Hydrogen Fueling Stations for Airports, in Both Gaseous and Liquid Form

AIR8466 (Current)

11/11/2024

Surrogate Basic Safety Messages for Testing and Evaluation Purposes Only

J2945/8_202411 (Current)11/06/2024

This document includes the initial recommendations for a V2X-equipped host vehicle (eHV) or Roadside Equipment (RSE) that can broadcast a surrogate basic safety message (SBSM) on behalf of an unequipped remote vehicle (uRV). This document is published for testing only, using a Test PSID (e.g., 0x7f) and not the PSID used by SAE J2945/1 and SAE J3161/1 for standard basic safety message (BSM) transmission (0x20). The basic principle is that the host system of the V2X capable device, whether on a host vehicle or an RSE, can determine whether detected vehicles are V2X enabled or not, and if not, formulate and broadcast messages on their behalf that describe their status to other V2X enabled devices. This document is based extensively on the V2V safety communication requirements in SAE J2945/1 and SAE J3161/1 and the supporting message set details in SAE J2735. The initial version of this document is an information report. If feedback from implementations, testing, and simulation becomes

Assessment of Electric Engine Failures Leading to LOPC

AIR7130 (Current)

10/21/2024

This document proposes a method to demonstrate compliance to engine certification rules requiring tolerance of the control system to single failures leading to Loss of Power Control (LOPC) or Loss of Thrust Control (LOTC) for electric or hybrid engines. At issue 1, the document was developed to address only fully electric engine configurations targeting single engine CS/part 23 level 1 and 2 aircraft applications. The methodology proposed herein is based on an alternative definition of Loss of Power Control (LOPC) proposed by EASA, the FAA, TCCA, and ANAC in a joint Decision Document. It is therefore only applicable to projects which elect to implement this authority-proposed alternative definition. Other approaches for the demonstration of compliance of electric engines to control system single fault tolerance requirements, including approaches based on legacy practices applicable to piston engines, remain possible. They are, however, outside of the scope of this document. Future

Rotorcraft Turboshaft Engine Idle Power Scheduling

AIR4121 (Current)

10/11/2024

The purpose of this SAE Aerospace Information Report (AIR) is to provide rotorcraft and engine designers with a better understanding of turboshaft engine idle power characteristics and objectives to be considered in the design and integration process. For the purpose of this document, idle is the lowest suitable steady-state power setting, most commonly corresponding to a gas generator speed setting or range. In general, a lower engine idle setting is desired by the airframer to reduce noise, fuel consumption, and main rotor downwash when on the ground and to reduce the size requirement of a rotor brake system. In contrast, the engine manufacturer generally prefers a higher engine idle setting, as operation further away from the engine design speed involves more challenges in operability and mechanical design. A variety of rotorcraft and engine factors are described for consideration. Some typical engine power and torque trends are presented for illustrative purposes. The information

Lane Departure Warning Systems: Information for the Human Interface

J2808_202406 (Current)

06/26/2024

The lane departure warning (LDW) system is a warning system that alerts drivers if they are drifting (or have drifted) out of their lane or from the roadway. This warning system is designed to reduce the likelihood of crashes resulting from unintentional lane departures (e.g., run-off-road, side collisions, etc.). This system will not take control of the vehicle; it will only let the driver know that he/she needs to steer back into the lane. An LDW is not a lane-change monitor, which addresses intentional lane changes, or a blind spot monitoring system, which warns of other vehicles in adjacent lanes. This informational report applies to original equipment manufacturer and aftermarket LDW systems for light-duty vehicles (gross vehicle weight rating of no more than 8500 pounds) on relatively straight roads with a radius of curvature of 500 m or more and under good weather conditions
