If you have a blocked static port, what is one recommended action?

• A. Increase altitude immediately
• B. Use an alternate static source
• C. Perform a controlled descent
• D. Land as soon as possible

Answer: (B)

Using an alternate static source is the recommended action when encountering a blocked static port. The static port is crucial for accurate readings of altitude, vertical speed, and airspeed, as it takes atmospheric pressure from outside the aircraft. If this port becomes blocked, the instruments relying on this pressure may provide incorrect information. By utilizing an alternate static source, which is typically located inside the aircraft and thus isn't affected by external atmospheric changes in the same way, pilots can obtain accurate readings necessary for safe flight operations. This alternate source allows the pilot to continue navigating and maintaining safe control of the aircraft despite the malfunction of the primary static port. Increasing altitude immediately could worsen the situation, especially if altitude readings are inaccurate due to the blockage. Similarly, performing a controlled descent or landing immediately might not be necessary and could lead to unnecessary urgency in a situation that can be managed by switching to an alternate static source. Hence, the use of an alternate static source is an effective way to address the problem while maintaining control of the flight.
