You can also use the flaps to "jump over" a fence or ditch
that you see at the last moment before a forced landing if
they are up for the glide.

If you have ones that react fast. I loved the "johnson-bar"
flaps in the 170's and early 172's. In the electric flapped
172's it is doubtful you could pull that manouver. The Navion
hydraulic flaps are even slower.
