Environmental Control System Contamination

2018-06-14
WIP
AIR1539C
This publication will be limited to a discussion of liquid and particulate contaminants which enter the aircraft through the environmental control system (ECS). Gaseous contaminants such as ozone, fuel vapors, sulphates, etc., are not covered in this AIR. It will cover all contamination sources which interface with ECS, and the effects of this contamination on equipment. Methods of control will be limited to the equipment and interfacing ducting which normally falls within the responsibility of the ECS designer.

Air Conditioning Systems for Subsonic Airplanes

2018-06-14
WIP
ARP85G
This SAE Aerospace Recommended Practice (ARP) contains guidelines and recommendaitons for subsonic airpolane air conditioning systems and components, including requirements, design philosophy, testing and ambient conditions. The airplane air conditioning system comprises that arrangement of equipment, controls and indicators that supply and distribute air to the occupied compartments for ventilation, pressurization, and temperature and moisture control. The principal features of the system are: a. A supply of fresh air from at least two sources with independent control valves b. A means for heating c. A means for cooling (air or vapor cycle units and heat exchangers) d. A means for removign excess moisture from the air supply e. A ventilation subsystem f. A temperature control subsystem g.

Gland Design: Nominal 3/8 in Cross Section for Custom Compression Type Seals

2018-06-13
WIP
AS4832A
This SAE Aerospace Standard (AS) offers gland details for a 0.364 cross section gland (nominal 3/8 in) with proposed gland lengths for compression type seals with two backup rings over a range of 8 to 20 in diameter. A dash number system is proposed similar to AS568A. A 600 series has been chosen as a logical extension of AS568A and the 625 number has been arbitrarily chosen for the initial number. (Both 300 and 400 series begin with 325 and 425 sizes.) Seal configurations and design are not a part of this document. This gland is for use with custom compression type seals including, but not limited to, O-rings, T-rings, D-rings, etc.

CURRENT
AS5134B
This SAE Aerospace Standard (AS) provides minimum performance and design standards for a handheld, high-intensity, flashing Aviation Visual Distress Signal (AVDS) based on light-emitting-diode (LED) technology operating simultaneously in visible (white) and near infrared (NIR) spectra designed to facilitate location and rescue of aviation accident/ditching survivors in open sea conditions.

Aircraft Inflight Ice Detectors and Icing Rate Measuring Instruments

2018-06-11
WIP
AIR4367B
This document provides information regarding ice detector technology, design and operating requirements. The SAE document AS5498 provides detailed information regarding the requirements, specifications, qualification, and certification of icing detection systems. This document is not meant to replace AS5498 but to enhance it by considering unique aspects of sensing technology and in particular those that may not be certificated at the time of this revision. To that end an effort has been made not to duplicate information contained in AS5498. Icing rate information is included where applicable. The primary application is associated with ice forming on the leading edges of airfoils and inlets while the aircraft is in flight. Information related to detection of ice over cold fuel tanks and icing at low velocity operation is included. The material is primarily applicable to fixed-wing aircraft. Unique requirements for engine inlets and rotorcraft are also provided.

Rationale for Replacement of Pyrotechnic Signaling Devices in Survival Kits on Transport Category Aircraft Life Rafts and Slide-Rafts

2018-06-11
CURRENT
AIR5690A
This SAE Aerospace Information Report (AIR) identifies the risks and dangers associated with the carriage and use of pyrotechnic signaling devices in transport category aircraft life rafts and slide/rafts, and provides a rationale for allowing the use of alternative non-pyrotechnic devices authorized by FAA/TSO-C168. These devices offer an equivalent level of safety while eliminating flight safety risks, enhancing survivability of aircraft ditching survivors, reducing costs, eliminating dangerous goods transportation and handling issues, and reducing environmental impact of dangerous goods disposal.
