Which action is part of preparing for a runway friction test?

• A. Ensure controlled conditions for testing
• B. Conduct the test in unpredictable weather
• C. Ignore calibration of the device
• D. Test without any equipment

Answer: (A)

Preparing for a runway friction test means creating a stable, repeatable testing environment so the friction reading reflects the runway surface and the instrument, not changing conditions. Keeping conditions controlled—dryness, moisture level, surface temperature, and weather stability—helps produce a friction value that can be trusted and compared across tests. If testing happens in unpredictable weather, the data will vary with rain, temperature swings, or moisture, making the result unreliable. Skipping calibration of the device or testing without equipment would also undermine accuracy, so those are not part of proper preparation.
