In the mid 1950s the RAF basic flying syllabus on the Provost contained two sorts of forced landing, FL with or without power IIRC they were listed as ex 17a&b. 17a was also known as the "Precautionary Landing", the procedure was intended to achieve a safe off-airfield landing if one was caught out by bad weather or lack of fuel/daylight or whatever. It included finding a suitable field, flying a low-level circuit and approach to inspect the surface followed by another low level circuit and short-field landing.
In the 1980s at Scone the CAA basic syllabus featured the same exercise, perhaps it still does?
