Hi
I had a question in one of your on-line PPL Exam Prep units (see below)
I followed the chart and got 1030kg as my answer. The answer in the review is 1000kg.
I'm afraid I cannot see the error. I used 20kt headwind (Rwy 08). I'm now unsure if I understand how to use these charts.
Can you please confirm the right answer?
Thanks.

Surface = long dry grass
Slope = level
Pressure Height = 5000 ft
Wind = 080/20 kt
Temperature = +25 Deg C

The heaviest take-off weight permitted under the conditions given is closest to:

The line going up from the 25°C temperature line to the distance available box, crosses the climb-weight limit line on the way up. If you move horizontally to the right from that point, you will hit the weight scale at 1000 kg. That means that even though the take-off distance available would allow you to take-off at over 1000kg, you would not be able to climb at the required gradient at that weight. You would have to limit your take-off weight to 1000kg to meet the climb gradient required after take-off
