Hydraulics in light aircraft are primarily used to transmit braking forces from the cockpit to the brake disk or drum.

• True

• False

According to the passage, what does an aircraft hydraulic system allow to be applied, multiplied, and transmitted from one location to another?

• forces

• electricity

• fuel

• signals

Hydraulics are a critical system on almost all modern aircraft.

• True

• False

Which of the following is NOT mentioned as a use of hydraulics in aircraft?

• Braking

• Actuating landing gear

• Providing in-flight entertainment

• Controlling flaps and control surfaces

According to the principles of hydraulic operation, what law does a hydraulic system operate on?

• Pascal's Law

• Newton's Law

• Ohm's Law

• Boyle's Law

Pascal’s Law states that the change in pressure at any point in a contained incompressible fluid must be transmitted throughout the fluid such that the ________ occurs equally everywhere.

• pressure change

• temperature change

• volume change

• density change

In a hydraulic system, if the pressure inside a hydraulic line is changed, the increased pressure will be transmitted equally to all points in that system.

• True

• False

Which of the following best describes Pascal's Law?

• The pressure change occurs only at the point of force application.

• The pressure change occurs equally everywhere in a contained incompressible fluid.

• The pressure change is not transmitted in a hydraulic system.

• The pressure change is only transmitted to the largest area.
