60,
In my time the pilot flying announced his intentions and called for clearance by the crew before moving the aircraft and received notice from the crew that all was clear in all directions...including upwards...before initiating the movement.
Should your Pilots be falling short in following your Unit SOP's.....take it up with the Unit Safety Officer in a discrete manner as possible.
Holding your peace and going along for the ride carries far more risk over time than having that chat with the ASO.
Aviation Safety Meetings are supposed be occasions such concerns can be brought up and be formally addressed.
Likewise, periodic review of SOP's to ensure they include "Best Practice" procedures should also be done as part of the Unit Safety Program.
One method for that is to do an Audit....take the SOP as written and interview Flight Crews or Maintenance Crews to see if the printed SOP is exactly how business is conducted on a day to day basis and if a difference is noted....determine which is the better method....the written one or the one being used.....and make sure the best one becomes the written one in the SOP.
Safety is an All Hands effort with no Sacred Cows.
