Fergus,
On many aircraft it is advantageous to take of with flap up.
For 'Performance A' aircraft when calculating the 'Net Take Off Flight
Path', some a/c can make the second segment climb gradient with flap up but
not with take-off flap. This is the case with the Falcon 20 under hot and
high situations.
regards,
Mike Parkin
