41. They are used during low speed, high angle of attack flight including take-off and descent for landing. 42. It is a high angle of fire sight used when the gunner is aiming at air targets. 43. A free-floating mechanism may increase static stability and provide safe recovery from high angle of attack evolutions. 44. We specialize in high angle , extreme terrain. 45. The high angle allows judges to see the position of every racer in relation to the others. 46. At high angles of attack, the wing tips remain unstalled allowing the aircraft to retain aileron control. 47. The one half wavelength design greatly reduced high angle radiation, thus solved the close in fading issues. 48. Flight with the NACA ducts proved troublesome at high angles of attack, restricting air flow to the engines. 49. The Vietnamese artillery commanders had miscalculated and had set up their cannons incorrectly, firing at excessively high angles . 50. High angle of attack protection may be lost and low energy ( level flight stall ) protection is lost.
