The term has two different meanings in separate areas of electrical engineering. In antenna theory, a ground plane is a conducting surface large in comparison to the wavelength, such as the Earth, which is connected to the transmitter 's ground wire and serves as a reflecting surface for radio waves.
What does it mean when a plane is grounded?
Grounding an aircraft or aircraft type, (or even an individual pilot or airline), means that they are banned from flying in the country they have been grounded in. This is the only part that's wrong: grounding a plane is indefinite unless a timeframe is specified.
What is grounding and why is it important?
If a device malfunctions and begins drawing a dangerous amount of current, grounding allows the circuit to safely dissipate the excess charge. Not only does this protect other connected devices from failure; it also protects people around the device from shock or electrocution.
What is the meaning of the word 'ground'?
The use of the word "ground" as a verb here is a bit unusual for a non-native, but it literally means that it has to be on the ground (meaning floor/Earth) Grounding an aircraft or aircraft type, (or even an individual pilot or airline), means that they are banned from flying in the country they have been grounded in.

Why is grounding important in airplanes?
In Aircraft. Grounding is essential to creating a safe environment when using high-powered electrical devices. If a device malfunctions and begins drawing a dangerous amount of current, grounding allows the circuit to safely dissipate the excess charge.
What is grounding in electrical?
Grounding actually refers to the use of a low-impedance path through which high, potentially dangerous levels of current from a circuit can flow. If current levels exceed the limit for which circuit and its devices are rated, the excess electricity will travel through the path of least resistance.
What is the purpose of static dischargers in airplanes?
Most airplanes are also designed with static dischargers or “static wicks” that release this excess electricity into the atmosphere. To better understand grounding in airplanes, you should examine the way in which they are able to safely absorb lightning strikes.

Why are passengers bumped on flights?
Another factor is that passengers bumped due to cancellations traditionally have been accommodated on other flights operated by the same airline or even rival carriers. But record-high passenger loads have made this quite difficult in recent years; according to the U.S. Department of Transportation, the latest data for 2012 indicate cabins on U.S. airlines are 83% full, leaving little room for spillover from canceled flights. And codesharing marketing deals mean interline agreements among airlines that are not aligned have tightened, making it harder to have your ticket honored elsewhere.

What is grounding electrical?
Grounding on the other hand is to give stray electrical current a place to go, other than through you. To some extent, the two work together with each other, sort of as backups for each other.
Where should the fuel truck be grounded?
In simple terms, the aircraft should be bonded to the fuel truck, and the fuel truck should be grounded to the ground post on the ramp.
Why do we bond?
A: A simple explanation of bonding is that it is done to prevent you from being shocked/electrocuted when your left hand touches one metal component, and your right hand touches another metal component. By running a wire (bonding wire) from one metal component to another (fuel truck to aircraft), stray electricity (from a short for example) will equalize through the wire and one metal component (truck) will NOT have a greater voltage in it than another metal component (plane), hence no spark.

How does a CB antenna work?
A typical mobile CB antenna does not transmit horizontally, it radiates in a downward pattern. A metal surface (the larger and flatter, the better) is required underneath the CB antenna to launch the signal out into the atmosphere. Without an adequate ground plane surface, the signal will not travel out into the atmosphere which results in limited ...
What is a ground enhancer?
Ground Enhancers. There are several devices available that can enhance your ground plane. This is accomplished by normally adding a 3 point radial to the bottom of the antenna.

Can you ground a plate at infinity?
EDIT: Note that there is a bit of a subtlety in how you ground the plate. If, as would be most natural, it means connecting a wire to a distant grounding point, you may effectively be grounding at (near) infinity and only change the potential by adding another metal bit.
Can you ground a conducting plate at zero?
It depends where and how you ground your conducting plate. If it is grounded at infinity, where the potential of your charge is zero, it should not change anything over an already (net) uncharged plate. However, if you tie any bit of the plate that would otherwise be at a nonzero potential to zero, you will cause the plate to become charged as a consequence, which will affect the overall potential.
