Lesson 8.2 Human Factors & Pilot Error

Lesson 8.2 – Human Factors, Pilot Error & CRM/SRM

Most aviation accidents involve some form of human error. Understanding human factors and applying Crew Resource Management (CRM) / Single-Pilot Resource Management (SRM) principles helps pilots recognize and reduce those errors. These topics appear regularly on the Private Pilot knowledge exam.

Human Factors

Human factors is the study of how pilots interact with the aircraft, the environment, procedures, and other people. It focuses on human capabilities and limitations and how those limitations affect safety.

Common human-factor problems tested on the knowledge exam:

• Fatigue

• Stress

• Distraction and channelized attention

• Complacency

• Loss of situational awareness

• Workload overload

• Poor communication

The Error Chain

Accidents rarely result from a single mistake. They usually develop from a chain of events and decisions. Breaking any link in the chain can prevent the accident. Effective ADM and CRM/SRM are designed to interrupt the error chain early.

Crew Resource Management (CRM) & Single-Pilot Resource Management (SRM)

CRM was developed for multi-crew airline operations. The same principles apply to single-pilot flying and are called Single-Pilot Resource Management (SRM).

Key CRM/SRM principles that appear on the test:

• Use all available resources (ATC, Flight Service, checklists, automation, aircraft systems, passengers when appropriate, and your own knowledge and judgment).

• Maintain situational awareness at all times.

• Manage workload — prioritize tasks and avoid becoming overloaded.

• Communicate clearly and assertively when needed.

• Make decisions early, while options still exist.

• Continuously evaluate whether the current plan is still safe.

Even when flying alone, you are still managing a “crew” of resources. Failing to use available resources is a common human-factor failure.

Practical Defenses

• Use checklists every time.

• Apply PAVE and IMSAFE before flight.

• Set and respect personal minimums.

• Recognize fatigue, stress, or distraction early and adjust or cancel the flight.

• Actively work to maintain situational awareness.

• Resist external pressures (“get-there-itis”).
