From the site you quoted:

Title 15, Section 15.16.110 of the King County
code states, "Except aircraft in control of authorized maintenance
shops, no aircraft engine should be started or run unless a pilot or
mechanic is attending the controls."

It doesn't say anything about 'the beast being tied down'.

Apples and cumquats. They've tried to get through to you libertarians
that
you have to have a competent person at the controls or at least have the
beast tied down.
