Altimeter setting region?
The altimeter setting region refers to the area of an airport where a specific altimeter setting is in use for all aircraft operating within that region. This is crucial for ensuring accurate altitude readings and maintaining safe vertical separation between aircraft. Pilots must set their altimeters to the correct setting in order to accurately determine their altitude above mean sea level.
What is the intrument that tells pilots how far up in the air they are?
Its the altimeter
How does air traffic control know what barometric pressure to give pilots enroute?
Typically, enroute aircraft cruise at or above FL180, in which the barometric pressure (or altimeter) setting is standardly 2992. However, if aircraft are below FL180, ATC must issue the nearest accurately reported altimeter setting from an airport every few miles.
When the barometric pressure is greater than 31.00 what altimeter setting would you issue?
When the barometric pressure is greater than 31.00 inches Hg., issue the altimeter setting and: 1. En Route/Arrivals. Advise pilots to remain set on altimeter 31.00 until reaching final approach segment. 2. Departures. Advise pilots to set altimeter 31.00 prior to reaching any mandatory/crossing altitude or 1,500 feet AGL, whichever is lower.

What is a 1013mb?
it's the standard pressure at which all pilots set their altimeter, when communicating Fight Levels.
What instrument do airplane pilots use to detremine altitude?
S(he) uses an altimeter which a kind of airborne barometer.
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.
On what principle does an altimeter of a Cessna 172 aircraft works?
The altimeter in a Cessna 172 aircraft works on the principle of barometric pressure. As the aircraft gains or loses altitude, the atmospheric pressure changes accordingly. The altimeter measures this pressure difference to provide an indication of the aircraft's altitude above sea level.
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 tells you how high a plane is flying?
An altimeter (altitude meter) tells the pilots how high the aircraft is flying. There are 2 types of altimeters commonly used in aircraft: pressure altimeters and radar altimeters.
How do pilots find there way around in the sky?
With their altimeter. An instrument on the craft's dashboard, called an altimeter, reads the altitude of the craft. In addition, every airfield has a designated altitude above Mean Sea Level assigned, to help calibrate and interpret actual altitudes above ground level.
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.
