FAA's Airplane Flying Handbook says more lift is necessary during a climb. Isn't it the opposite? [duplicate]

"If a climb is started from cruise flight, the airspeed gradually decreases is the airplane enters a stabilized climb attitude. The thrust required to maintain straight-and-leve flight at a given ...

Under what conditions do airplanes stall? [duplicate]

I've seen somewhat conflicting information on when planes stall. I've seen references to "stall speed," apparently a speed below which the airplane will stall, but stalling also seems to be ...

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 ...

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 ...

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 ...

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 ...

Can one trim same AOA at a higher airspeed to climb? [closed]

There has been some discussion in recent questions regarding climbing technique and optimization of the Lift vector (and the resultant vertical Lift vector). Some writers claim the lift vector must ...

How can lift be less than thrust that is less than weight? [duplicate]

Physics in schools teaches two contradictory and mutually exclusive things: That the upward lift force on an airplane in flight equal its weight (Lift = Weight = Mass x Gravity). This is based on ...

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 ...

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. ...

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 ...

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 ...

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, ...

Does lift equal weight in a climb?

This subject keeps coming up in the discussions and questions such as this one, which asks if lift equals weight in level flight. Good answers there, pointing out that upwards force has many sources. ...
