Scope
This SAE Aerospace Information Report (AIR) has been compiled to provide information on hydraulic systems fitted to commercial aircraft.
Data has been provided for following aircraft types:
-
a
Wide body jet airliners
-
b
Narrow body jet airliners
-
c
Turboprop/commuter aircraft
-
d
Business jet aircraft
The airliners that have been included in this document are generally in operational service with either airlines or cargo operators. Information on aircraft that have been retired from in-service use has been included for reference purposes. No information is presented for aircraft that are currently being developed.
The following information is provided for each aircraft
-
Design requirements: Governing airworthiness regulations
-
System pressure: Fluid power system operating pressure
-
Hydraulic fluid: Type of fluid the hydraulic system uses
-
Number of hydraulic systems: Number and identification of independent hydraulic systems
-
System temperature: Minimum and maximum design operating temperatures
-
Main hydraulic pump data: Flow, pressure, displacement
-
Auxiliary pump data: System auxiliary pump or back-up data
-
Hydraulic motor data: System hydraulic motor requirements
-
Accumulator data: Usage, volume and precharge requirements
-
Reservoir data: Type, volume and pressure
-
Relief valve data: Usage, crack and reseat pressures, rated flow
-
Filtration data: Usage, filtration rating
-
Tubing data: Materials, sizes, wall thicknesses
-
Fitting data: Type, size range, material
-
Schematic diagram: System architecture, services supplied
Rationale
AIR5005 has been updated to Revision A for the following reasons:
-
a
Details of additional commercial aircraft hydraulic systems have been provided
-
b
Some business jet aircraft have been added
-
c
Update of references called up in the document

Issuing Committee
A-6A1 Commercial Aircraft Committee
The Commercial Aircraft Panel is responsible for the development of standards and recommended practices related to the integration of fluid power and actuation technologies into commercial air vehicles. The Panel provides a forum for aircraft manufacturers, suppliers, airworthiness regulatory engineers and operators to exchange technical information and discuss regulatory updates, recent technology developments, lessons learned, and issues related to system development and in service operation.
Reference
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
