- Question & Answer
How does stall depend on angle of attack but not speed?
The stall Angle of Attack (AoA) is not fixed, but increases with pitch rate and - to a lesser extent - with the Reynolds Number. When a wing stalls, the boundary layer in the rear part of a wing stops and even reverses it's flow direction, causing separation .

Aerodynamics: Nothing but a number - AOPA
Mar 1, 2020 · Factors such as total weight, load factor, power, and center of gravity location affect stall speed—sometimes significantly. Stall speed increases as weight increases, since wings need to fly at a higher angle of attack to …
Aerodynamics & Performance - Stall Performance - CFI Notebook
Stalls are ultimately brought on by exceeding the critical angle of attack; A stall is, therefore, an aerodynamic condition in which the Angle of Attack (AoA) becomes so steep that air can no …
Understanding the Dynamics of an Airplane Stall
In aviation, a stall is a condition in aerodynamics where an increase in the angle of attack leads to a reduction in the lift coefficient. This occurs when the critical angle of attack is exceeded, resulting in the airflow separating from the upper …
At What Angle Of Attack Will An Airplane Stall?
Mar 13, 2024 · Most civilian planes will stall at an angle of attack between 15 and 20 degrees, while fighter jets can fly up to 40 degrees before they exceed their critical angle. Every aerodynamic surface that provides a lift vector has a …
The Right Formula - AOPA
Nov 1, 2017 · Because stalls depend on angle of attack—the angle between the wing chord and relative wind—they can occur at any airspeed, at any attitude, and at any power setting. …
Stall (fluid dynamics) - Wikipedia
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value. [1] . The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil – …
4: Performance in Straight and Level Flight
We define the stall angle of attack as the angle where the lift coefficient reaches a maximum, CLmax, and use this value of lift coefficient to calculate a stall speed for straight and level flight. Note that the stall speed will depend on a number …
What Is a Stall Speed and How Does It Affect Airplanes?
Jul 29, 2020 · Stall speeds vary depending on many factors, some of which include the airplane’s weight, dimensions, altitude and even the weather dimensions. Regardless, airplanes must fly …
Mastering the Skies: Navigating the Critical Dynamics …
It refers to the angle between the chord line of the wing and the oncoming air. As the AoA increases, so does the lift, up to a point. Beyond this critical angle, lift begins to decrease, leading to a stall.
Stall - SKYbrary Aviation Safety
A stall occurs when the angle of attack of an aerofoil exceeds the value which creates maximum lift as a consequence of airflow across it. This angle varies very little in response to the cross …
Why Does Stall Speed Increase With Bank Angle? - Boldmethod
Nov 14, 2023 · You increase your total lift by increasing your angle of attack, which means you're closer to stall than you were in wings-level flight. And, your stall speed increases in proportion …
Stalling & Spinning – Introduction to Aerospace Flight Vehicles
The highest angle of attack that a wing can operate is called the stall angle of attack (or the stall angle) and corresponds to the angle to the flow when flow separation progresses to the point …
Under what conditions do airplanes stall? [duplicate]
Dec 8, 2022 · Stall is defined as the point where the lift curve slope over angle of attack becomes flat or the lift coefficient peaks. It is caused by progressive flow separation on the suction side …
What is a Stall? - When Wings Stop Working - Pilot Institute
Apr 11, 2022 · In general terms, a stall is when an aircraft wing stops producing lift due to an excessive angle of attack. The angle of attack is the angle between the wings cord line and the …
Is there always a stall if you exceed a specific angle of attack?
Apr 20, 2015 · Up to stall, lift depends approximately linearly on angle of attack and square of speed (and on air density). In straight flight the forces on the aircraft need to be balanced, so …
Stall Angle - an overview | ScienceDirect Topics
Precise estimation of maximum lift with a stall angle of a wing is an important issue for the aerodynamic design of aircraft. It is important and necessary to develop a prediction method of …
