For example, you want to maintain 250 for as long as possible. That means you have to start slowing 2,500 feet above the airport. ATC wants 190 knots, start slowing 1,900 feet above the airport.
And with 1,000 hours in the Dash 8 and 145 each, flaps 15 for the Dash and flaps 45 for the 145 were the norms.

I went through the 145 program pretty early, and we were basically always doing flaps 22. In the sim and during SOE. Sometime in the past 6 months, the training department decided flaps 45 should be the norm.
If you went through early, you probably prefer flaps 22. If you've been through recently, you probably prefer flaps 45. We like what we're used to. It's that simple.
As people start going through recurrent, flaps 45 will become the norm throughout the airline
