Standard Operating Procedures (SOPs) are written policies and practices designed to ensure operational consistency and reduce errors. They encompass normal, abnormal, non-normal, and emergency operations to produce predictable and safe outcomes in all phases of flight.
SOPs = Doing it the right way, all the time, every time.
Each SOP provides a structured approach to tasks in all flight phases, detailing what needs to be done, when it should be done, and who is responsible for its execution.
SOPs should be adapted to align with specific equipment and the individual pilot, instructor, or flight school. They can be structured around five key areas that cover all phases of flight: Plan, Brief, Do, Review, and Renew.
Effective automation management allows the pilot to assess, detect, and correct errors; thus, it helps prevent accidents.
While there is no industry consensus, the levels of automation can be defined as:
No one level of automation is appropriate for all flight situations.
Workload typically decreases at higher levels of automation. However, there are times when manually flying can be more beneficial. Pilots should consider stepping down a level in automation when necessary.
The underuse of automation can lead to errors resulting from the increased workload.
Common errors of automation underuse include:
The overuse of automation can lead to complacency and degraded hand-flying competence and confidence. Pilots should regularly fly the aircraft manually to maintain stick-and-rudder proficiency.
Common errors of automation overuse include:
Automation should be managed actively rather than passively (“set and forget”). Active automation management enhances situational awareness and helps to identify automation failures.
To actively manage the automation, pilots must:
Managing the autopilot means knowing which modes are engaged and which are armed to engage.
Autopilot management errors can be reduced by:
Caution: Anytime the autopilot is disconnected, the pilot should have a firm grip on the controls to counter any unexpected trim forces.
Humans are not well suited for monitoring automated systems. Extended periods of performing trivial tasks often lead to daydreaming or complacency.
Monitoring errors can be reduced by:
Effective task management ensures that essential operations are accomplished without overloading the pilot.
Task saturation occurs when the demands of a task exceed the pilot’s capacity to manage them, leading to lost situational awareness and increased risk of error. Effective task management helps pilots prioritize and complete tasks without overload.
Accidents often occur when flying task requirements exceed the pilot’s capabilities. The difference between these two factors is called the margin of safety.
The highest task requirements typically occur during the approach and landing phase. At the same time, the pilot’s capabilities may deteriorate due to fatigue or distractions.
Multitasking is the simultaneous execution of two or more tasks. It involves two different abilities: attention switching and simultaneous performance.
Attention switching is the continuous switching of attention back and forth between two or more tasks.
Simultaneous performance, or performing several tasks at once, is possible when skills develop to the point of being automatic.
Processing Power: Multitasking comes from a computer’s ability to execute tasks simultaneously. But humans are not computers. Human multitasking involves constant micro-interruptions and “stop-go” decisions, all of which reduce mental and motor performance.
Lack of Experience: Inexperience with a task can often hinder attempts to combine it with other tasks. New skills should be developed in isolation.
Exclusion: It isn’t easy to perform more than one task that requires cognitive effort. Attention is often devoted to comprehending one to the exclusion of the other.
Diminished Quality: When workload increases, the typical response is to reduce standards for quality and achievement.
Distractions occur when an unexpected event momentarily diverts attention. Pilots must learn to decide whether a distraction warrants further attention or action.
Interruptions occur when a pilot voluntarily stops performing one task to complete a different one. If the original task is not resumed correctly, this can lead to an error.
Fixation occurs when a pilot becomes absorbed in performing one task to the exclusion of other tasks. Fixation on a task often indicates that the task has not received enough practice in isolation.
Inattention occurs when a pilot ignores an important task. It is sometimes a by-product of fixation.
Complacency is overconfidence that results from repeated experience with an activity. It is an insidious and hard-to-identify attitude.
Information management is the ability to monitor, manage, and prioritize a continuous flow of information to accomplish specific tasks. Proper information management reduces pilot workload, enhances situational awareness, and increases navigational accuracy.
A place for everything and everything in its place.
Benjamin Franklin
Before starting the engine, items should be arranged to be secure and accessible. Essential equipment should be within easy reach.
