Aviation knowledge, clearly explained.

Aerodynamic Stall

An aerodynamic stall occurs when a wing's angle of attack exceeds its critical value, causing airflow to separate from the upper surface and lift to drop sharply. It can happen at any speed and in any aircraft attitude.

AFM/POH

The Aircraft Flight Manual (AFM) and Pilot's Operating Handbook (POH) are manufacturer-approved documents containing performance data, limitations, and procedures required to operate a specific aircraft safely and legally.

Aileron

Ailerons are movable control surfaces on aircraft wings that control roll. The pilot deflects them to bank the aircraft left or right, with each aileron moving in the opposite direction to create differential lift.

Air Mass

A large body of air with roughly uniform temperature and humidity that forms when air stagnates over a region long enough to adopt that area's surface characteristics.

Air Traffic Control

Air Traffic Control (ATC) is a ground-based service that directs aircraft movement and maintains safe separation in the air and on airport surfaces through radar, radio communication, and standardized procedures.

Air Traffic Control Restriction

An Air Traffic Control restriction is a mandatory directive issued by air traffic management to manage safe and efficient flow of aircraft through airspace. These restrictions delay, reroute, or ground flights independently of airline decisions.

Aircraft Control Surface

A control surface is a movable panel on an aircraft's wings or tail that deflects into the airflow to change aerodynamic forces and control the aircraft's attitude, roll, pitch, or yaw.

Aircraft Engineering

Aircraft engineering is the discipline of designing, building, and maintaining aircraft by integrating aerodynamics, structures, materials, and systems to meet safety and regulatory standards.
