Dual Trim Switches?

For what it's worth.

When I first checked out in an SP, the CFI told me Cessna had been
sucessfully sued when a pilot argued the tanks could not be sumped correctly
unless the aircraft was parked perfectly level.

Now you can drain the lowest point in the tank, no mater how or where you
park your SP.

I would tend to doubt that version of events. The 13 drain points were
introduced when Cessna restarted production on the redesigned 172R back in
'96. The drains were in the new version from the start, so I doubt Cessna
could have been sued. Also, we probably would have heard about it here.

Previous versions of the 172 ('84/'85) had wing tanks with no obstructions
in the bottoms. The new version had wet wings, which is what prompted the
installation of drains outboard of each rib in the tank area.
