Using take off distance chart, determine the maximum takeoff weight, given: 7000' Takeoff distance available, Temp = 75 deg F, Pressure altitude = 2000', 10kts headwind, 1% upslope, anti skid ON

• A. 15200 lbs
• B. 15600 lbs
• C. 16200 lbs
• D. 17000 lbs

Answer: (C)

Takeoff distance charts connect the weight of the aircraft to the distance needed to reach liftoff under the current field conditions. To find the maximum takeoff weight for a fixed runway length, you locate the weight whose required takeoff distance matches the available distance, given the temperature, altitude, wind, and slope.

Here, the 7,000 feet of runway must accommodate the takeoff run. The 75°F temperature and 2,000 feet pressure altitude reduce air density, which tends to increase the distance needed for a given weight. The 10-knot headwind helps shorten the required distance, while the 1% upslope adds to it. Anti-skid being ON doesn’t change the takeoff distance on the chart. When these factors are applied, the weight that aligns with about 7,000 feet of required distance is roughly 16,200 pounds. Lighter weights would need less than 7,000 feet, while heavier weights would exceed the available runway. That’s why 16,200 pounds is the maximum.
