How is vertical speed managed in Airliners? [duplicate]

When an Airplane starts to take off, the Horizontal velocity would generate it the necessary lift, and then Airplane pitches up to further increase the lift. As the Airplane is climbing up, the net ...

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 ...

Can I climb with no excess thrust [duplicate]

I've been searching on the internet about this question and all say you are not able to climb with no excess thrust. But I am wondering that if I have no excess thrust, can I still climb in exchange ...

Is more lift needed for a stabilized climb [duplicate]

First, the photo depicts a vector diagram during a climb. L means Lift. Lv means the vertical component of lift. Lh means the horizontal component of lift. T means Thrust. D means drag. W means weight....

Is the Lift required for a steady-state climb and descent equal for the same absolute value of the kinematic climb angle? [duplicate]

Here is my confusion : I found in my lecture script the following equation for the steady-state climb and descent (wings level) ...

Why do airplanes lift up their nose to climb?

Is it right that basically an airplane just needs to accelerate to climb? Greater velocity of an airplane leads to greater lift - and since its weight remains constant (or even decreases) - a greater ...

Can a wing generate lift in excess of its aircraft's weight?

"For a plane or bird to fly, its wings must produce enough lift to equal its weight. " I got that excerpt from "https://www.sciencelearn.org.nz/resources/300-wings-and-lift". My questions: (1) Can ...

What prevents a small plane like a Cessna or Piper from flying as high as a jet?

Obviously taking oxygen in consideration. What prevents a small plane from being able to fly at a much higher altitude? I know some business jets can fly up to 40,000 ft. Does it have to do with the ...

Is excess lift or excess power needed for a climb?

As answered in this question, aircraft need excess power - not excess lift - to climb. This is plausible when the aircraft's thrust vector has a vertical component (its nose and engine points upwards),...

How does an aircraft descend without its nose pointing down?

I have seen many cockpit videos of airplanes landing, and nearly none of them have their nose down for losing altitude. How does this happen? and how does an airplane, such as A320, descend without ...

Airplane longitudinal control: pitch or power?

I recently came across some slides from a flight school teaching, for the initial climb after take-off and for the approach, the strategy of controlling/adjusting RoC/RoD with power Speed with ...

Why is lift larger than thrust? [duplicate]

It's been a while since I tried to read a little about flight mechanics and aerodynamics, but I remember one question I had back then: Is the thrust of a common passenger aircraft (A320, B737) ...

Does lift equal weight in level flight?

Does lift equal weight in level flight? Or does it equal weight + down pressure on the tail? Added) Let's say the total weight of the aircraft on the ground was 100,000 lbs, and when it took off and ...

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 ...
