Scope
The primary purpose of a Propellant Transfer Unit (PTU) is to temperature-condition and weigh a specific amount of propellant, and transfer if to a vehicle propellant tank. A secondary purpose of a PTU may be to drain propellant from the vehicle tank and return it to the transfer unit when required. The transfer unit may also be used for flushing the vehicle fill lines and transfer unit with appropriate flushing fluids, followed with nitrogen for the purpose of drying the lines and weigh tank. The transfer unit may include provisions for helium purging of the propellant transfer tank and lines, ad supplying a blanket of helium pressure to the transfer tank. Each PTU consists of a piping system with appropriate propellant and pneumatic valves, regulators, relief valves, filters and a propellant pump. Various components such as a scrubber, bubbler, propellant cooler (heat exchanger), propellant weigh tank, weigh scale and a chiller may make up the balance of the assembly. The PTU is an integrated assembly with all components mounted on a common support frame. Protective covers are provided for those units which operate outside of a controlled environment area.

AGE-3 Aircraft Ground Support Equipment Committee
AGE-3 is the Aircraft Ground Support Equipment Committee that addresses all aspects of airport, ground support equipment and associated systems that interface or require compatibility with the aircraft. The objectives of the Committee are:
- Develop and maintain technical standards, specifications and reports related to aircraft ground servicing and in particular to:
- Airport Ground Support Equipment (GSE)
- Aircraft to GSE interface
- GSE operation, maintenance and operator training
- Airport facilities and systems that have a direct relationship to and interface with GSE
- GSE environment related issues, including noise and emissions.
- Provide a forum for exchange of technical information related to aircraft ground operations where issues can be addressed and resolved.
- Coordinate and harmonize worldwide standards development with CEN TC 274, ISO TC 20/SC9, IATA GSEE and other standardization groups.
- Promote the global use of high quality standards and practices within the aircraft ground servicing scope.
- Promote research and innovation in any topics related to the scope of the Committee.
Participants in the SAE AGE-3 include OEMs, ground handling companies, airlines, suppliers, consulting firms and other actors across the aerospace and defence industries.

* 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.
