Salty. I kid. Loved talking to you guys when I flew that baby dog into and out of EWR. You guys were awesome. Now the 757, there’s a real airplane.

That might be true if the benefit was equal across all population densities, but it is clearly not.

@SlumTodd_Millionaire I feel like a broken record here.
The 717 has design characteristics superior to even the 757. It’s thrust-to-MTOW ratio and MTOW-to-wing area ratio (“wingloading”) are best is best in class, which give it rocket-like performance capability if the operator so chooses. It’s built that way to handle of small/challenging airports, but truth is, it’s way overbuilt for most of its missions. You could release some performance margin and it would still be quite capable, and would save a lot on fuel burn.
If you’ve got beef with its climb performance, take it up with the operator...not the airplane itself!

We are there to protect the fare paying flying public , pilots are just a middle man , if people didnt fly there would be no use for either

So, you're there for the pilots, who are there for the passengers. Got it.

I mean we're only here cause ya'll kept runnin into each other back in the day. But what any of that has to do with every single controller despising the climb rate of the 717 beats me.

You're gonna confuse the caveman controller. Go easy on him.

Isn't that still a shortcoming on the 717's part though? Apparently most other types can climb fast economically, but it's prohibitively expensive for the 717 to climb at the same rate as comparable aircraft.

It's not prohibitive at all. The manufacturer simply created reduced thrust climb profiles for the 717 that save a lot more money than the climb profiles on other planes. For example, someone mentioned earlier reduced climb profiles on the 737 of only 3% and 6% thrust reductions. That's minuscule compared to the 717's reductions. That means the 717 saves a lot more money. If you put it up against the 737 with a full thrust takeoff and climb, though, you're really not going to see a difference. In fact, it will probably climb a lot faster than some models, like a -900.

That's really not hard. A one winged sparrow climbs better than a 900, especially the ERs.
