Definition
The set of conditions and inputs that influence whether an airplane will stall, including angle of attack, airspeed, load factor, weight, bank angle, configuration (flaps, gear), power setting, and center of gravity. A stall occurs when the wing's angle of attack exceeds its critical value, and these factors determine how close the wing is to that limit at any given moment.
Plain English
All the things that affect how close the wing is to stalling. The biggest one is how steeply the wing is meeting the air, but bank angle, weight, how fast you're pulling back, flaps, and power all play a part too.
Context Anchor
You will see this term in discussions of stalls, unusual attitudes, and airplane upsets, especially when explaining why an airplane can stall in more than one flight condition.
Derivation
“Stall” originally means to stop or come to a standstill. In aviation, it does not mean the engine stops; it means the wing can no longer produce normal lift because the airflow over it has broken down. “Factors” are contributing things, so stall-related factors are the things that contribute to or affect that wing-stall condition.
Why Pilots Care
Identifying these factors during recovery prevents secondary stalls and loss of control.
Grounding Statement
A stall is not tied to one exact speed; it depends on what the wing is being asked to do at that moment.
Intuition Check
Do not read “stall-related” as “engine-related.” In this context, a stall is about the wing losing normal lift, not the engine quitting.
Example Sentence 1
Before practicing steep turns, the instructor reviewed the stall-related factors so the student understood why bank angle increases stall speed.
Example Sentence 2
After the unusual attitude, the pilot checked airspeed and load factor to confirm stall-related factors were no longer present.
