Abstract: A communication system and a method for transmitting data from an aircraft, the aircraft comprising at least one engine. A data collection and transmission unit is configured to collect and transmit data received from one or more locations in the aircraft, the data collection and transmission unit comprising at least one radio transmitter. At least one engine controller for the at least one engine is communicatively coupled to the data collection and transmission unit and configured to transmit, while the aircraft is airborne, engine data to the data collection and transmission unit, and, responsive to determining that the aircraft is on ground, cause the at least one radio transmitter to activate for transmitting the engine data from the data collection and transmission unit to at least one ground equipment.

Abstract: There is provided a blade angle feedback system for an aircraft-bladed rotor rotatable about a longitudinal axis and having an adjustable blade pitch angle. A feedback device is coupled to rotate with the rotor and to move along the axis with adjustment of the blade pitch angle. The feedback device comprises a body having position marker(s) embedded therein, the body made of a first material having a first magnetic permeability and the position marker(s) comprising a second material having a second magnetic permeability greater than the first. Sensor(s) are positioned adjacent the feedback device and configured for producing, as the feedback device rotates about the axis, sensor signal(s) in response to detecting passage of the position marker(s). A control unit is communicatively coupled to the sensor(s) and configured to generate a feedback signal indicative of the blade pitch angle in response to the sensor signal(s) received from the sensor(s).

Abstract: Systems and methods for configuring operation of an engine are described herein. A computer-readable label associate with the engine is read by a mobile device to obtain label information having at least one trim value for the engine encoded therein. The at least one trim value is extracted from the label information on the mobile device. The at least one trim value is wirelessly transmitted from the mobile device to a data transmission unit of the engine. The data transmission unit is configured for instructing an electronic engine controller to trim the engine with the at least one trim value during operation of the engine.

Abstract: A phonic wheel having a body and a tooth is disclosed. An embodiment of the phonic wheel includes a body that is configured to rotate about a rotation axis. The tooth is attached to the body. The tooth has a first axial end relative to the rotation axis, a second axial end opposite the first axial end, and a mid portion extending between the first and second axial ends. The mid portion has a substantially axially uniform height from the body. The first axial end has a greater height from the body than the height of the mid portion.

Abstract: Methods and systems for setting a target power of an aircraft engine are described herein. A power lever position is obtained. At least one flight condition indicative of a phase of flight of the aircraft is obtained. A maximum rated power of the engine is determined for one or more engine rating based on the phase of flight. The target power of the engine is set based on the power lever position and the maximum rated power of the one or more engine ratings.

Abstract: A system and method for controlling an aircraft propeller are provided. In anticipation of a condition in which a parameter related to an angle of a plurality of blades of the propeller reaches a value beyond a predetermined threshold, a first control signal is output comprising instructions to actuate a feather valve operatively coupled to an actuator configured to adjust the angle in response to hydraulic pressure, thereby causing the feather valve to provide the hydraulic pressure to the actuator and the angle to be adjusted for bringing the parameter towards the threshold. When the parameter reaches the predetermined threshold, a second control signal is output comprising instructions to hold the feather valve at a position in which the hydraulic pressure is withheld from the actuator, thereby causing the angle to remain unchanged.
