Downhill slope and Maximum mass for take-off
Hi,
This is a performance question:
If the take-off mass of an aeroplane is tyre speed limited, downhill slope would:
Answer: has no effect on the maximum mass for take off (according to FlyAround).
Well, I would have said that with a downhill slope you will accelerate to V1 faster, thus reaching V1 in a smaller distance which should allow you to take-off with a higher weight than with a zero slope runway.
Moreover in case of engine failure before V1, you will have more runway to stop the aircraft (... I understand that because of the downslope you will need a greater distance to stop the airplane but you do have that greater distance because V1 was reached sooner).
Who can explain the FlyAround given answer ?
Thanks,
