Independent Suspension Drive Unit Spin Loss and Efficiency Testing
2020-12-01
WIP
J3243
This recommended practice describes a spin loss and efficiency test procedure for Independent Drive Units (FDU & RDU) used in light-duty vehicles. The test procedure is conducted on an axle test rig. The test matrix determines the spin loss and efficiency values at three mileage conditions of the axle and utilizes an accelerated break-in procedure.

Landing Gear Based Weight and Balance Systems
2019-04-18
WIP
AIR6941
This document outlines historical systems which have used the landing gear as a sensor or installation point for full aircraft weight and balance systems. A number of systems have been developed, installed, certified, and placed in service but few systems remain in regular use. The document will capture the history of these systems, reasons (where known) for their withdrawal from service, and lessons learned.

Aerospace Electrical Power System Stability
2018-09-10
WIP
AIR8445
EPS stability is an essential property that defines EPS ability to provide secure operation under required range of operation scenario. Power system stability is defined as “the ability of an electric power system, for a given initial operating condition, to regain a state of operating equilibrium after being subjected to a physical disturbance, with most system variables bounded so that practically the entire system remains intact”. This is applicable for AC and DC systems and has to address steady state conditions, transient conditions as well as high power loads connection / disconnection on the network.

Test Method for Catalytic Carbon Brake Disk Oxidation
2013-12-04
WIP
AS6289
The scope of the test method is to provide stakeholders including fluid manufacturers, brake manufacturers, aircraft constructors, aircraft operators and airworthiness authorities with a relative assessment of the effect of deicing chemicals on carbon oxidation. This test is designed to assess the relative effects of runway deicing chemicals by measuring mass change of contaminated and bare carbon samples tested under the same conditions.

Performance based packaging standard for lithium batteries as cargo on aircraft
2016-03-18
WIP
AS6413
This standard is intended to demonstrate and document the control of the potential hazards from lithium cells or batteries (UN 3090 and 3480) when transported as cargo on aircraft. [still need to identify if we are addressing global (external fire) or local (battery internal failures)] This standard addresses the need to control the hazards which might arise from a failure from an individual cell by containing the hazards within the package. This specific hazards addressed within this standard are: • Uncontrolled fire • Rapid overpressure pulse within compartment

Performance based package standard for lithium batteries as cargo on aircraft - Oven Test
2020-09-01
WIP
AS6413/1
This category specification provides a minimum performance standard that may be used for mitigation means, in addition to the foundation specification (AS6413), to provide external fire thermal threat capability which supports the safe shipment of lithium batteries as cargo on aircraft. This slash sheet provides information and testing to assist or augment the performance of the packaging used for shipping of lithium batteries. If protective equipment and measures are used, the performance of the battery package under the challenge of external heat and fire may be improved and enhanced.
