Temperature - low temperature gains altitude quicker
Pressure - High pressure gains altitude quicker
Density - Low density gains altitude quicker
Radar altimeter gets altitude information by bouncing a radio wave off the surface of the Earth and determines the aircrafts altitude by measuring the length of time it takes for the signal to return. Barometric altimeters get altitude information by measuring the barometric air pressure outside the aircraft. Barometric pressure decreases as altitude increases. Radar altimeters will give altitude above ground level while barometric altimeters give altitude above sea level.
An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose. See related link The altimeter measures the height above the ground and has a pointer which is adjustable depending in which air field you are taking off on. it measures the pressure of the air as you get higher off the ground the pressure reduces therefore it is able to determine your height above ground.
Electronic equipment can operate just fine in high altitude. You simply need to account for environmental issues, such as heat dissipation. Take, for instance, electronics in a satellite - that is the ultimate high altitude.
Magnets.
The Gulfstream GV can climb directly to an altitude of 37,000 feet in eighteen minutes, then continue to 43,000 feet for a high speed cruise of 488 knots, or climb to 45,000 feet for a long-range cruise of 459 knots. The highest altitude that it is certified to fly at is 51,000 feet.
Atmospheric pressure will decrease as altitude increases.
The rockets which fly in the stratosphere and the high altitude aircrafts
No. Atmospheric pressure decreases as altitude increases.
altitude
The opposite is true. Atmospheric pressure decreases with altitude.
as altitude rises less there is less atmospheric pressure
When standard atmospheric conditions exist.
A barometer is used to measure atmospheric pressure. It can also measure altitude!
Determining altitude visually is impossible. You could easily go wrong. That's why there are altimeters present in all aircrafts.
A barometer is used to measure atmospheric pressure. It can also measure altitude!
the astronomical parameters are 1-elongation 2-altitude at the time of sunset 3-width of lunar disc
it is a deviation from the normal change of atmospheric properties with altitude
