Definition
The pilot's accurate, real-time understanding of which operating mode the aircraft's automated flight systems (autopilot, flight director, autothrottle, and flight management system) are currently in, what those modes are commanding the aircraft to do, and what they will do next.
Plain English
Knowing exactly what the autopilot and related automated systems are doing right now, and what they are about to do, so the pilot is never surprised by the aircraft's behaviour.
Context Anchor
Used in aircraft with automated systems, especially when checking the flight display, autopilot settings, or navigation equipment during instrument flying.
Derivation
Mode' here refers to the specific operating state of an automated system (for example, heading hold, altitude capture, vertical speed, approach). 'Awareness' means active, current knowledge of that state. The phrase emerged from human factors research in the 1980s and 1990s, when 'automation surprise' accidents revealed that pilots were sometimes unsure which mode their aircraft was actually flying in.
Why Pilots Care
Loss of mode awareness is a leading factor in automation-related incidents and altitude deviations.
Analogy
Like knowing whether your car's adaptive cruise is holding speed or following the car ahead.
Grounding Statement
Mode awareness is the habit of checking what the system says it is doing and confirming that the airplane is actually doing that.
Intuition Check
Do not assume mode awareness means simply knowing the autopilot is on. It means knowing the exact active or next-ready mode and the aircraft behavior that mode will produce.
Example Sentence 1
After selecting the approach, the captain called out the mode changes on the flight mode display to maintain mode awareness.
Example Sentence 2
During the approach the pilot lost mode awareness when the autopilot switched to approach mode without announcement.
