Without parking brakes, I'd have to use chalks.

Hydraulic parking brakes seem to work fine on aircraft ranging in size
from a PA-28 to an MD-11. I can't see any reason they could not be

Since when do you leave hydralic brakes locked on aircraft? Chock
(chalks if you prefer :-)), tie down, unlock brakes. Right?
