Guppy,
the military flies very few light piston singles, and most military pilots have never flown a piston airplane.
Every RAF pilot whether fast jet, multi-engine or rotary wing begins his training on light, single engine piston aerolanes. The same is true for most other air forces, and I thought that included your own. Probably 10% of the RAF's fleet consists of aircraft in this class.
I think you may be trying to skew the facts to prove a 'civvy is best' point. The fact is that the constant sightline angle technique taught by the RAF is a very effective technique for judging engine off landings in any class of aircraft, and more likely to end with a good result than the technique taught during my PPL. Yes, most military have better currency than most civvy pilots but I think the stats do make a valid point. There have been a sufficient number of successful forced landings by military aircraft over the years for the results to be statistically significant and I think you'll find that when discussing successful forced landings we are not going to be including ejections and bail outs.
When was the last time the military trained a student to actually land on a country road or in a field?
Every RAF student trains for off airfield forced landings ad nauseam during Elementary Flying Training. If you fly helicopters you never stop practising engine off landings, and the constant sightline angle technique works as well for a 24 ton Chinook in autorotation as it does for a C152.
