How to secure an aircraft at a transient parking space? 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.
Tie downs are generally for overnight or longer.   Nobody ties down an airplane for a visit of a few hours unless there is something forecast in that few hours like high winds or thunderstorms.  And if that's the case, you will want move it somewhere on the airport that has unused permanent tie downs or inside a hangar for the duration of the weather event.

Most screw or spike-in grass anchor systems are useless for serious winds and are easily pulled out.  There are several Youtube videos that demonstrate how ineffective they are, with the exception of one system that uses large spade like blades driven into the ground.
