Is this indicated altitude?

Question

Prior to takeoff, each pilot sets the aircraft's altimeter with the correct altimeter setting of the airport from which the pilot will depart. This setting is called ?

Answer 1

Sure is. Indicated is what you get when you put in the local altimeter setting.

You get pressure altitude if you set the standard of 29.92

It's that easy!

Answer 2

It's called "pressure altitude".

Pressure altitude is altitude corrected for non-standard barometric pressure. So when the ATIS or tower controller says "altimeter two-niner- niner- eight", you're adjusting the altimeter to show the effect of the barometric pressure of 29.98 Hg. The indicated altitude part of it is that the altimeter now shows a slightly higher elevation.

BTW, if you took it one step further and adjusted for higher than standard temperature (above 15 deg C), you'd have "density altitude". Many a crash in the hot summer months is due to a failure to account for density altitude; it kills your climb rate!

Answer 3

Yes, the altitude shown in your example is indeed "indicated altitude".

That has nothing to do with pressure altitude unless the altimeter setting is standard pressure (29.92).

If you are asking about the altimeter setting itself (the number you dial into the Kollsman window), in the US, that's usually just referred to as the altimeter setting.  Internationally, it's known as QNH.

Answer 4

Local altimeter setting.  QNH.

Answer 5

The setting put into the Altimeter is called Pressure Altitude in "Inches of Mercury" Standard pressure is 29.92 but due to the constant Nature of change in our atmosphere that number is rarely at that value.

in a Metar

A3022 represents Altimeter setting (Inches mercury, If you're anywhere besides the US pretty much they use Millibars Standard pressure 1013.2 Mb) so in this case you would set the Altimeter to 30.22..............When it comes to airplane performance Density Altitude comes into play, Density altitude is For Performance related information......it is Pressure Altitude Corrected for Standard Temperature wich is 15*C/59*F, Say you're at 5 thousand feet and we use the METAR above Density Altitude is 5100 feet, wich means even though you are 5000 feet above sea level your airplane will perform as if it where 5100 feet above sea level.....that's a very subtle difference but Density altitude can vary up to a few thousand feet or worse depending what the weather's like ;)
