Commercial aircraft are pressurized to the equivalent of 8,000 ft of altitude, or lower. That means air pressure in the cabin is lower, not higher. Many people in Colorado live at 8,000 ft. Your barometer should be fine.However, while you could bring a dial type barometer aboard the aircraft, a Mercury barometer could not be (hazard of the mercury in it.)

How do you change the calibration on the meter?
The word aneroid means literally no air, in reference to a box that is evacutated and has no air in it, which is the central part of an aneroid barometer. As air pressure increases, the evacuated box will be deformed by it. Calibrating a barometer,( for"swing") requires a hyperbaric chamber, a pressure source,(eg compressor), a set of accurate "Standards" gauges, a vacuum pump, and a pressure regulator. You take readings at various pressure points, then compare your readings obtained against your standards gauges. The internal mechanism is adjustable by varying the pivot point geometry, and also by resetting"set off point" via the vertical metal link strip, which has multiple holes. For most intents, setting an aneroid accurately by taking it to an NOAA Meteorolgy office is acceptable. Simply take it in, then adjust yours to the office's standard, either to read"true" or you can set it to read "corrected for altitude" ,(the number given on websites, or news forcasts, which IS NOT the TRUE barometric pressure)barometric pressure via adjustment screw in back. This does not tell you if it will remain accurate at points above or below the set area as the needle swings due to pressure changes.

How long will an airplane flying at an average speed of 500 miles per hour take to travel 2000 miles?
At 500 mph, it would take an airplane 4 hours to fly 2000 miles.
How to Predict the Weather Using a Barometer?
Of all weather instruments essential to forecasting, the barometer tops the list. Why? Because every weather change is preceded by a rise or fall in air pressure, and air pressure is just what the barometer measures. If you compare two barometer readings taken an hour or two apart, you will know immediately if the air pressure is rising, falling, or staying the same. And as a result you will be able, with a fair amount of accuracy, to predict tomorrow’s weather. RISING BAROMETER: When the air pressure measures higher than it did in your previous reading, the air is becoming denser, and the barometer is said to be rising. This tells you that clearer, drier, cooler weather is on the way. If the barometer is rising very rapidly from a low position, the weather will clear up very soon, and it will probably become quite windy. But if the barometer rises from a low position gradually and steadily, a long period of good weather is just around the corner. If the barometer is already high and suddenly starts to rise rapidly, expect a sudden drop to follow shortly, and with it, bad weather to come. FALLING BAROMETER: A falling barometer usually indicates rain, wind, and warmer weather. Take note of the speed at which the barometer falls. A very large and rapid drop in air pressure is a sure sign of an approaching storm. If the barometer falls suddenly, but not too far, expect wind and brief showers. If the barometer falls slowly and steadily to a moderately-low position, it may rain nearby, but not necessarily in your immediate area. UNCHANGING BAROMETRIC PRESSURE is a pretty good indication that whatever weather you’re currently enjoying is not about to change any time soon. IMPRESS YOUR FRIENDS AND NEIGHBORS! With a little experience in charting barometric pressure in your area, you will soon become skilled at noting any changes which are out of the ordinary. At this point, your weather-predicting abilities may begin to rival those of your local TV weatherman. And that would be something to brag about!
How do you calculate tak-off velocity of airplane?
peak height = (take off velocity^2)/(2*gravity)
Can a barometer can track the activity of storms at different altitudes?
No. A barometercan only take measurements from its own location, and barometric pressure alone is not enough to track storm activity. Weather balloons or planes with packages of instruments are needed to take readings from different altitudes.
Is it safe to take your cat onto an airplane?
No because some of the gas or air on the plane may hurt your cat. I suggest to take your feline friend on a pet airplane. A pet airplane is where pets are safe on planes. If you want to know more look it up.

yes. when you take the required training to dive you will learn everything you need to know to be safe as you dive. as always theres always risks to things. same as taking a risk when you drive a car or ride in a airplane.
Can you take medications on airplane?
Yes, I did and had no problem. Make sure they are in the bottles that came from the pharmacy or in the packages they came in. Just to be safe I brought along the little papers that come with them from the pharmacy.
