Came across this on an FAA publication dated 3/12/
Post# of 41413
" 4) A test method referred to as a “platform” or “ramp” test has also been used to assess the crew's ability to manage flow of passengers for a given interior configuration. Appropriate test conditions and pass/fail criterion need to be discussed with and agreed to by the FAA for each new situation."
