Question:
Also, are they grounded when they land before passengers get out?
Answers:
I need to know the total number of aircrafts registered in the world (by continent).?
All of the above have pieces of the correct answer. Yes the airframe is ground. There are static wicks on the trailing edges of the wings and fuselage at various points to dissipate the static build-up when the plane is flying. On the ground there are various methods of grounding the airframe, such as thru the ground power unit or via grounding lines attached to lugs in the earth used especially when fueling or defueling the aircraft, or when performing maintenance on the fuel system.Between the static wicks and the ground power unit, the airframe is grounded enough that passengers don't have to worry about getting shocked when deplaning.
The electrical ground is through the metal airframe of the fusilage, this is the same as with a car.
When the aircraft is docked at the gate, an electical connection is made through a socket on the side of the fusilage to the airport electical systems which includes a live power connection and a ground.
'Ground' is generally the airframe. The negative on the battery and generators are connected to the airframe and most electrical devices are terminated on the airframe. The exception is avionics which can pick up interference from an airframe ground.
does anyone know of a good flight school in Houston?
All components of an aircraft are bonded together (like engine to airframe and flight controls to airframe) and there are static-discharge wicks on the aircraft extremities to maintain a neutral charge.
What is the best aircraft to start a long haul charter with? From Atlanta to Nigeria?
Aircraft are generally grounded when they are fuelled and being worked on. Also some aircraft have ground straps on the landing gear to help ground it. Static charges build up when fuelling and there have been some pretty big explosions as a result of not grounding the aircraft.
what is/was the biggest aircraft ever made besides the spruce goose Howard Hugh's had built?
Interesting question. I believe the metal mass of the body of the plane then serves as a ground system. I don't believe, by these website's explanation, that there would be any charge by the time the plane touched down. Since the plane is effectively "ground", when the plane touches down, it is ground to ground so no charge. Check out these websites for a better explanation:How does the fuel efficiency of a jet engine compare to that of an internal combustion engine?

can i land on mt. everest in a helicopter??
Many airplanes have grounding "tails" on the trailing edge of thewings. This helps but is not 100% effective. Any charge built up
during a flight is minimal and is discharged before you reach the
door. Avionics are much more sensitive to electrical charges than are people.. Airplanes are made primarily of aluminum which is a poor conductor so running a ground wire is a rule, not
an exception. Electrical operations are the same as in a car
except for the ground wires that usually must be included.
Where can I find a video of a plane crash landing over sea?? (in the cockpit if available?)?
The ground if the dirt that people track into de planereserve seats during check-in or upon payment of tickets?
The airframe is the ground. However, to understand this, you need to stop thinking aircraft and start thinking general electronics.What are some things a new airline pilot should look for?
Ground is not a measurable thing, it is a reference point. So 12 volts is basically 12 units of measure above your reference.
