Why should barometric pressure be corrected for the vapor pressure of water?
In order to answer your question, first I will briefly explain how an altimeter works. An altimeter senses current atmospheric pressure, and converts it into an altitude reading. The lower the pressure, the higher altitude it will show. In aviation, the pilot needs to select the correct altimeter setting before takeoff and during flight in order to get a correct reading. This is required because the pressure at sea level changes based on weather conditions. For example, if I parked my aircraft at an airport, then came back the next morning, my altimeter would give me a different reading than before because the weather conditions changed slightly overnight. I would then have to change the altimeter to the current local altimeter setting. The local altimeter setting is defined as the atmospheric pressure at Mean Sea Level (MSL) in inches of mercury. Once the altimeter has the pressure at sea level, it can give an accurate reading of the current altitude. Air Traffic Control keeps pilots updated on the local altimeter settings as they fly. The other way to calibrate an altimeter, this only works on the ground, is to turn the pressure selector until the altimeter show the elevation of the airport you are currently at. At this point, the pressure shown is the local altimeter setting.
Why should the local altimeter setting be used by all pilots in a particular area primarily for?
To provide a better vertical separation of all aircraft.
HOW TO Prepare an altimeter?
To prepare an altimeter for use, ensure it is calibrated to the correct setting for the current location, typically using the local air pressure. Check that the altimeter is properly attached and functioning correctly. Familiarize yourself with the altimeter's display and features before relying on it for accurate altitude readings.

What is a sentence using the word altimeter?
The pilot checked the altimeter to be sure the plane had reached the optimum altitude before the skydivers were allowed to jump. Most altimeters have to be set to local air pressure to correctly determine the plane's height above the ground.

Why is the air more dense at sea level than at a mountain top?
In simple terms - gravity ! The closer you are to the Earth's core - the higher the gravity. At mountain summits - the gravity is less - therefore the air molecules are able to move further apart.

Why you have flight level in aviation?
Flight levels exist in aviation to make high altitude flying easier on pilots and controllers. First, some background. Since the altimeter uses atmospheric pressure to measure altitude, weather conditions can effect the reading on an altimeter. For example, if a high pressure system comes in, the altimeter in the aircraft would read lower than you actually are. For that reason, whenever a pilot gets in an airplane, he has to set the altimeter to the correct atmospheric pressure. As the pilot flies, Air Traffic Control will give him updated altimeter settings for the area he is in. However, once you get high enough, your actual altitude doesn't really matter; you only need to know altitude so ATC can keep you separated from other aircraft. For that reason, upon passing 18000 feet, all pilots reset their altimeter to the standard setting of 29.92 inches Hg. This relieves controllers and pilots from constantly recalibrating their altimeters, while still keeping aircraft separated. The distinction between an altitude measured by local altimeter settings versus the standard setting is "Flight Level". Any altitude below 18000 ft will be given by ATC as "feet" (exe. "Climb and maintain one-one thousand feet"); where any altitude above 18000 ft will be given as a flight level (exe. "Climb and maintain flight level two-six-zero). Flight level numbers are given in feet times 100, so FL 260 would be the equivalent of 26000 ft.

What causes variations in altimeter settings between weather reporting stations?
Variations in altimeter settings between weather reporting stations can be caused by differences in elevation, atmospheric pressure, and local weather conditions. Changes in temperature, humidity, and air density can all impact altimeter settings. Additionally, the accuracy of the instruments and calibration process at each station can also contribute to variations.
