Aircraft Ground Air Conditioning Service Connection

2012-12-05
CURRENT
AS4262B
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.

Aircraft Maintenance Jacks - General Requirements

CURRENT
AS4775B
This document covers the general requirements for hydraulic aircraft jacks. It can be applied to tripod, unipod, and axle jacks that may be used on open ramp areas as well as in the aircraft hangar. Throughout this Aerospace Standard, the minimum essential criteria are identified by the key word “shall”. Recommended criteria are identified by use of the key word “should”. Deviation from recommended criteria should only occur after careful consideration and thorough service evaluation have shown alternate methods to provide an equivalent level of safety. The term “vertical load” throughout this Aerospace Standard is defined as the force imposed on the aircraft jack at the airframe jack point.

CUSHION TOW HITCHES TEST

1992-08-18
HISTORICAL
AIR1353A
The main purpose of this test was to determine the application advantages of cushion tow hitches in comparison to the commonly used rigid tow hitch type fitted on heavy aircraft towing tractors. As diverse opinions emerged about its suitability since the introduction on the market of this new tow hitch type, it was intended to physically measure and evaluate the damping capability of this cushioned tow link when applied in practice.

CURRENT
ARP836C
This SAE Aerospace Recommended Practice (ARP) is broken into various categories for convenience and ease of identification. It is the purpose of this document to provide certain criteria for the design and selection of stairways, for the boarding of passengers onto an aircraft. The criteria presented are limited to those factors which affect the safety of the passengers and are coordinated, where applicable, with the practices of the architectural profession, with respect to the design of stairways. The recommended practices are applicable to both mobile variable-elevation type stairways and to fixed-elevation stairways of the type built into an aircraft fuselage.

ARP1801A
The scope of this SAE Recommended Practice covers specialized internal combustion engine powered equipment used in support of aircraft operations. The equipment may be self-propelled, truck mounted, trailer mounted, skid mounted or stationary. It does not include construction equipment or equipment designed primarily for operation on highways or within factories or building areas. NOTE: Equivalent methodology is provided in (CEN) EN 1915-4, Aircraft ground support equipment - General requirements - Part 4: Noise measurement methods and reduction, to be used for measurements conforming to the EU Machinery Directive

SOLID-STATE FREQUENCY CONVERTER 400 HERTZ, 3-PHASE OUTPUT

1989-09-01
HISTORICAL
ARP1940
This specification covers the requirements for solid-state frequency converters with 480 [or 380] V 3-phase, 60 [or 50] Hz input and 115/200 V, 3-phase, 400 Hz output capable of powering aircraft type loads requiring MIL-STD-704D quality power. The frequency converter shall be a self-contained unit suitable for the environment of intended use. Typical applications include dedicated use at passenger loading bridges (mounted under the bridge in telescoping bridge applications or fixed installation at base of stationary type loading bridges) with weatherproof enclosures or hangar/lab use where indoor fixed or portable units can be used.
