What is the standard altimeter value in QNH and inches of mercury?

Answer 1

1013 hPa / 29.92 inches Hg

Question 2

How many feet equals 1 hPa

Answer 2

27ft or rounded off to 30 ft

Question 3

When QNH is greater than 1013, pressure altitude is higher or lower?

Answer 3

Lower

Question 4

Formula to compute for difference in height based on QNH

Answer 4

1. (1013 - actual QNH) = A
2. A x 30ft = B
3. B + or - pressure height = final height

(if QNH is greater than 1013, subtract, else if lower, add to pressure height)
