Final answer:
Errors with the pitot and static systems can affect the reading on an airplane's airspeed indicator (ASI). If there is an error in the pitot system, it can cause the ASI to indicate lower than the actual airspeed. If there is an error in the static system, it can cause the ASI to indicate higher than the actual airspeed.
Step-by-step explanation:
When there are errors with the pitot and static systems in an airplane's airspeed indicator (ASI), it can affect the reading on the ASI. If there is an error in the pitot system, such as a blockage or icing, it can cause the ASI to indicate lower than the actual airspeed. On the other hand, if there is an error in the static system, such as a blockage or leaks, it can cause the ASI to indicate higher than the actual airspeed.
For example, if the pitot tube is blocked, it won't measure the dynamic pressure properly, leading to a lower reading on the ASI. Similarly, if there is a leak in the static system, it will cause the ASI to measure more static pressure than there actually is, resulting in a higher reading.
Therefore, the correct answer is B) Indicates lower than actual.
