I wonder what training is given to power pilots for selection of fields for a forced landing. I was already an experienced glider pilot when I did my PPL, and had landed in more fields than any of my power instructors. I had almost no instruction at all in the power world, probably because of my gliding experience. I was able to just pick a field and set up a suitable approach without difficulty.
In gliding, the basic instruction given to would-be cross-country pilots is to be within reach of landable fields at 2000 feet, start choosing fields at 1500 feet, and at 1000 feet, forget about trying to stay up and concentrate on assessing the chosen field and setting up a good circuit for a stable approach. With the relatively low sink rate of a glider, compared with a powered aircraft with engine failure, there is ample time to do this. Hence there is rarely any damage to the glider in a field landing.
One reason for not picking the field until down to 1500 feet is that above that height it is difficult if not impossible to see slope, obstructions such as power cables, etc.
In a powered aircraft, with a much higher sink rate, and a considerable level of stress and workload combined after engine failure in cruise, the field choices are very limited, and I would expect a significantly higher proportion of at least some damage to the aircraft.
But you guys (some of you) on here are the experts on powered aircraft forced landings, so I defer to your greater experience of power PFLs.
