Final answer:
The pressure altitude can be determined by subtracting the airport elevation from the altimeter setting.
Step-by-step explanation:
The pressure altitude at an airport can be determined using the altimeter setting and the airport's elevation. Pressure altitude is the altitude above the standard atmospheric pressure at sea level. To determine the pressure altitude, subtract the airport's elevation from the altimeter setting. In this case, the airport is at 3,563 feet MSL and the altimeter setting is 29.96, so the pressure altitude would be 29.96 - 3,563 = 3,533.04 feet.
