Using take off distance chart, determine the take off distance, given: Temp = 75 deg F, Pressure altitude = 2000', Gross Takeoff Weight = 16,000lbs, 10kts headwind, 1% upslope, anti skid ON

• A. 5400 feet
• B. 6000 feet
• C. 6500 feet
• D. 7300 feet

Answer: (C)

Takeoff distance is driven by air density, weight, and runway conditions, with wind, slope, and braking capability altering the result on the chart. At 75 F and a pressure altitude of 2000 ft, the air is less dense than standard, so more runway is needed to reach liftoff speed. A gross weight of 16,000 lb also increases the distance since the airplane requires more energy to accelerate. A 10-knot headwind reduces the ground run, helping shorten the distance, while a 1% upslope adds a bit to the distance because you’re climbing a slope rather than starting on flat ground. Anti-skid ON improves braking effectiveness for an aborted takeoff, which the chart uses to reduce the distance slightly in that scenario. When these factors are combined on the takeoff distance chart, the result given is about 6,500 feet. The smaller distances would require more favorable conditions than those present, while the largest distance would come from more unfavorable inputs, so 6,500 feet is the best match for this set of conditions.
