How do you determine takeoff and landing performance from weight and balance data?

• A. Use performance charts with weight, balance, altitude, air temperature, and pressure; compute V speeds and required runway
• B. Use weight alone
• C. Use a random estimate
• D. Use only altitude

Answer: (A)

The idea being tested is that takeoff and landing performance comes from translating the current weight and balance into performance figures using charts that account for how the airplane behaves in its environment. You don’t rely on weight alone; you use the performance charts in the POH/AFM that take weight, center of gravity, density altitude (which comes from altitude, air temperature, and pressure), and other factors like runway condition to determine the required runway and the speeds you’ll use. By locating your weight and CG on the chart and applying the density altitude, you read off the expected takeoff and landing distances and the appropriate V speeds. Heavier weight generally requires longer distances and adjusts V speeds, and the CG position affects stability and performance reflected in the charts. The other options fall short because weight alone, a random estimate, or altitude alone don’t provide the full picture needed to accurately determine takeoff and landing performance.
