Abstract: A dual-mode turret system includes a turret base operable by a motor drive of the turret system, a cylindrical sleeve secured to the turret base, a mounting cylinder disposed in the cylindrical sleeve, and a frame secured to the mounting cylinder, wherein the frame is adapted to hold a weapon. The dual-mode turret system also includes a locking apparatus that when engaged prevents the mounting cylinder from rotating independently of the cylindrical sleeve, a controller, and an input device coupled to the controller. Rotation of the frame is manually adjustable when the locking apparatus is disengaged, and the rotation of the frame is adjusted by the controller in response to commands received from the input device when the locking apparatus is engaged.

Abstract: Visual altitude alerting indicator for the altimeter of an aircraft, manually settable at "Before Landing Check List" to alert the pilot through visual cues to the required safe altitudes he must remember to prevent flying below prescribed safe altitudes, and to the altitude where the pilot must apply power to level when landing. The indicator requires no electronic assistance or audio alarms that might confuse the pilot over the many audio alarms presently used on aircraft. The alerting indicator consists of a ring concentric with the pivot for the hands of the altimeter and center of the dial therefor and adjustably movable about the dial and has a series of indicating altitude pointers to be adjusted relative to the dial at "Before Landing Check List" to alert the pilot through visual cues to the altitude he has to remember to prevent flying below prescribed safe altitudes when landing.
