First of all, toss your slide rule computer into the dustbin. And throw away all your notes. BUT make a copy of your logbook, keep that up to date as well as the original logbook. Mine was stolen, together with my car...the car came back, the logbook never did.
Second, read again what Fleet Flyer says in his post...
Practice, practice. If out of practice, have a couple of flights with an instructor to get back in the feel of it.
O yes. and if you are suddenly startled by a scary noise, do nothing at all.
Sudden reactions can make things worse; if the scenery is blue side up and green down, take time to asses the problem. A seatbelt hanging out the door can make an awful noise. Wait until later to sort it. I guess we call this suggestion don't panic. And don't hesitate to go around if it looks like a good plan. That's the plan B all you power guys enjoy. We glider pilots just have five or six places to plonk it if cows suddenly turn up where you had intended to land....Plan A, Plan B, Plan C.
And dare I say it again, learn to fly gliders. It will make you a better pilot.
