If your altimeter is set to 29.27" Hg and reads 2,000 feet, what is your pressure altitude?

To find the pressure altitude when the altimeter is set to a specific pressure setting, you can use the standard atmosphere rule, which states that for every inch of mercury (Hg) deviation from the standard pressure of 29.92" Hg, there is a corresponding change in altitude.

In this case, the altimeter is set to 29.27" Hg. First, calculate the difference from the standard pressure:

29.92" - 29.27" = 0.65"

Since every 1" of mercury corresponds to approximately 1,000 feet of altitude, you can convert this difference into feet:

0.65" Hg * 1,000 feet/inch = 650 feet.

Then, to find the pressure altitude, you need to adjust the indicated altitude (2,000 feet) by the 650-foot deviation:

2,000 feet + 650 feet = 2,650 feet.

Therefore, the correct pressure altitude is 2,650 feet, explaining why this answer is accurate and how it aligned with the pressure setting of the altimeter.
