阅读下列文章,结合个人理解,回答相关问题。 Standard Operating Procedures (SOP) ( 标准操作程序 ) Standard Operating Procedures (SOPs) are designed to enhance safety, to assist the flight crews to manage risk and to ensure consistency in the cockpit. Consider them guidelines as to who-does-what-and-when. At all times, these procedures should encourage effective communication and teamwork in the cockpit. SOPs can be either general in nature or aircraft specific. Although aviation companies have a certain amount of latitude( 纬度 ; 自由 ) when creating their SOPs, under no circumstances should they violate ( 违背 ) aviation regulations or the procedures outlined in the aircraft flight manuals( 手册 ). Included in the SOPs should be a section on normal procedures, and it is to be considered an enhancement of the aircraft flight manual. These normal procedures include all aspects of day-to-day flight, including the start-up and normal procedures checklist, the take-off briefing, go-around( 复飞 ) procedures, IFR approaches, etc. A section of the SOPs should be dedicated to emergency procedures, with the expanded version of the emergency procedures checklists. Again, this should compliment the aircraft flight manual's emergency section and streamline procedures removing any ambiguity ( 模糊不清 ). Another section can include aircraft landing and take off distances charts, a JBI chart, or any other references that the flight crews may require. SOPs should be reviewed periodically and amended to maintain their relevance in changing times or aircraft fleet( 机队 ). Care should be taken not to include non-applicable items, as personnel may then tend to view the whole package as being irrelevant. SOPs should be written in terminology( 术语 ) leaving no room for subjective interpretation. There are definite safety benefits from the use of Standard Operating Procedures but they must first be adopted by the flight crews. Company check pilots should monitor for crew adherence to the SOPs. Finally, there is no substitute for good judgment, and decisions made in the cockpit should be supported by management.
