Daily Aviation learning cards
Safety, flight & human factors. Explore a short explanation, an everyday example and a question you can answer from memory.
The Aviation collection currently has 8 written cards. The daily app introduces written ideas and revisits earlier cards once the collection is complete. Source previews offer additional reading.
Flight is a balance of forces
Lift, weight, thrust and drag act on an aircraft.
The wing's angle is relative to the airflow
Angle of attack is the angle between the wing chord and relative airflow.
A stall is an airflow problem
An aerodynamic stall occurs when a wing exceeds its critical angle of attack.
Moving through air has a cost
Drag is an aerodynamic force opposing motion relative to the air.
A checklist supports memory
A checklist helps verify important actions in a repeatable way.
Safety improves when resources work together
Resource management coordinates people, information and available tools.
Hotter air can change performance
Density altitude expresses air density as an equivalent altitude in a standard atmosphere.
