Thank you so much for the excellent video! It's very clear for me to understand the working principle of barometric altimeter. Only one question: does it take real-time air temperature into account when converting the air pressure to altitude? If not, what's the constant temperature to use?

Hi i have a doubt if we look at the graph for barometeric pressure and altitude it is not linear, but the dial scale in an altimeter is linear how and where is the linearity compensated in a mechanical altimeter
@alielheshri6158

you absoluty right to make the reading linear the altemeter has correcting pins to increase or decrease the movement of the capsule accroding to altitude.

Hi, good job, I love this video. However I think the part about the expansion and contraction of the aneroid capsule is inaccurate. The pressure inside the capsule cannot stay the same, otherwise it wouldn't move an inch. The inner pressure of the capsule always adjusts to the static pressure around the aircraft and the capsule changes its volume as a reaction to this (Boyle's law). Or is there something that I'm not seeing?
@Slash1066
Жыл бұрын
Your comment really made me think, and I have to agree, if the capsule is able to increase its volume by expanding, the pressure inside must decrease. Assuming the capsule has 1 bar in it at sea level, then at lower pressure the capsule would expand until those pressures matched again, or until the expansion of the capsule reached its maximum or minimum movement values.

The pressure inside the aneroid capsule should be few Hpa 10-25 or it is calibrated to an internal pressure of 1013.25 Hpa?
@AviationTheory
2 жыл бұрын
Hi Daniel, you are right, normally the aneroid capsule is sealed with a pressure lower than the standard, but for the purpose of the explanation I decided to use 1013 hPa as a reference to make it easier to understand how it works.

In aviation, we are using feet for alt/height/elevation. Also in metric countries, as ICAO rules are set.

@ivansemanco6976 Russia and China are smart enough to use metres. Also GA in European countries often use metres also, just as many people here in Australia use metres. The international society of aviation actually recommends the use of metres globally, just that the US refuses to abide. Look it up. Soon aviation will go all metric.

@@chippyjohn1 its funny, years ago countries in Central Europe switch to feets… altimeters, all aviation maps and procedures are described in feets… we still have old metric atlimeters and VSI in the older planes. But officialy we are using feets, everywhere. So I lost hope for transition back to metric. But maybe you are right.

@@ivansemanco6976 The International Civil Aviation Organization (ICAO) is the governing body that makes official aviation recommendations. It might surprise a lot of pilots that for years, ICAO has recommended that the aviation world move completely to metric units (SI Units): Meters Kilometers Kilometers per hour Meters per second Liters Hectopascals Yep! No more knots. No more feet. The future of aviation is supposed to be 100% metric. Maybe. Someday. Don’t hold your breath.
