Backup for dropping the gear

I'm not sure there's enough standardization in gear retraction/extension
systems to say what's "normal". However, certainly the lack of redundancy
is common enough on light planes. In fact, not only is the gear on my
airplane designed similarly, the flaps and elevator trim use the same
hydraulic system. A failure in the hydraulic system that takes out
certain
lines, and/or results in a loss of fluid would affect all three systems
simultaneously.


I suppose you could also run the brakes off the same hydraulic system as the
gear, too. After all, if the gear fails you won't be needing any brakes. :-)