These seemingly small actions can reduce workload and enhance safety. Since everyone has a different way of organizing themselves, the optimal arrangement comes through experimentation.
A clear understanding of who has control of the aircraft must exist. Prior to flight, the pilots involved should conduct a briefing that includes reviewing the procedures for exchanging flight controls.
A recommended three-step process of exchange includes:
The preflight briefing should include a method for relinquishing and taking control of the aircraft when normal communications are not possible (e.g., intercom failure) and it should set the expectations in the event of an emergency situation.
Commonly known as the sterile cockpit rule, air carrier pilots must refrain from nonessential activities during critical phases of flight.
Critical phases of flight are all ground operations involving taxi, takeoff, and landing, and all other flight operations below 10,000′ except cruise flight. Nonessential activities include things like eating or chatting.
The equivalent sterile cockpit altitude for light aircraft can be defined as 2,500′ AGL or at any altitude within 10 minutes of landing.
Checklists act as a systematic guide, ensuring that all procedures are carried out in the correct sequence and nothing is omitted. Furthermore, they standardize flight operations, thereby minimizing the chances of human error.
Many checklists differentiate the performance of checklist items by using the terms “pilot flying” (PF) and “pilot monitoring/pilot not flying” (PM/PNF) to avoid confusion. The PF refers to the pilot manipulating the controls, regardless of which seat he or she occupies.
The proper use of a checklist depends on the task being conducted. In some situations, using the checklist would be unsafe or impractical, especially in a single-pilot operation. In this case, reviewing the checklist after the elements have been accomplished would be appropriate.
Challenge-And-Response (Do-List): A typical checklist has two columns. The left column shows the switch or control that needs to be moved or verified (the challenge), and the right column shows the action that needs to be taken with the switch or control (the response). Each challenge is read and is followed by the necessary task or check being accomplished. A response is made only after verifying the proper configuration or condition exists.
Flow (Do-Verify): A mental “flow” check can be used in high workload situations. The flow is a systematic scan of the instrument panel. It shows the pilot what items to consider, not what to do. After completing the flow, the checklist is read to verify that all items have been completed.
Pilots may purchase or adapt checklists to streamline operations and incorporate personal preferences. Any changes must be thoroughly reviewed to ensure they align with the manufacturer’s recommendations and aircraft limitations.
Adapting emergency checklists is generally not recommended due to the critical nature of these procedures. Improperly adapted checklists can lead to missed steps, procedural errors, and reduced safety margins during critical situations.
The PIC is required to:
Elements of a passenger “SAFETY” briefing:
Other items to consider:
Crew resource management (CRM) applies team management and SRM concepts in a flight deck environment. The “crew” encompasses anyone working with the flight crew, including dispatchers, cabin crew, maintenance personnel, and ATC.
The key to crew coordination is "saying the right thing, to the right person, at the right time, in the right way."
Before any flight, the PIC should conduct a crew resource management (CRM) briefing to establish open communications, teamwork, and crew coordination.
Elements of a CRM briefing:
At any point during a flight, one pilot is flying, and one pilot is monitoring.
The pilot flying (PF):
The pilot monitoring (PM):
If the PF needs to engage in activities that would distract from aircraft control, the PF should transfer aircraft control to the other pilot and assume the PM role.
The two-challenge rule is an intervention policy that allows one pilot to automatically assume the duties of another pilot if he or she fails to react after two consecutive challenges. The failure to respond could be confusion, task saturation, or incapacitation.
Example:
Beginning and Ending a Checklist: State the name of the checklist before beginning. Conclude by stating the name of the checklist and affirming “checklist complete.”
Interrupted Checklists: If the checklist is only delayed for a brief period and the pilot is sure of where he or she was interrupted, the item may be completed, and the checklist may continue. Otherwise, restarting the checklist from the beginning is recommended.
Touch Verification: Enhance accuracy by physically touching each gauge, switch, or control when verifying items. This method minimizes the risk of false confirmations.
Single-Pilot Operations:
Two-Pilot Operations:
Emergencies: Use the challenge-and-response method for non-normal and emergency checklists to ensure a methodical approach and reduce the risk of errors during critical situations.
