A question about dead-band has been posted previously by the OP. That one was about a deadband in response of the flight controls with hydraulic systems OFF, this present question is about a deadband …

The Sikorsky UH-60 (S-70) has a tail rotor that is canted 20 degrees upwards. Why is that? Picture source

A220 cockpit Image source A320Neo cockpit Image source The Airbus A220 started life as the Bombardier C-series, with the two companies starting a partnership in 2018. An article about the C-series fli …

Reconfigurable flight control systems have been a topic of research in military aircraft for decades. The science is existing and mature, but not an easy one: damage cannot be predefined, and therefor …

The stick does not need to move in order for the pilots to sense their inputs! Humans have very accurate force sensors in their fingers, and no direct position sensors. Proprioception provides positio …

Image source Flight controls in airliners have long cable lengths in between the cockpit controls and the control surfaces. For instance in the picture above: the pilot operates the yoke, which defle …

The actuator extends linearly indeed, and is mounted on both sides with bushings that allow for rotation. As can be seen in above picture, from this site. So when the actuator extends: the end at th …

Yes they have a benefit, as demonstrated by the F-16 all-flying-tail (the stabilators) for almost half a century. Cropped image from the wiki With all of the horizontal tail deflecting there is a huge …

...if it is maintaining a certain g number, turn rate, angle of attack, or a mix of everything... A mix of everything. The computers adjust the active flight controls for: Providing artificial stab …

The A320 aileron actuators have servo valves of course, which when closed indeed allow no flow through them from pressure to return. They additionally have mode valves, which do provide a direct (damp …

I've worked with control loading systems quite a bit. What you describe is a reversible system, where the flight crew feels the aerodynamic forces acting on the primary control surfaces (elevator, ail …

Pic source Aircraft pitch motion is defined relative to the aircraft: when it rolls, the pitch axis rolls with it. And seen from the plane, pitch angle is still Angle of Attack plus Flight Path Angle …

In the multidimensional matrix of stability and control of aircraft, maintaining an earth reference position means unfortunately that the controller needs to consider multiple signals. Also, it needs …

Pic source Negative thrust, as in enabling the helicopter to fly upside down...but no, the aerobatic Red Bull helicopter does not perform sustained inverted flight, it does barrel rolls and loops whic …

My work on helicopter flight controls started more than 30 years ago, and at that time there were already helicopters is service with Automatic Flight Control Systems (AFCS) and Stability Augmentation …
