In performance planning, a safety factor of 1.43 is applied specifically to which aspect?

• A. Landing distance required (LDR) for standard operations
• B. Contaminated runway takeoff performance
• C. LDR, when calculating the landing distance
• D. Dry grass runway takeoff performance

Answer: (C)

In performance planning, a safety margin is added to the landing distance to cover uncertainties in how the aircraft will actually perform on rollout. The factor 1.43 is used specifically with the landing distance required (LDR) when you're calculating the distance you need to land safely. By multiplying the LDR by 1.43, you create a conservative landing distance that accounts for variations in braking effectiveness, wind effects, pilot technique, runway conditions, and other small surprises during landing. This margin is not applied to takeoff distances or to special cases like contaminated runways or dry grass takeoffs, where separate performance considerations apply. So, the best choice reflects applying the safety factor to the landing distance calculation itself.
