Can my iPhone tell me my altitude?
Can my iPhone tell me my altitude?
If you only want to measure the height of a place you’re at, you can simply use the Compass app on your iPhone. It has a built-in elevation feature. To measure the altitude, use the free My Altitude app. The app uses both the device’s built-in barometer sensors and NOAA location data to give you accurate figures.
What is difference between altitude and elevation?
The elevation of an object is it’s height above sea level. Sometimes elevation and altitude are using interchangeable, however, altitude is the vertical distance between an object and the earth’s surface. We could for example use relief to describe the elevation, direction, and angle of slope of a mountain range.
How accurate is GPS altitude?
If a decent signal reception is available, a modern GPS receiver should be able to give elevation data accurate to a range of 10 to 20 meters (35 to 70 feet) post correction. And that’s exactly where the problem with GPS-based altimeter watches meant for the great outdoors lies.
Can my phone measure altitude?
Altimeter & Altitude Widget (Android) This app from DS Software (only on Android) uses location, barometer, and geospatial survey data to help you get accurate elevation and altitude readings, plus it comes with an array of maps and a feature that allows you to record and graph your altitude trends.

What altitude does altimeter read?
Reading The Altimeter Reading a standard 3-hand altimeter is easy. The long pointer measures altitude in intervals of 10,000 feet (2 = 20,000 feet). The short, wide pointer measures altitude in intervals of 1,000 feet (2 = 2,000 feet). The medium, thin pointer measures altitude in intervals of 100 feet (2 = 200 feet).
At what altitude shall the altimeter be set to 29.92 when climbing to cruising flight level?
24,000 feet MSL
What is the minimum safe altitude for a pilot to operate an aircraft anywhere?
500 feet

How do you calculate pressure altitude?
Find pressure altitude
- Subtract the current altimeter setting from the standard pressure of 29.92.
- Multiply by 1,000.
- If you have a negative number, subtract it from the field elevation. Add a positive number.
How much does air pressure change with altitude?
Since more than half of the atmosphere’s molecules are located below an altitude of 5.5 km, atmospheric pressure decreases roughly 50% (to around 500 mb) within the lowest 5.5 km. Above 5.5 km, the pressure continues to decrease but at an increasingly slower rate.
How much does air pressure decrease with altitude?
Near Earth’s surface the pressure decreases with height at a rate of about 3.5 millibars for every 30 metres (100 feet). However, over cold air the decrease in pressure can be much steeper because its density is greater than warmer air.
What happens to blood at high altitude?
Scientists have long known that the body adjusts to the oxygen-deprived conditions of high altitudes. The traditional explanation has been that low-oxygen conditions cause the body to build new red blood cells, making it easier to supply oxygen to muscles and vital organs.
