The B pumps run automatically with the Flaps out of 0. The logic is that it is a critical phase of flight.

When you put the flaps out of the 0 position the hydrolic pumps automaticaly turn on to open the gear doors. given you have the hydrolic switch in the auto position.

3 out of 6 work just fine for putting the gear down.

Not as much as I had hoped... I've gotten like 3 gear disagrees in this past month. I kept telling my captain to "Caution G/D" and she's like "Oh no, it'll work just fine." She finally figured out what I was talking about after the third.

So since I haven't heard the official word about the flap limitation.... what's the general consensus? If I'm at 210, can I slow to 200, drop the flaps, and speed back up? Or I guess all companies would be different.

No, I just found it an interesting topic to talk about rather than the same old topic of what airline is better than the other.

Sounds like fun, i like my EMB, no flaps will descend at 1800 FPM below 10,000, and can drop the first set of flaps at 250kts. Rocking out Amazon Jet!

Yeah its done it to me 3 out of 5 times. Now I just flip the HYD pumps on and it works like a charm. It scared me the first time it happened, but after a brief "holy crap" I reached over and put the flaps in and the gear came down properly.
