What is a stick shaker on an aircraft?

What is a stick shaker on an aircraft?

A stick shaker is a mechanical device that shakes the control column to warn of the onset of stall. A stick pusher may be installed in association with a stick shaker system in aircraft which are susceptible to the deep stall phenomenon.

Does Airbus have stick shaker?

There is no stick shaker available in an Airbus.

Is a stall warning horn required?

No, many aircraft don't have them, like the Cherokee since it uses a gear warning horn. The horn signifies that the gear isn't down and you don't want to confuse that with the stall warning, so they don't have one. ... So the stall buffet, as long as it is pronounced, is adequate indication of a stall to satisfy 23.

How does stall horn work?

The “lift detector” stall warning horn uses a tab that can be lifted during the preflight walk-around to sound the stall horn and requires an electrical system to operate. ... When the angle of attack increases such as during an approach to a stall, disrupted airflow raises the tab and that sounds the electronic buzzer.

What is stall buffet?

Buffet is a kind of vibration caused by aerodynamic excitation, usually associated with separated (or turbulent) airflow. As the aircraft approaches stall, the airflow over the wing becomes turbulent and if it flows across the horizontal stabilizer, buffeting may occur.

What will increase the stalling speed of an aircraft?

Stall speed increases as weight increases, since wings need to fly at a higher angle of attack to generate enough lift for a given airspeed. ... And wing contamination such as frost or ice can reduce the amount of lift produced by the wing, also raising the stall speed.

Does landing gear affect stall speed?

Flaps, landing gear, and other configuration devices can affect an airplane's stall speed. Extension of flaps and/or landing gear in flight will usually increase drag. Flap extension will generally increase the lifting ability of the wings, thus reducing the airplane's stall speed.

Why does stall speed increase with altitude?

Because of the progressive reduction in air density, as the aircraft's altitude increases its true airspeed is progressively greater than its indicated airspeed. For example, the indicated airspeed at which an aircraft stalls can be considered constant, but the true airspeed at which it stalls increases with altitude.

Why is it called coffin corner?

The name comes from the "coffin corner" found in Victorian houses (the slang and often refuted term for a decorative niche, or very small 'corner', cut into the wall of a staircase landing), because the target area is very small. ...

Can a plane stall on takeoff?

The slower an aircraft flies, the higher the angle of attack must be in order for the aircraft to have enough lift. If it does not reach the necessary stallspeed, the stall occurs. Shortly after take-off, an aircraft needs considerable thrust in order to simultaneously increase its speed and gain altitude.
