Definition
A warning of an impending stall that comes from the airplane itself rather than from a stall warning device. It includes physical cues such as airframe buffet, control buffet (a shaking or stiffening of the controls), and reduced control effectiveness as the wing approaches its critical angle of attack.
Plain English
Signs the airplane gives you that it is about to stall — shaking, sloppy controls, mushy response — rather than a horn or light telling you so.
Context Anchor
Used during stall recognition and recovery training, including instrument flying, where the pilot may need to notice aircraft feel and behavior without relying only on outside visual cues.
Derivation
Aerodynamic comes from Greek aer (air) and dynamis (force or power). An aerodynamic indication is a clue produced by the way the air is flowing — or starting to break away — over the wing and control surfaces, felt directly through the airframe.
Why Pilots Care
Allows recognition of stall onset through direct feel when instruments may lag, be unreliable, or be out of view.
Grounding Statement
As the wing gets closer to a stall, the airflow can become less smooth, and the airplane may begin to shake or feel less responsive.
Intuition Check
Do not assume an aerodynamic indication means only an instrument indication. Here, it means a clue caused by airflow and aircraft behavior, not just a gauge, display, or warning horn.
Example Sentence 1
As the pilot slowed the airplane, the first aerodynamic indication of an impending stall was a light buffet through the airframe.
Example Sentence 2
In the steep turn, aerodynamic indications appeared before the airspeed indicator reached the stall warning speed.
