### What is the relationship between pitch rate, airspeed, and normal G's?

What equation defines the relationship between pitch rate, airspeed, and normal G's? I suppose flight path angle could be used here too. For example, given I'm currently at 5 degrees of pitch and ...

### How to calculate bending moments and shear forces on a wing?

I am trying to create a MATLAB script to plot the Bending Moment Diagram (BMD) and Shear Force Diagram (SFD) as a function of spanwise distance, x, along a wing from the wing root (x=0) to the wingtip ...

### When is lift greater than weight? [duplicate]

I am wondering in which phases of flight or manouevres lift is greater than weight. I know that this happens during turns and when affected by gusts but when else? During steady level flight lift ...

### What are the load factor limits of an aerobatic aircraft with a wing walker?

Wing walking seems to be performed with aerobatic planes since wing walkers making figure while the aircraft is in a looping is not uncommon, as seen in this video on the youtube FAI Air Sports ...

### How does the load factor vary when the aircraft pitches up/down?

I know that when an aircraft starts rolling, it's load factor increases. But can anybody explain how does load factor vary when the aircraft pitches up/down? Does it increase/decrease?

### Why do non-aerobatic aircraft have a negative G limit?

Why do airplane wings have limit load of both positive and negative g's (e.g., the Weedhopper ultralight has a load factor of +5 and -2gs). Why not just have a positive limit load since most airplanes ...

### What is the effect of the Load Factor on wing Structures?

I am quite confused with the definition of Load factor and how it applies to the wing structures of an aircraft. For example, you have an Aircraft being subjected to a Load Factor of 2 and whose ...

### Is there an increased concern for stall safety in a 1G steep turn?

Most people know the standard, "At a 60 degree bank, an aircraft experiences 2G's" checkpoint for load-factor on an airplane. I assume that this statement has an underlying, unspoken assumption that ...

### Why do aircraft have a crossover airspeed, and why does it increase at higher vertical load factors?

According to the NTSB accident report on the crash of USAir Flight 427, all commercial aircraft have a crossover speed (the speed at which the maximum rolling force from the aircraft’s ailerons and ...
