Uncrewed aircraft systems — Training for personnel involved in UAS operations
Scope: This document specifies the procedures for training personnel who will be involved in the operation of uncrewed aircraft systems (UAS).
This document defines:
knowledge, skill, attitude and qualification criteria required for UAS remote pilots (RP), remote pilot in command (rPIC) and UAS training organizations (UTO) that provide training to UAS remote pilots and other personnel involved in UAS operations;
training curriculum and contents for specific learning courses;
qualification and criteria for verification of achieved competence by the training organizations;
general procedures for providing training of UAS personnel.
NOTE 1 An UTO can include additional topics or learning objectives, such as when required by legally binding rules in the applicable jurisdiction.
NOTE 2 A UAS operator can also act as the UTO, providing that possible conflict of interest between training and operations is properly managed.

Quantum Computing - Roadmap for Post-Processing Software in Space
Scope: This document provides insights into post-processing software (PPSW) in space with the aim of coordinating standardization efforts.
For this purpose, the state of the art in PPSW development for space-based QKD systems, along with past experiences and best practices, is analyzed, and the general architecture of the PPSW is described for both space and ground segments.
Furthermore, the functional blocks for the PPSW, the information flow, and the corresponding interfaces for standardization and their hardware components are identified. A mapping of hardware to software components for standardization needs is provided. The distillation of secure keys and the creation of entanglement are addressed, though the latter is treated as more prospective due to current technological limitations.
Finally, a critical review of the components and interfaces is carried out to propose a standardization plan and priorities for PPSW in space-based QKD systems.

Unmanned aircraft systems — Training for personnel involved in UAS operations
Scope: This document describes the procedures for training personnel who will be involved in the operation of unmanned aircraft systems (UAS).
This document defines:
a) knowledge, skill, attitude and qualification criteria that are needed for UAS pilots and training organizations that provide training to UAS remote pilots and other personnel involved in UAS operations;
b) training curriculum and contents for specific learning courses;
c) qualification and confirmation criteria for the training organizations;
d) general procedures for providing training of UAS personnel; the requirements for a specific course as described in Annex A can be more restrictive in some cases.

Aerospace series - Circuit breakers, three-pole, temperature compensated, rated current 20 A to 50 A - Part 004: UNC thread terminals - Product standard
Scope: This document specifies the characteristics of three-pole circuit breakers, temperature compensated with a rated current from 20 A to 50 A, used in aircraft on-board circuits at a temperature between −55 °C and 90 °C at an altitude of 15 000 m max.
These circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action "trip-free" tripping
They will continue to function up to the short-circuit current.
