Airline passenger satisfaction is important for airline operation service quality management. When airline companies carry out advertisement campaigns or plan a marketing strategy, the resources and budgets are not unlimited. Thus, an airline can only focus on improving a few factors that drive passenger satisfaction. To understand the key satisfies for the young and the old adults, respectively, we leverage five airline passenger satisfaction methods to identify the key factors that explain the airline service satisfaction of different passengers. In particular, we investigate and compare the ridge and the Lasso regularization in terms of the resulting model’s sparsity and computational efficiency. The top three important factors that influence the old’s satisfaction are departure and arrival time convenience, legroom service, and baggage handling. Our findings indicate that the young people place a higher value on entertainment, while the old adults place a higher value on usefulness

Next-gen swarm CubeSats’ synchronization and re-programmability

2022-26-116105/26/2022

The increasing need for interstellar data has increased the deployment of satellites in space, thereby increasing the space debris, also resulting in unnecessary costs. CubeSats have been gaining scads of attention worldwide for their affordability and ease of construction by the educational community. To further enhance this it is imperative for a simple and reliable communication technique and its ability to work on robust missions by enabling CubeSats in intelligent ways. The paper proposes a technology that can reduce the costs by deploying CubeSats and improving their lifetime and number of missions using TinyML and reprogrammability capabilities. Swarms of CubeSat deployed for extraterrestrial missions can be synchronized, without having any ground support with the help of onboard ML algorithms. CubeSats, being cost-effective and resource-efficient, its life-expendability can come as an added advantage. Hence, the paper also proposes the use of TinyML for power optimization and

Aircraft Ground Deicing/Anti-Icing Quality Management

AS6332A (Current)

07/29/2021

This document establishes the general requirements for the quality management of aircraft ground deicing/anti-icing systems and processes. It covers the areas of: Quality system, documentation, and control of records; Management responsibility; Resource management; Product realization; and Measurement, analysis, and improvement. This document defines these areas and their key aspects so they can be practically managed, and that deicing operations can become safer with time. In alignment with AS6285 and AS6286, the primary focus of this standard is on the deicing/anti-icing of aircraft using deicing and anti-icing fluids.

Laboratory Viscosity Measurement of Thickened Aircraft Deicing/Anti-icing Fluids with a Viscometer

AS9968A (Current)

07/23/2021

This document describes a standard method for measuring the viscosity of thickened (AMS1428) Type II/III/IV Aircraft Deicing/Anti-icing Fluids. The determination of viscosity for a Non-Newtonian fluid is very sensitive to shear and differences in sample chamber geometry. Even slight differences can have a large effect on measurement results. The test parameters and associated error for this standard are applicable to the Brookfield LV viscometer. A Brookfield LV or equivalent viscometer shall be used. To be considered equivalent, an alternate viscometer must demonstrate statistically equivalent performance, i.e., accuracy and precision when testing thickened (AMS1428) fluids using the same test parameters and conditions.Test parameters and conditions outside of the ranges described within this standard may be used only if they meet minimum limits for precision and accuracy established for the Brookfield LV viscometer. To compare viscosities, the same test parameters and conditions

Aircraft Tow Bar

ARP1915E (Current)04/08/2021

This SAE Aerospace Recommended Practice (ARP) specifies dimensional and physical requirements of tow bar connections to tractor and aircraft (see Figure 1). It is applicable to all types of commercial transport category aircraft tow bar. The purpose of this SAE Aerospace Recommended Practice (ARP) is to standardize tow bar attachments to airplane and tractor according to the mass category of the towed aircraft, so that one tow bar head with different shear levels can be used for all aircraft that are within the same mass category and are manufactured in compliance with AS1614 or ISO 8267.

Digital Data Standards in Aircraft Asset Lifecycle: Current Status and Future Needs

2021-01-0035

03/02/2021

The aerospace ecosystem is a complex system of systems comprising of many stakeholders in exchanging technical, design, development, certification, operational, and maintenance data across the different lifecycle stages of an aircraft from concept, engineering, manufacturing, operations, and maintenance to its disposal. Many standards have been developed to standardize and improve the effectiveness, efficiency, and security of the data transfer processes in the aerospace ecosystem. There are still challenges in data transfer due to the lack of standards in certain areas and lack of awareness and implementation of some standards. G-31 standards committee of SAE International has conducted a study on the available digital data standards in aircraft asset life cycle to understand the current and future landscapes of the needed digital data standards and identify gaps. This technical paper presents the study conducted by the G-31 technical committee. This paper reviews the data being

High-Fidelity Sonic Boom Propagation Tool

TBMG-3848402/01/2021

The primary challenge with supersonic flight remains the mitigation of the sonic boom to levels that will be acceptable to humans on the ground. As industry progresses towards realizing a commercial supersonic aircraft, the push from regulators to reduce noise levels has intensified. Innovators at NASA Langley Research Center have developed a system for predicting sonic boom propagation of supersonic aircraft. The sBOOMTraj tool enables efficient computation and mitigation of sonic boom loudness across the entire duration of a flight mission.

Charger for Battery Powered Ground Support Equipment

ARP1816D (Current)09/23/2020

This SAE Aerospace Recommended Practice (ARP) describes three general types of Ground Support Equipment (GSE) battery chargers. The battery charger typically requiring up to 8 hours to recharge a 100% discharged battery, hereafter called “Conventional Charger.” A charger, hereafter called “Opportunity Charger,” which has the ability to charge at a slightly faster rate than a conventional charger. A charger, hereafter called “Fast Charger,” which has the ability to charge at a much faster rate than a conventional charger. Recommendations that apply to all types will refer generically to “charger.”
