Is there always a stall if you exceed a specific angle of attack?

So lets consider that the stall angle (=Cl max) of a B747 is at 16° (in clean configuration). Does this mean, that, at whatever speed you are flying (i.e. 500 knots), you would stall if you go on a ...

Does adding high thrust prevent a plane from stalling?

I am convinced that fighter jets (every flying object) do stall. So from quora, Why don't fighter jets stall? But most of the fighters have thrust:Weight ratio > 1 which means that they are not ...

What does the pressure distribution over a glider's wing look like?

Can someone explain the design of glider wing airfoils and the subsequent pressure distribution over them? I hypothesize that: The pressure distribution should form a resultant force in the forward, ...

What produces thrust along the line of flight in a glider?

After reviewing discussions and vector diagrams of gliders in flight, the vertical lift component and the vertical drag components seem to produce a steady state, 0 acceleration balance with gravity. ...

What happens at the wings when the yoke is pulled backwards?

What happens at the wings and vertical stabilizers when the yoke is pulled backwards or forward on typical airliners like the Boeing 747-800. Is it any different for smaller similarly shaped aircraft ...

Can a plane still climb even if it has exceeded the critical AoA?

According to this answer here, an airplane requires less lift for a climb than horizontal flight because the thrust of the engines will point up. Now if the wing was in a stall condition, could the ...

Can this vane prevent/delay wing stall?

Given that a stall results from the airflow over the top of the wing separating from the wing at high angles of attack, would it be possible to prevent, or at least ameliorate, a stall by deflecting ...

Is all the extra lift from flaps added upstream where the spars sit?

Flaps can significantly increase the lift for a wing, is all that extra lift added upstream where the spars sit? I ask this question because the flaps in airliners seem to be only connected by a few ...

How does angle of attack vary during climbing flight?

I'm a little confused by the angle of attack of an aircraft during climbing flight. Suppose you have an aircraft in level flight which then rotates to some angle x. Just after rotation, I would assume ...

Can plane climb without increase pitch angle?

As I know plane climb "with nose up", but can plane climb without change pitch angle? Can I force plane to climb like this: If I fly in straight level flight at 100km/h and now increase ...

How to calculate the lift starting from the vertical speed?

Is it possible to calculate the lift of an aircraft knowing its speed (IAS,TAS and GS), its vertical speed, its altitude and its weight? Because if we look at the force of an aircraft in flight: the ...

Does angle of attack change in a sustained climb?

I saw this question on a closed Facebook group, generating wildly differing answers. So I thought I would ask it here. You're in a C172 flying straight and level at 5000 feet and 100 knots IAS. You ...
