Hmm... Interesting read.
I was taught by a very experienced instructor, and we practiced the crap out of glide approach. In fact, I setup for it on every landing now. Recently I have been surprised at how little is being taught to new pilots, as I was put through the ringer. We practiced engine outs every where. Take off, in the circuit, over the coast, in the middle of nowhere etc etc. I good deal of attention was given to things like side slip , and how to get down quickly if running out of room etc. Forced landings were practiced heavily away from the airfield. Short field and soft field landings etc, and then mixed it up with simulated engine failures with a short field, then a soft field etc etc etc. We called it "how not to die training"
Most of my landings are now all glide, with only a very occasional need for power if I have hit a good head wind on final. But a good look at the windsock and I can generally pre-empt that.
I also spend about 2 hours every 3 months or so going over emergency sequences again. Forced landings, stall recoveries, side slips, soft and short fields - the whole box and dice. I own the bird so the costs are low, and I like to keep my skills up, instead of just take off, cruise and land.
