Meter1
- Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy. (adafruit.com)
Flight2
- Pressure altitude is primarily used in aircraft-performance calculations and in high-altitude flight (i.e., above the transition altitude). (wikipedia.org)
- b) after allowing for planned fuel consumption during the flight to the destination aerodrome or alternate aerodrome, exceeds the landing weight specified in the aircraft flight manual for the pressure-altitude and the ambient temperature at the destination aerodrome or alternate aerodrome. (gc.ca)

- However, a known density occurs for any one temperature and pressure altitude. (flight-study.com)
Aircraft5
- While traditionally a project geared more toward the model rocket crowd, a lot of people are flying quadcopters these days, and knowing the altitude your RC aircraft reached is a nice thing to know. (hackaday.com)
- Such helmet used primarily in high-altitude interceptors, such as the MiG-21, MiG-25 and MiG-31, but there were also popular test pilots working with other domestic aircraft modifications. (airtallweight.com)

Lower6
- Thin air exerts less pressure than air at a lower altitude. (microblife.in)
- The explosive products have extremely high velocities during the expansion process, which causes excessive compression of the air due to inertial effects, resulting in the pressure at the rear surface of the explosive products being lower than the initial pressure of the air, forming a negative pressure zone. (extrica.com)
- Because the atmospheric pressure is lower, the vapour pressure of the liquid needs to be lower to reach boiling point. (thecrucibleonscreen.com)
- Smaller number of particles pushing down on a given area means lower air pressure. (thecrucibleonscreen.com)
- Fewer molecules result in lower air pressure. (thecrucibleonscreen.com)

Increase7
- The result is an increase in the fluid's pressure. (easytocalculate.com)
- Why does pressure increase at high altitudes? (microblife.in)
- Due to the existence of the negative pressure zone, the high-pressure zone acts back on the negative pressure zone, causing the pressure in the negative pressure zone to gradually increase. (extrica.com)
