A new or modified procedure is a coordinated effort among many groups, such as airports, air traffic control, local communities, and local aircraft operators, each of whom may have input into the final procedure. Once a procedure is developed and everyone is as happy as theyre going to get with it, the procedure is sent through a quality assurance review process. This process essentially rebuilds the procedure to verify criteria compliance, use of correct data, and proper documentation. Once past quality assurance, the next step in procedure approval is performing a flight inspection to look for anything unsafe or unexpected on the procedure that wouldnt have been known during the design process.
