10 deg. of flaps, take off and short field. How (for us dummies) do you determine 10 deg. ?

10 deg. Of flaps in a 6 /6A for take off and for short field take off. How ( for us dummies) do you determine 10 deg. ?

One thousand one - one thousand two - one thousand three

That is what I use when in the air. When on the ground I move the aileron to full deflection on the left wing. Then I match the flap trailing edge to the aileron trailing edge.

As Steve says, matching the "down aileron" gives you approximately 15°. This is considered optimal L/D for take off.

You can also measure the flap angle and apply tape, paint pen, or permanant marker to the flap to show when the leading edge of the flap extends past the trailing edge of the wing. That'll give you a visual reference.
