Question 1

In which way may an altimeter subscale which is set to an incorrect QNH lead to an incorrect altimeter reading?

Accepted Answer

If the subscale is set to a higher than actual pressure, the indication is too high. This may lead to much closer proximity to the ground than intended

Answer

If the subscale is set to a higher than actual pressure, the indication is too low. This may lead to much greater heights above the ground than intended

Answer

If the subscale is set to a lower than actual pressure, the indication is too high. This may lead to much closer proximity to the ground than intended

Answer

If the subscale is set to a lower than actual pressure, the indication is too low. This may lead to much closer proximity to the ground than intended
