Standard pressure altitude is a useful tool for pilots. By comparing the conditions at an airport to the standard, they can quickly estimate how their aircraft will perform on a given day. Which of these statement is true about standard and actual pressure altitudes?
A) If the pressure that day is above the standard, aircraft performance will be lower.
B) Standard pressure altitude doesn't affect aircraft performance.
C) If the pressure that day is below the standard, aircraft performance will be higher.
D) If the pressure that day is above the standard, aircraft performance will be higher.
E) None of these
