something as simple as waxing your aircraft regularly. (it will decrease parasite drag) it may allow your aircraft to fly even up to 3 knots faster.

I always wondered, is that really so much ?

[@erich930]

The two big factors that affect the speed at which the critical angle of attack is exceeded are weight (obviously) and G forces. Higher weight or G forces increase the stall speed, and lower weight or G forces decrease the stall speed. High-lift devices and other aerodynamic features may also come into play, but this is the most basic physics you can apply even to a paper airplane.

vortex generators can reduce Vs and increase critical α

[@TheOchoCinco]

weight, weight distribution, snow,ice, frost, turbulence increases stall speed

[@Ali-fx6qp]

Power and flaps Power by increasing the thrust thus lift, and flaps by tilting the nose more downward but the airplane will stall in less aoa.

Can someone answer me, if (as defination) aoa is angle between relative wind and wing's cord then how airspeed change AoA while you don't change angle of your wings as physcially ?

[@Onlyonemash]

How about if we extend the trim tabs as that would push the aileron downwards and put the airplane to a straight level flight.

[@darrelmiller2609]

That depends on a lot of factors with weight being one of them. The heavier the aircraft the greater the AOA or The airspeed needs to be. Remember this though.... when ever the AOA is increased there is a portion of the weight vector shifted closer towards the drag vector.

@@user-cy7oz8vm4h The AOA increases because the effective chord line, which runs from the leading edge of the wing to the trailing edge of the flap, pivots up

[@davidgerlach1132]

Smaller wing load could reduce stall speed?

[@zarmril]

I have a question. Saying that "flaps decreases stall speed" may not be true? A certain amount of flaps can increase lift, at the expense of drag. However, in this case, the ratio between lift generated and induced drag is so that more lift is generated than drag is created. But if flaps were extended to a point in which induced drag was greater than lift generation, wouldn't stall speed thereby be increased since more lift is required to maintain an altitude? Ah, I just answered my own question. In a C172, stall recovery procedure is to have flaps no greater than let's say 20 degrees. This is because greater than 20 degrees generates more drag than lift, which can cause a secondary stall if you are not able to trade altitude for airspeed. Right?

[@youpeppe124]

U have no lift without incrementing drag. So the flaps do increase lift at any configuration but because of drag it's not convenient to use them until you are landing and you actually need that drag to slow down and to increase also the Vz (descent). In fact if you use more than 10° flaps for Takeoff you will have more lift for sure and reduce the ground roll, but as soon as you lift off the drag will cause you not to climb as easily as you do without flaps. In a go-around one of the things you do is infact retract flaps once the speed is appropriate because as flaps retract stall speed increases. Hope that helps

[@erich930]

The opposition force to drag is thrust, not lift. Not enough *thrust* is the reason you bring the flaps up for a stall recovery.

[@clayton4115]

Reduce the aoa will reduce stall speed

[@tionormanw]

It depends on what is your intention. With the maksimum takeoff weight you want to increase lift and gain higher altitude and reduce the stall speed; you just need to set your Flaps for takeoff setting and put your speed on Vy or Vx. Or, reduce your weight.❤

[@loutsont2985]

Not at once as clear to me as your other topics. Not always sure weather 'stall speed' is 'actual-', 'inevitable/laws of physics-' or 'wanted by pilot-' stall speed.

[@erich930]

I believe the term "stall speed" on its own is a little misleading. It implies that speed has something to do with a stall, which really it does not. I would say this video is "inevitable/laws of physics."
