### How does aircraft weight affect the glide performance? [duplicate]

Since the L/D ratio remains unaffected by the aircraft weight, will there be any effect to the gliding range?

### How far can airplanes glide?

On an another question, an answer said: You don't need an engine to fly as airplanes are designed to glide without it. I suspect this heavily depends on the type of the aircraft, so lets assume we ...

### What determines the best glide speed?

I found the best glide speed of cessna 152 is 60 kts. My question is why it is not more or less than 60 kts? What are the factors upon which the best gliding speed is determined?

### What is the weight that is used to balance an aircraft called?

I remember I was reading about balancing an airplane a few days ago, and i came across a type of weight that is added to balance the airplane. But, I do not remember what it was called. Also could ...

### How are the glide polar and L/D ratio charts related?

We know from other questions and answers that airplanes and gliders in particular can have their performance described in terms of glide polar and Lift-to-Drag ratio. As it appears from the images in ...

### What does this statement about steep descent mean?

Source: Wolfgang Langewiesche - Stick and Rudder; An Explanation of the Art of Flying In the first chapter the author mentions, in a glide, if you want to descend more steeply, you want to want to ...

### Is (L/D)max achieved at a specific speed or AOA?

I'm little bit confused about the (L/D)max. So I've read this blog: https://joeclarksblog.com/?p=4155 and the author shows this graph: So if I understand it ...

### Does lift-to-drag vary with anything beyond geometry?

The basic equations for both lift and drag show dependency on $v^2$, air density and some constants. At a glance, Lift to Drag ratio should depend on nothing else than plane geometry. Although I ...

### Could the wing struts on the SUGARVolt cause problems?

On Boeing's concept aircraft, the SUGARVolt, there are wing struts connecting the fuselage and the wings, which is for making sure that the wings do not bend too much during flight. Could the wing ...

### Would all these three things have the exact same effect on the flight duration of a glider?

Consider a glider trimmed to fly at some given angle-of-attack, gliding in smooth air (no thermal convection, ridge lift, wave lift, etc.). If air density is somehow kept exactly constant in all ...
