M (Horsley2016),
Those documents from the MOD which you have photographed (with your phone by the looks of it!) are next to useless (sorry!) for getting the details, like dates. Can I suggest that when you have time, you slowly re-photograph sections of each sheet, and post them up and we can try and tell you what they mean. I suggest using a warm iron to remove the creases (iron on the blank side of the paper) then put the sheet close to a window and with your phone parallel to the page photograph discrete sections. Check the images to see if you can read the text before posting as it will save time. If all this seems like too much bother, maybe you can just transcribe the bits you don't understand and we can try and expand the abbreviations and terminology.
To be honest there's wealth of information out there about the Sqdn and the operations they flew. You should be able to build a very detailed picture of his RAF career.
