| Mar 14, 2016 at 10:57 | comment | added | Peter Kämpf | @GdD Full flaps are designed for landing (high lift and high drag) and are almost never helpful for shortening the takeoff run. I overlooked that in the question and edited the answer. | |
| Mar 14, 2016 at 10:56 | comment | added | Peter Kämpf | @GdD: The biggest dependency is flap deflection angle. A split flap is a poor choice for short takeoffs because of its drag, yet for small deflections even this type of flap helps to shorten the takeoff run. The next dependency is flap type, and I assume that is what you meant by airplane type. Sure, other parameters like aspect ratio and sweep also play their part, but when you look at the same aircraft with and without flaps, the deflection angle determines whether those flaps can be helpful or not. For some types of flaps the helpful range of angles is rather small. | |
