What is the maximum airport pressure altitude?

• A. 8,000 Feet
• B. 7,000 Feet
• C. 9,000 Feet
• D. 10,000 Feet

Answer: (A)

Pressure altitude limits influence how far you can safely operate based on performance data. The maximum airport pressure altitude is the highest altitude at which the published performance data for normal operations remain valid. As pressure altitude increases, the air gets thinner, reducing engine thrust, wing lift, and overall climb and takeoff performance. That limit is 8,000 feet in this context, so 8,000 feet is the correct maximum. Values below that, like 7,000 feet, are within the limit; values above it, such as 9,000 or 10,000 feet, exceed the limit and would require different procedures or data.
