This paper reviews the characteristics of a power line network as data communication medium and studies the challenges encountered when communicating over power wiring. This technology review has been done as part of feasibility study for using aircraft power-lines for data communication. Power-Line Communication is a term which describes the use of existing electrical lines to provide the medium for a high speed communications network. Power Line Communications is achieved by superimposing the voice or data signals onto the line carrier signal using an appropriate communication technology. Power Line Communications represent a potential simplicity for communications among different devices, because it does not need additional wires for connecting devices network together. Power line cables have been used as a communication medium for many years. However, because power line cables are not designed for communication, they pose major challenges for a modem designer.

The RTCA SC-230 committee began working on minimum operational performance standards (MOPS) for ice crystal detection using weather radar in 2018. The resulting MOPS document will be released in 2023. This paper presents the rationale, summarizes key requirements, and discusses means of validation for an ice crystal detection function incorporated in an airborne weather radar system.

Blockchain as a technology has been successfully deployed in the financial industry. As the technology continues to mature, there are opportunities to use this to solve operational challenges in Aerospace. One of the common use cases is replacing paper records as a proof of compliance with a blockchain enabled distributed ledger. Commonly available open source blockchain frameworks have security ingrained in the components. However, replacing paper records with a blockchain based distributed ledger will require investigation of potential risks involved in the end to end usage of this technology for records management. The objective of this paper is to elucidate potential risks in an aviation record management workflow environment enabled by blockchain and suggest requirements to mitigate the risks.
