Clarrie,
Thanks for that. Although the departure gradients are substantially different, the figure do illustrate very nicely the advantage of the 21K engines over the 18.5K engines at ASP.
Andyn,
Welcome...
Unfortunately for those folk who are not as familiar with the 717 performance, just promising an extra 5 tonnes doesn't mean a lot. Given that the uncontrolled variable is the OAT, the increase in critical temperature for MTOW tells most of us quite a lot about the advantages of dialling up increased thrust.
BPA,
You are quite right to highlight the typical N departure, but I think for this context the full length is relevant since that is your last option before restricting the load.
Stay Alive,
