A few points for an arriving aircraft.
.
1/ Stand should be empty inside the lines and no FOD.
2/ Emerg Stop button should have a person in position.
3/ Chox fitted in a correct fashion when engines and lites off.
4/ Pilots advised Chox fitted.
.
It appears that the above is rare, the rule book seems to get red just after a person is hurt or aircraft gets damage, the book then gets put away.???
