In a situation where cloud height data is available from the inactive runway and is representative when the active runway's cloud height equipment is inoperative, what should be used?

• A. Inactive runway data
• B. Active runway data
• C. No data
• D. Data from another airport

Answer: (A)

When cloud height data for the active runway isn’t available because the equipment is inoperative, use a substitute source that accurately represents the active runway conditions. If the inactive runway’s cloud height data is representative of the active area, it provides the necessary ceiling information for safe takeoff and landing decisions rather than leaving you without data. The active runway data can’t be used since the instrument isn’t functioning, and pulling data from another airport may not reflect local conditions. So, using the representative data from the inactive runway is the correct approach.
