| 5722615 | Transport airplane with front empennage Airplane (1) including a mainplane (3), elevator aerodynamic surfaces (4) and a front canard empennage adjustable in orientation. This airplane includes: a device for calculating (14) continuously receiving measurements: of the speed (V) of the airplane with r... | 03/03/1998 |
| 5096146 | Apparatus and methods for controlling commanded operation of an aircraft within a predetermined flight parameter limit A controller for generating a bank angle limit for an aircraft during takeoff with an nonoperational engine. The controller operates so that there are minimum and maximum bank angle limits. Between these minimum and maximums, there is a linear relationshi... | 03/17/1992 |
| 5017089 | Propeller speed governor having a derivative inhibit at high flight speeds A propeller speed governor having a derivative feedback of propeller speed and having a means such as a switch to open the derivative feed back loop when airspeed exceeds a predetermined amount is shown and described. This derivative inhibit is used to pr... | 05/21/1991 |
| 4042193 | Safety device for aircraft doors or hatches A door or hatch operating mechanism is blocked by a bolt when the aircraft moves in that dynamic pressure is sensed by a spring biased displaceable large piston moving a small piston which acts on a hydraulic link acting, in turn, on another spring biased... | 08/16/1977 |
