Weird signs at terminal

[anthony]

Im not very good at taking screenshots but My park me signs when pulling into the terminal look weird. Number one they are yellow with a picture of an airplane. No lights on them at all. Not sure what this means.

Thank You
Anthony

You are probably referring to the optical docking systems, that's exactly how they are in reality, they work by parallax effect, without any lights or electronics.

The manual contains all of the information that you could want about the Safedock system, including pictures of the various indications that you'll see. See pages 6 through 8.
