Flaps on when reaching 250 knots


Recommended Posts

Leave the flap lever in the Auto/Down position and then the flaps will automatically extend/retract when you pass 250 Kts. That's already implemented.

Is it recommended to leave the switch in auto/down during normal flight?

No, it is advised to manually retract the flaps after take off. The auto retraction is just flaps overspeed protection, not a convenience feature.

Understood. Thanks.

Although I did notice at 40k+ feet the flaps helped me maintain speed at a lower power setting. So the extra lift and subsequent lower AoA must have outweighed the extra drag from the flaps. It was weird because the plane slowed down, dropped flaps, started speeding up again and when the flaps raised again it started slowing down.

You were too heavy, too high - in either configuration it's not optimal.

Too slow really. I was up high hunting migs 😄 but got stuck heads down too long and didn't notice that I had been nose high and lost all my speed.
