No... The aircraft will only give you an indication if the flaps are not set in a "Takeoff" setting.

Even as the FO, I'm going to take a quick look at the WDR to verify the line the CA selected, especially if he's manually entering stuff on the perf page. In your example, the big question in my mind is why didn't he take the second line on the uplink?

Then the flaps 3 performance you think you have will all be invalid. The airplane will do what you told it to do (flaps 1) but you may not have sufficient performance for rwy wt or second segment climb since the wt data was based on flaps 3.

Totally hypothetical scenario but as a former standards instructor at a previous company I was looking for gotchas. Company procedure - at least for now - is to manually enter it. Which to me, provides an opportunity for error. Then we check the aircraft setting from the entry, not the data we printed. Middle of the night transcon after a day sleep and a real fatigue related error could result.

At AA I read off the performance paperwork (TPS here) what is planned, and confirm selected flap setting by checking the flap handle and the screen.

When I flew the 88 and 75 we had wind additives as high as or higher than any gs mini I've used. Except the 717 where they didn't want us adding an additive... and we had the landings to show why you need an additive.

On the flip side, if you're in KBUR and you don't get flaps 3, I would do some investigating. Hopefully S.A. kicks in and you catch it....which can be difficult after a day "sleep".

Then the next day you get flaps 2 for a 13R KJFK departure...

We had it going out of FLL last night. We were going to Vegas, and at 163,000lbs were too heavy to use 28L at all, and could do 28R at Flaps 3, TOGA, and packs off.
