First, determine the difference from standard pressure 29.92.
30.12
-29.92
---------
.20
If you drop the decimal point and add a zero you get the number of feet of difference, so .20 = 200 feet. Since 30.12 is a higher number than 29.92, you subtract it from the actual altitude. If the indicated altitude is 10000 feet, your pressure altitude is 9800 feet. If your altimeter setting is lower than 29.92 you add the difference.
It can also be expressed as PA = IA + ((29.92 - AS) * 1000) where IA is indicated altitude and AS = altimeter setting.

What is the hardest part in setting up an experiment?
The hardest part in setting up an experiment usually depends on the nature of the experiment. However, the most critical part of setting up an experiment is forming a testable hypothesis.
What is the pressure altitude at 1000 ft if the altimeter is 30.00?
Pressure altitude is the altitude above the standard datum plane where the altimeter is set to 29.92 inHg. If the altimeter setting is 30.00 inHg at 1000 ft, the pressure altitude would be lower than 1000 ft since the altimeter setting is higher than standard.
When Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates?
true altitude at field elevation.
Do the aneroid wafers in an altimeter move when you adjust the altimeter setting?
No, that wafers do not move independent of the hole part. When pressure is adjusted, the whole base of the altimeter, including wafers, turn. Thus it changes the setting of the altitude. While the whole base is turning, the barometric pressure dial turns accordingly to show the correct pressure reading you are adjusting it to.
How do you convert altimeter setting 30.12 pressure?
First, determine the difference from standard pressure 29.92. 30.12 -29.92 --------- .20 If you drop the decimal point and add a zero you get the number of feet of difference, so .20 = 200 feet. Since 30.12 is a higher number than 29.92, you subtract it from the actual altitude. If the indicated altitude is 10000 feet, your pressure altitude is 9800 feet. If your altimeter setting is lower than 29.92 you add the difference. It can also be expressed as PA = IA + ((29.92 - AS) * 1000) where IA is indicated altitude and AS = altimeter setting.
What If a flight is made from an area of low pressure into an area of high pressure without the altimeter setting being adjusted the altimeter will indicate?

On what principle does an altimeter of a Cessna 172 aircraft works?
The altimeter works by measuring minute changes in barometric pressure. Barometric pressure decreases as altitude increases, and altimeters are able to detect this change and use it to determine altitude. Barometric pressure is also effected by weather conditions, and so pilots must frequently adjusting the altimeter setting in order to compensate. Some new cessna 172's are being equipped with Garmin GPS cockpits which also get altitude information from GPS receivers, but these aircraft are also equipped with a standard altimeter in the interest of redundancy.
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.
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.
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 the transition altitude in the US?
The transition altitude in the United States is typically 18,000 feet above mean sea level. This is the altitude at which aircraft transition from using the altimeter setting in inches of mercury to a standard setting of 29.92 inches of mercury.
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.
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.
