Abstract: A method and apparatus for tactile cueing of aircraft controls (21) is disclosed. The apparatus of the present invention warns pilots of approaching limits on certain aircraft performance parameters. The most common warnings are for rotor speed exceeding a moving limit. The present invention uses tactile cueing through the collective stick (21). Tactile cueing means that the pilot does not need to scan the intruments to ascertain proximity to the aforementioned limits. Instead, the pilot can operate the aircraft within proper limits by touch, while maintaining situational awareness outside of the cockpit (20). The method and apparatus of the present invention provides customary friction resistance up to a limit position that is continuously updated. According to the present invention, continued motion of the collective (21) in a direction beyond that limit position results in a breakout force and an increasing resistive force.

Abstract: A drilling device has a carriage (1) on which a drilling member (22) can be removably mounted. In a receiving region, the carriage (1) has a tightening lever (4) that can be swiveled, with its first end area having a tightening surface (5) that interacts with a clamping surface (21) of a connection region of the drilling member (22). The second end area of the tightening lever (4) interacts with a tightening element (9) that keeps the tightening lever (4) under tension of a spring so that the drilling member (22) is firmly pressed against the carriage (1). Using the two release levers (15), the tightening element (9) can be moved into a release position in which the tightening lever (4) can be swiveled into the release position and the tightening element (9) lies against a retention surface (13) on the tightening lever (4). When a drilling member (22) is secured on the carriage (1), the tightening lever (4) is automatically swiveled into a tightened position and locked the tightening element (9).
