Do ATC say "Climb to XXXX on standard" or "Climb to standard XXXX" or something else?
Do ATC say "Climb to XXXX on standard" or "Climb to standard XXXX" or something else?
By "standard" I'm referring to altimeter pressure settings (set to standard pressure)...

Why does aircraft weight influence position (installation) error in pitot-static systems?
I am a private pilot from Argentina studying to become a commercial pilot. In one of the books I was given to study, published by the Chilean air force, the there's a claim (in Spanish, page 36) that ...

What is the effect of wind on altimeter reading?
I am wondering is there any effect from wind on the altimeter reading?
I think when the wind is blowing, the static pressure around the aircraft in flight will somehow change and this can impact the ...

Why are flights not also restricted during abnormally low barometric pressure conditions
FAR 91.144 talks about restricting flight operations during abnormally high barometric pressure conditions. Why would there not be an identical restriction during abnormally low barometric pressure ...

Should I add or subtract PA when calculating performance
I am planning a cross country and I wanted to know how would I calculate my PA for performance.
If the elevation of my airport is 16ft
and the altimeter setting for the day is 30.03
I subtract
30.03

Manual or other information regarding Kollsman Instruments B40331-10-276 altimeter
I just purchased a used altimeter from eBay because it'll look pretty on a shelf, and I may add a computer interface to it. However, I need help finding information on it.
This (from what I've been ...

is pressure altitude at different temperatures (different days) on the ground at the same airfield the same?
let's say we are at x-airfield which is at 0 MSL on the ground. We set the Kollsman window to 29.92 on a standard day, whatever the read is that would be the Pressure altitude, correct? (ideally zero ...

What should I follow, if two altimeters show different altitudes?
My school airplane has a Garmin G5 Electronic Flight Instrument and round gauge altimeter,
but they have almost 50ft differential. The G5 shows 50 feet higher on the same altimeter setting.
So in IFR, ...

Do altimeters still work in extreme angles of flight?
I've heard that the way the plane measures its altitude is to use a barometer to measure air pressure.
Does the pressure at the static ports drop as the aircraft's speed increases?
There is no ...

Air density factor when calculating Airspeed
I am making my own attitude indicator / AHRS, like a Garmin G5. I am using two pressure sensors to measure altitude & airspeed via static /pitot lines.
Now I know the formula for calculating ...

In the International Standard Atmosphere/ICAO, what is geometric and what is geopotential altitude?
Read first before you start considering it a duplicate, please, as the similar questions didn't answer my question either.
The usual standard atmospheres have two altitudes: the geopotential and the ...

What were the atmospheric models in the 19th century and early 20th century like, compared to the present-day ISA?
Atmospheric pressure has been used to determine the altitude a pilot (or a mountain climber as well) is at since the beginning of the age of ballooning.
I find the following Wikipedia excerpt about ...

Is the ISA still up to date?
The Standard Atmosphere dates back to 1962 when Earth was colder. The 1976 update didn't make changes within 50 km altitude (the tropo- and stratosphere). It assumes 15°C at sea level, decreases until ...
