This SAE Aerospace Standard (AS) establishes the specification for TTP communication protocol functionality as a core networking component for design of synchronous, time-triggered distributed real-time communication networks.
This document is referred to as the “base” specification, containing the generic specification of TTP communication protocol functionality, and frame formats, communication services and protocol state machines with transitions, TTP node operation, TTP network operation, distributed clock synchronization and error detection on the network layer.
The details described in this standard enable interoperable TTP controller implementations.
TTP is used in a variety of aerospace applications (for example, Boeing 787 power generation systems and environmental controls, cabin pressure systems for Airbus A380, Aermacchi M-346 FADEC…) and continues to attract significant cross-industry attention for commercial and defense applications.
The SAE standardization of TTP:
acts as an integration risk reduction mechanism
ensures compatible physical implementations
enables common test/maintenance equipment
leverages industry investments
ensures openness and enables multiple component and tool suppliers
and therefore reduces the overall cost and risk of applying this technology.
The SAE standardization based on TTP specification protects long-term system design investments, enables development of the COTS ecosystem, and minimizes sourcing risks for OEMs, integrators and system suppliers.

* 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.
