|  Flap Degrees
I'll try to make this simple- What makes 20 degrees of flaps 20 degrees of flaps? For example....... On a 182T the first increment of flaps is 10 degrees. Why is that amount of flaps "10 degrees?" Do you understand my question  |

| Re: Flap Degrees
It nominally is because at "20 degrees" the flaps are deflected downward 20 degrees from their raised position - same thing for 10 degrees, 30 degrees, etc. The angular measurement is somewhat arbitrary because the reference line for measurement can be different places on the flaps, and there are several different types of flaps, some of which translate as well as pivot when they move. For each specific aircraft, the manufacturer will have performance data based on tests with the flaps at each setting. |

More to the point, the manfucture is not required to have the flap degree necessarily corrolate to anything at all, it is just a setting to be used. The actual specs only need to be part of the Mx manual, and they can use what ever datum they want to make the numbers work.

Also, in some aircraft, flap settings are in percentages. 0% is flaps retracted, 100% is full flaps.

Normally "10 deg of Flaps" means that the flap has moved 10 deg from the normal retracted chordline of the wing. However as Seagull noted there is no regulation requiring manufacturers to go by this standard. |

Furthermore, the correct puncticulation of the coronactory angle is dependant upon the existing platitudes of fuctunillity during takeoff and climb, and contoctotomyduring decentand landing. During taxi, the flap's extension promonation isdetermined by the former canvaction of the chord. Always referto your POH. |

Lloyd wasn't even speaking English, it just sounded close enough so we all thought it was pure brilliance. Well done!  |
