STANDARD OPERATING PROCEDURES (SOPs)
Standard Operating Procedures (SOPs) fall into two categories, the first of which identifies a core of mandatory actions or procedures that must always be performed because the failure to do so has a direct adverse impact on the safety of operation. These SOPs include formal items such as Standard Call-outs, altimeter setting and checking procedures, emergency drills, and non-exceedance of limitations.

The second category of standard operating procedure has the purpose of standardising procedures to make it possible to crew any two Flight Crew members together on a non-regular basis without lowering safety standards. The consequential requirement is that personal methods or practices shall not be introduced.

The bottom line is: SOPs provide for enhanced morale between crew members that is often caused by doing things differently. For pilots who are in training, or new to the company, they will help to ensure faster integration. SOPs provide a shared reference framework for all crew members and promote crew synergy.

"Undesired aircraft states leading to threats can be prevented by consequently applying automation as directed per SOP." Incorrect. The use of autopilot/autothrust increases passenger comfort, however it does not automatically prevent undesired aircraft states.

"Pilots not applying SOP can immediately be reported and excluded from flying duties to increase flight safety." Incorrect. A significant number of operating practices actually allow the discretion to the commander to decide how the flight should be flown. Of course, these are characterised with the need to exercise sound judgement and prudent assessment.

"SOP can only help to reduce the rate of systematic errors, random errors cannot be prevented." Incorrect. SOPs can reduce the rate of systematic errors as well as random errors.
