This document is a guideline for format, structure and content for ground support equipment (GSE) technical manuals. This document focuses on requirements specific to the GSE industry and does not cover general technical publication practices. Additional standards for GSE and for manufacturer’s publications exist and may add requirements beyond what is covered in this standard. This may include EU Directive 2006/42/EC. This document is written in specific terms by intention, and conforms to recognized practices in the industry. When the word SHALL is used in this standard, it indicates a requirement that must be adhered to in total and does not allow for variance. When the word SHOULD is used, it indicates a recommended practice which allows the manual writer to use discretionary judgment. This document does not apply to electronic test equipment.
This Aerospace Information Report (AIR) is intended to be concerned with fleet programs rather than programs for individual units. Technical and administrative considerations in developing an approach to a program will be suggested. Organization of material possibly wanted in the form of a detailed specification for airline rebuilder communication is reviewed.
The emergence of electric Vertical Takeoff and Landing (eVTOL) air vehicles is transforming how people and freight are moved in short distances. This transformation has a profound impact on surrounding infrastructure necessary to provide Aircraft On Ground support for eVTOLs. The hover capabilities of eVTOLs have similar operating characteristics within terminal and uncontrolled airspace. However, the need to conserve battery energy via rapid approaches and departures affects terminal airspace management. To attract eVTOL operators, existing airports, landing zones, and vertiports are modifying their infrastructure to include fixed electric charging stations, additional taxiways, upgraded fire suppression systems, separate hangers, and capable MRO facilities. Augusta Regional Airport (KAGS) is the base airport for the annual Masters Golf Tournament which experiences five times the normal airport traffic and some 40,000 commuting patrons. eVTOLs can offset land traffic issues associated with commuters and supplies. Since KAGS is centroid to 32,000 square miles of territory void of major highways, basing eVTOLs can offer expedited transit services for people and goods which will have a profound impact on the economic viability and quality of life in the area.
The new 2600 Series 13-liter engine for off-highway machines will do more with less thanks to variable geometry turbocharging. Perkins announced in September its all-new engine series for off-highway applications, launching the 2600 Series 13-liter engine at a press event in London where Truck & Off-Highway Engineering was in attendance. Perkins states that the 2600 Series is intended for a wide array of off-highway applications including agricultural tractors, materials handling, construction, mining, aircraft ground support and other use cases. “As the off-highway industry advances toward a lower-carbon future, equipment manufacturers still face expectations for long-term productivity and reliability in the world's most-demanding work environments,” said Jaz Gill, vice president of global sales, marketing, service and parts. “The new Perkins 2600 Series engine platform demonstrates how we're leveraging our experience, intelligence and commitment to help OEMs navigate the energy transition with power solutions that deliver exceptional performance on the worksite.”
This SAE Aerospace Recommended Practice (ARP) covers the design and installation requirements for hydraulic systems (up to 8000 psig [56 MPa]) for ground support equipment (GSE). This ARP is derived from AS5440, which provides hydraulic system requirements for aircraft. The recommendations herein are primarily intended for GSE that exchange hydraulic fluid with the aircraft, such as hydraulic service carts, rather than GSE with non-interfacing hydraulic systems. The GSE may be mobile, portable, or stationary.
This SAE Aerospace Standard (AS) defines interface configurations for the ground air conditioning service connection on commercial transport aircraft. In addition, it defines the clearances required to accommodate the connection of ground air conditioning hose couplings. Two types of service connections are included. The Type A connection (Figure 1) is a slotted ring with integral locking pads and is comparable to the MS33562 connection. The Type B connection (Figure 2) is a flanged tube with external locking lugs (Figure 3). The Type B connection has the same interface dimensional requirements as the Type A connection.
The purpose of this specification is to provide airplane operators and tow vehicle manufacturers with: a General design and operating requirements pertinent to test and evaluation of towbarless tow vehicles. Specific design requirements are provided in ARP4852 and ARP4853. b Test and evaluation requirements. The results of these test evaluations will determine if the loads induced by the tow vehicle will exceed the design loads of the nose gear, or are within the aircraft manufacturer’s limits so that they do not affect the certified safe limit of the nose gear. The results of these test evaluations will also determine if a stability problem may occur during pushback and/or maintenance towing operations with the tested airplane/tow vehicle combination. This document specifies general test requirements and a test evaluation procedure for towbarless tow vehicles (TLTV) intended for pushback and maintenance towing only. It is not meant for dispatch (operational) towing (see definitions in 2.3). Dispatch towing imposes more fatigue cycles on nose gears and structure due to additional passenger, cargo, and fuel loads, as well as more starts, stops and turns. Airframe manufacturers may require submittal of test results for evaluation or may provide information which allows TLTV manufacturers or airlines to self-test or evaluate the towbarless tow vehicles themselves. Refer to the airframe manufacturer’s documentation for evaluation requirements and detailed testing procedures that may be different than contained in this specification. In the event of a difference in requirements, airframe manufacturer documentation takes precedence over this Recommended Practice. TLTV manufacturers may elect to prepare and provide customers or regulatory agencies with a “Certificate of Compliance” or equivalent documentation as evidence that successful testing and evaluation of a specific tow vehicle/airplane type combination has been completed in accordance with this ARP and/or the applicable detailed airframe manufacturer’s documentation. This certification will allow usage of the vehicle on specifically designated airplane model types. The certificate should be established under an appropriate quality control program meeting the requirements of ISO 9000 Series or equivalent. This specification requires that the TLTVs under consideration be maintained and operated in a serviceable condition. In addition, the vehicle to airplane interface protection system shall be calibrated periodically. This information is defined in ARP5284 and ARP5285.
