Abstract

A method is provided for operating a piston engine in an airplane in an emergency operating mode, in which a minimum power output of the piston engine is ensured in that an emergency operating mode is activated that is as much as possible independent of measured values of respective sensors provided for an operation of the piston engine, in which the measured values of the sensors are substituted with firmly specified values. A corresponding airplane is provided as well as to an emergency operation control unit for carrying out the provided method.

Claims

1. A method for operating at least one piston engine in an airplane in an emergency operating mode, in which a minimum power output of the at least one piston engine is ensured, the method comprising:

activating the emergency operating mode that is as much as possible independent of measured values of respective sensors provided for an operation of the at least one piston engine; and

substituting the measured values of the sensors with firmly specified values.

2. The method as recited in claim 1, further comprising storing the firmly specified values in a separate emergency operation control unit that is activated only during the emergency operating mode.

3. The method as recited in claim 1, switching respective actuators provided for an operation of the at least one piston engine into an emergency operating state.

4. The method as recited in claim 3, wherein the emergency operating state is a firmly specified state.

5. The method as recited in claim 1, further comprising activating the emergency operating mode by a button that is connected to at least one control unit.

6. The method as recited in claim 1, further comprising activating the emergency operating mode by a kick-down switch on a lever for controlling the airplane.

7. An airplane, comprising:

at least one piston engine; and

at least one electronic control system that is configured to control the at least one piston engine using at least one firmly specified value of an operating parameter when an emergency operating mode is activated.

8. An emergency operation control unit for operating at least one piston engine in an airplane, comprising:

an arrangement for operating the at least one piston engine, in the event of an activation of an emergency operating mode, in accordance with a method for operating the at least one piston engine in the airplane in the emergency operating mode, in which a minimum power output of the at least one piston engine is ensured, the method comprising;

activating the emergency operating mode that is as much as possible independent of measured values of respective sensors provided for an operation of the at least one piston engine, and

substituting the measured values of the sensors with firmly specified values.
