great for me. I also have tie down ropes and anchors that I carry, especially for fly-ins.
Years ago in my corporate days, we did a trip to Dillingham Alaska. We were truly unprepared, and the FBO was, well, basically non existent. They had no chocks. (Nobody even parked us). We were overnight and had to go to the woods to get logs to chock the jet the best we could. Low oil light the next day. Thank god for Alaska airlines rampies giving us oil. Had to improvise for ladder and funnel. Not fun. So happy to be with airlines now.
I carry a Tupperware box with enough oil for an oil change, 2 sets of chocks, “The Claw”, a few spare plugs, GATS jar, fuel dipstick, paper towels, handheld battery powered compressor, window cleaner, and microfiber towels.
I'm sure there was one somewhere along the line, but I do not remember any of the rentals I've flown ever having any. Some of the schools I've rented from chocked the planes but most just tie downs worked. If I owned a plane, I'm pretty sure that true to my form as a "boy scout", I would almost certainly have one pair of something light weight, along with ropes and a set of those claw things. I've seen those cables lots of times over the years. Almost always they look extremely sketchy. I'm not a fan.
I carry 2 sets of low profile aluminum ones. I have a castering nose wheel so prefer to chock the mains and most FBO chocks are too large to fit under my wheel pants. I also carry a set of tie-downs and my cover.
I made a set from some aluminum SQ tubing. Cut to angle iron with plasma cutter. Daughter cut the numbers on her ? Machine.
One wheel chock for my Arrow plus the "Claw" and ratchet straps for tie-down. 3 -10 inch by 14 inch by 1/2 inch thick aluminum plates for soft ground. Also a full cabin cover and cowl plugs, oil cooler inlet plug, pitot cover. Controls are locked by a strap between them and snapped onto a bracket screwed to the center console. I am a "belt and suspenders" guy.
I got a set of the "claws" but I don't carry them everyday because they are too heavy, IMO. I use them a couple times a year when we camp at a turf airport. Rest of the time they spend time in the hangar.
I also carry ratchet tie downs, but they are heavy. I have ropes also which don't weigh anything. Sometimes I leave the ratchet straps behind if I have a lot of cargo. The ropes work just fine if the FBO does not have them.
One. Been plenty of places that didn't have chocks readily available. Instead of dicking around for 20 min trying to find a set, its easy to just throw a pair on the nose wheel and be on my way.
