Abstract:
In an example, a method for on-board maintenance of an aircraft is described. The method includes measuring, by a pressure sensor, a pressure in a tube associated with an engine of an aircraft. The method also includes determining, by a control system and based on the pressure measured by the pressure sensor, that the tube is at least partially blocked by moisture. Additionally, the method includes, responsive to determining that the tube is at least partially blocked by the moisture, providing an alert signal from the control system to a flight deck of the aircraft. The method also includes, responsive to the alert signal, operating an actuation switch at the flight deck to actuate a valve to an open state. The method further includes, responsive to actuating the valve to the open state, supplying an inert gas from an inert gas supply to the tube to expel the moisture.
