I've noticed that at many airports, the transient GA parking spaces often don't have tie-down anchors (e.g. bolts drilled into the pavement; heavy steel cables, etc.) or tie-down ropes. They simply have a "T" painted on the ground to indicate the parking alignment. This is true even for many FBO-managed parking spaces.
How should I secure my airplane at these parking spaces? Even if I had my own tie-down ropes, there's nothing to attach the ropes to.
I'm hesitant to just chock the wheels, as this does not prevent a gust of wind from blowing the aircraft around.
Should I ask if there's a patch of grass and use an artificial temporary anchor/Klaw system? Is this even commonly available at your average GA airport?
Note: I only need to park the plane for a few hours, not overnight.
