I am doing prec search and land this Friday as part of my training (in Aus). My understanding is we do it at the airstrip so its legal.
Re Forced landings, I have already done that. It is done in the training area and you are taught how to pick a suitable landing area and the tricks to make it a successful land. Once at 500' (on final) you know damn well if you are too low/high and if it will be a successful land.
As a student now, when coming into land from the training area I always do a normal approach with a touch and go, then go around to do a simulated forced land or a flapless approach etc. Keeps the skills up. After friday, I will also add in a prec search and land to that process.
