Could a plane be constructed to be fly in fixed-stick roll-stable circles?

According to it is not possible for a plane to aerodynamically recover from a roll disturbance. Is that an inherent limitation of how planes could be ...

Why don't we have yokes that look like steering wheels?

This question came across my mind when I was thinking about cockpit design vs car design: why don't we have yokes that look like steering wheels? The first advantage I can think of is more gestures ...

Is a monobloc variable incidence wing viable (updated)?

Could this be a viable way to control roll on an aerobatic airplane, using some sort of tab to control a monobloc variable incidence wing? Both wings are mechanically linked together in order to only ...

What makes the ailerons on an aerobatic airplane different than the ailerons on a non-aerobatic airplane?

I often hear a spec of the "roll-rate" when talking about aerobatic airplanes and the term "fast ailerons." What exactly does that mean, and what makes the ailerons on an aerobatic airplane different ...

What classes of aircraft require hydraulic flight controls?

All commercial airliners such as the Boeing 737 or Airbus A320 or heavier aircraft require an hydraulic system that can power actuators, which generate the required forces to move the control surfaces ...

What are the pros and cons of sealing the gap between the wing and the aileron?

I read somewhere that sometimes gap between the wing and aileron is sealed and this is done to reduce drag. But somewhere else I read that "slotted" ailerons allows for better aileron ...

What advantage might interplane-strut mounting offer to ailerons, on the Curtiss Model F?

Glenn Curtiss's 1912-1918 Model F biplane flying boat has large ailerons on the struts between the wings, not contiguous with any other flying surface. Did this aileron position have any advantage ...

How can I calculate the rolling moment of an aileron for a given plane based on its performance?

Let's say I have an already-built airplane with known basic characteristics like weight, wing span and wing surface, and I can measure the time of all possible manoeuvres at different speeds. How ...

Are Aircraft yokes self centering in non-auto pilot mode?

In a typical car steering wheel if you release it while the car is in motion, it will return to its center, neutral position. What's the corresponding situation in an airplane? Is a yoke self ...
