I was watching a video of
at ramp and the chocks used seem tiny especially in front of that monster plane. (shown at minutes 3:10-3:25 in video)
Can chocks so small stop a plane that heavy. Curious how the chock sizes are mandated; what's the physics behind this?
Do ground handlers use different chock sizes for larger planes? Also what is the mode of failure chocks are designed to protect against; wind induced movements, I suppose or maybe gravity? If an engine or tug were to accidentally try to move an aircraft would the chocks do much?
