In the takeoff distance scenario with 16,000 lbs, what is the upslope percentage used?

• A. 0%
• B. 0.5%
• C. 1%
• D. 2%

Answer: (C)

When calculating takeoff distance, runway slope is accounted for as an upslope percentage. An uphill slope makes the aircraft need more distance to accelerate and lift off, so the required distance is increased by that percentage.

For a weight of 16,000 pounds, standard performance data specify using a 1% upslope adjustment. So the upslope factor applied is 1%, reflecting the moderate incline associated with that weight category.

The other options correspond to flatter or steeper slopes not aligned with the 16,000 lb case: 0% is flat, 0.5% is a smaller slope, and 2% is a steeper slope than what this weight uses in the chart.
