WIP

AIR7063

This document provides guidance for establishing ECS for UA by primarily referencing existing AC-9 documents that apply with some indication how they need to be adapted. The document primarily addresses cooling requirements for UA equipment. Limited information is provided for ECS requirements for future UA that may carry passengers. The document does not intend to provide detail design guidance for all types of UA. This document only provides guidance related to environmental control of onboard equipment, cargo and possible animals and passengers. It does not pertain to the related ground stations that may be controlling the UA.

Environmental Control for Civil Supersonic Transport

2011-08-10

CURRENT

AIR746C

This document supplements ARP85, to extend its use in the design of ECS for supersonic transports. The ECS provides an environment controlled within specified operational limits of comfort and safety, for humans, animals, and equipment. These limits include pressure, temperature, humidity, conditioned air velocity, ventilation rate, thermal radiation, wall temperature, audible noise, vibration, and composition (ozone, contaminants, etc.) of the environment. The ECS is comprised of equipment, controls, and indicators that supply and distribute conditioned air to the occupied compartments. This system is defined within the ATA 100 specification, Chapter 21. It interfaces with the pneumatic system (Chapter 36 of ATA 100), at the inlet of the air conditioning system shutoff valves.

Fault Isolation in Environmental Control Systems of Commercial Transports

2011-06-20

HISTORICAL

AIR1266A

This SAE Aerospace Information Report (AIR) outlines concepts for the design and use of fault isolation equipment that have general application. The specific focus is on fault isolation of environmental control systems (ECS) in commercial transports. Presented are general fault isolation purposes, design principles, and demonstration of compliance criteria. These are followed by three design examples to aid in understanding the design principles. Future trends in built-in-test-equipment (BITE) design are discussed, some of which represent concepts already being implemented on new equipment.
