What was the takeoff distance over a 50-foot obstacle in the scenario?

• A. 1,980 feet
• B. 1,800 feet
• C. 2,100 feet
• D. 2,400 feet

Answer: (A)

Takeoff distance over a 50-foot obstacle is the horizontal distance from the start of takeoff to the point where you have cleared the obstacle, with the required clearance above it. To determine this, you use the aircraft’s takeoff performance data for the specific conditions (weight, density altitude, wind, runway slope, etc.). The distance you read on the performance chart is the sum of the ground roll (distance to liftoff) and the distance traveled while climbing to reach at least the 50-foot obstacle's height at the obstacle location, maintaining the required climb gradient.

In the scenario, the performance data under the given conditions specify the distance needed to clear a 50-foot obstacle as 1,980 feet. That is why this option is correct. The other distances would result from different conditions or data not present in this scenario.
