You will still have your clip when I can find a supplier of them.
There were suggestions that to stop students charts disappearing down under the rudders or what ever they have on helicopters when the student has it on thier knee. A slide grip might help.
Must admit personally made them put it away so they couldn't feature crawl. Some sort of removable clip (instructors won't be wanting it) which could trap the chart but not be a fiddle to release it. The bull dog clips are used by people who don't know how to fold a chart properly. Soon as I saw them being used it was a cert that the diversion was going to need refolding of the chart in the air
