View Full Version : Flaps-Climb rate?

Hello,
Does one notch of combat flaps help with climb rate (ex: p-51) when the speeds get slower? It seems so but was just wondering.

Thanks,

Realistically flaps will ALWAYS reduce your best rate of climb speed and the best rate of climb achievable...especially split flaps. The reason being that they add lots of drag as well as lift.

I suppose it is possible that they may increase the climb gradient (the distance travelled divided by the height climbed), but given the amount of drag they generate I would need to be convinced.

They supply lift but that doesn't mean they increase rate of climb. Remember that rate of climb is also attributable to speed, and with flaps down your speed it reduced, meaning you can't achieve as good an angle of attack. Sure, they are great for getting height on takeoff or lowering stall speeds on landing, but other than that they aren't really used alot (a couple planes turn alot better with combat flaps, but not all do).
