Aircraft Ground Deicing/Anti-Icing Processes

2024-04-29
WIP
AS6285F
This SAE Aerospace Standard (AS) establishes the minimum requirements for ground-based aircraft deicing/anti-icing methods and procedures to ensure the safe operation of aircraft during icing conditions on the ground. This document does not specify the requirements for particular aircraft models.NOTE: Refer to particular aircraft operator or aircraft manufacturer’s published manuals and procedures.The application of the procedures specified in this document are intended to effectively remove and/or prevent the accumulation of frost, snow, slush, or ice contamination which can seriously affect the aerodynamic performance and/or the controllability of an aircraft. The principal method of treatment employed is the use of fluids qualified to AMS1424 (Type I fluid) and AMS1428 (Type II, III, and IV fluids).All guidelines referred to herein are applicable only in conjunction with the applicable documents.

AVSC Best Practice for First Responder Interactions with Fleet-Managed Automated Driving System-Dedicated Vehicles (ADS-DVs)

2024-04-04
CURRENT
AVSC-I-01-2024
This AVSC best practice was first published in 2020 and has been revised to cast expanded role definitions, rearrangement of use cases in Section 4 based on severity of risk, re-creation of Table 4 in 5.4 as a checklist and moved to Appendix B, as well as clarification of sections, examples, and terms throughout the document. This document outlines interactions between first responders and ADS-DVs (SAE level 4 and level 5). It builds on earlier work done by the Crash Avoidance Metrics Partners (CAMP), detailing three types of interactions first responders may encounter: direct, indirect, and informational. In addition, a standardized framework with recommendations for an interaction plan is laid out for ADS developers, manufacturers, and fleet operators which may assist first responders in both emergency and non-emergency situations involving ADS-DVs.

Test Method for the Determination of Total Acidity in Polyol Ester and Diester Gas Turbine Lubricants by Automatic Potentiometric Titration

2024-03-18
CURRENT
ARP5088C
The test method describes the procedure for determination of the total acid number (TAN) of new and degraded polyol ester and diester-based gas turbine lubricants by the potentiometric titration technique. The method was validated to cover an acidity range of 0.05 to 6.0 mg KOH g-1. The method may also be suitable for the determination of acidities outside of this range and for other classes of lubricants.

Design of Aircraft Deicing Facilities

2024-02-21
WIP
ARP4902D
This document provides information and guidance material to assist in assessing the need for and feasibility of developing deicing facilities, the planning (size and location) and design of deicing facilities, and assessing environmental considerations and operational considerations associated with de-icing facilities. The document presents relevant information necessary to define the need for a deicing facility and factors influencing its size, location, and operation. The determination of the need for deicing facilities rests with Airports. Although this document intends to provide information to airport operator and deicing facility planner/designer, all stakeholders, including deicing service providers, should be involved in the development process.

Verification Process for Thermal Runaway Mitigation in Large Electrical Energy Storage Powertrain Systems in Normal Category Aircraft and Rotorcraft

2024-02-16
CURRENT
ARP7131
This SAE Aerospace Recommended Practice (ARP) is an industrial collaboration with regulatory bodies like the European Aviation Safety Agency (EASA) and the Federal Aviation Administration (FAA) to determine the worst-case credible thermal runaway (TR) condition (energy released and maximum temperature) for the design of an aviation large propulsion battery system to quantitatively verify TR in lieu of battery level RTCA DO-311A testing with protections disabled. The ARP considers the three stages of TR within a cell and defines the two critical temperatures for a specific cell design. These temperatures are key to understanding the layers of monitoring necessary to determine the severity of a TR event. Different trigger methods can be used to quantify the heating characteristics and resultant energy profile releases as a function of time.
