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 ...

Does Buoyant Lift Force scale with Load Factor?

Let's say I am flying an airplane that has a weight of 100,000 kg with a 1G load factor at normal steady flight. I have helium lift assist that is providing 50,000 kg (50%) worth of buoyant lift force ...

How will a prolonged series of steep turns produce a stall in subsequent level flight?

In Stick and Rudder, the author warns pilots against the unreliability of judging airspeed and hence “buoyancy” — his term for how far the airplane is from aerodynamic stall — by throttle position, ...
