1. A slat for an aircraft wing, comprising: a leading edge defining a leading edge line connecting forward-most points of the slat and extending between a wing root end and an outboard end;a trailing edge defining a trailing edge line connecting aft-most points of the slat, extending between the wing root end and the outboard end, and being disposed a chord distance from the leading edge in a hingewise direction, wherein the chord distance between the leading edge and the trailing edge extends normal to the leading edge;an inboard edge comprising a first leg that extends from the leading edge to an intermediate point between the leading edge and the trailing edge, anda second leg that extends from the intermediate point to the trailing edge; andan outboard edge that extends from the leading edge to the trailing edge,wherein the second leg is disposed at an angle to the first leg, toward the outboard edge. 2. The slat according to claim 1, wherein the first leg defines a straight line. 3. The slat according to claim 1, wherein the second leg defines a straight line. 4. The slat according to claim 1, wherein the second leg is disposed substantially parallel to airflow when the slat is on an airplane. 5. The slat according to claim 1, wherein the first leg extends for no more than 90% of the chord distance. 6. The slat according to claim 1, wherein the first leg extends for at least 40% of the chord distance. 7. The slat according to claim 1, wherein the first leg extends between 40% and 90% of the chord distance. 8. The slat according to claim 1, wherein the first leg extends between 50% and 70% of the chord distance. 9. The slat according to claim 1, wherein the first leg extends for about 60% of the chord distance. 10. The slat according to claim 1, wherein the first leg extends for no more than 60% of the chord distance. 11. The slat according to claim 7, wherein the first leg extends for no more than 60% of the chord distance. 12. The slat according to claim 8, wherein the first leg extends for no more than 60% of the chord distance. 13. The slat according to 1, wherein the second leg extends for at least 10% of the chord distance. 14. The slat according to claim 1, wherein the first leg is parallel to the chord. 15. The slat according to claim 1, wherein the outboard edge is parallel to the chord. 16. The slat according to claim 1, wherein the first leg and the outboard edge are parallel to the chord. 17. The slat according to claim 1, wherein the second leg is substantially parallel to airflow when the slat is mounted on an airplane. 18. The slat according to claim 1, wherein the slat increases a lift coefficient when mounted on a wing of an airplane. 19. The slat according to claim 1, wherein the slat delays stall when mounted on a wing of an airplane. 20. An airplane with an inboard slat mounted on a wing, the slat comprising: a leading edge defining a leading edge line connecting forward-most points of the slat and extending between a wing root end and an outboard end;a trailing edge defining a trailing edge line connecting aft-most points of the slat, extending between the wing root end and the outboard end, and being disposed a chord distance from the leading edge in a hingewise direction, wherein the chord distance between the leading edge and the trailing edge extends normal to the leading edge;an inboard edge comprising a first leg that extends from the leading edge to an intermediate point between the leading edge and the trailing edge, anda second leg that extends from the intermediate point to the trailing edge; andan outboard edge that extends from the leading edge to the trailing edge,wherein the second leg is disposed at an angle to the first leg, toward the outboard edge. 21. The airplane according to claim 20, wherein the first leg extends for no more than 90% of the chord distance. 22. The airplane according to claim 20, wherein the first leg extends for at least 40% of the chord distance. 23. The airplane according to claim 20, wherein the first leg extends between 40% and 90% of the chord distance. 24. The airplane according to claim 20, wherein the first leg extends between 50% and 70% of the chord distance. 25. The airplane according to claim 20, wherein the first leg extends for about 60% of the chord distance. 26. The airplane according to claim 20, wherein the first leg extends for no more than 60% of the chord distance. 27. The airplane according to claim 23, wherein the first leg extends for no more than 60% of the chord distance. 28. The airplane according to claim 24, wherein the first leg extends for no more than 60% of the chord distance. 29. The airplane according to 20, wherein the second leg extends for at least 10% of the chord distance. 30. The airplane according to claim 20, wherein the first leg is parallel to the chord. 31. The airplane according to claim 20, wherein the outboard edge is parallel to the chord. 32. The airplane according to claim 20, wherein the first leg and the outboard edge are parallel to the chord. 33. The airplane according to claim 20, wherein the second leg is substantially parallel to airflow when the slat is mounted on the wing. 34. The airplane according to claim 20, wherein the slat increases a lift coefficient when mounted on the wing. 35. The airplane according to claim 20, wherein the slat delays stall when mounted on the wing. 36. The airplane according to claim 20, wherein the first leg defines a straight line. 37. The airplane according to claim 20, wherein the second leg defines a straight line.
