Scope
This paper presents guidelines for development of a procedure for external software loading of an electronic engine control (EEC) for a commercial application, on-wing or in a qualified service shop. This paper makes the following assumptions:
-
a
The EEC is designed to accept external software loading.
-
b
The EEC is certified as part of an engine.
-
c
The support equipment is qualified in accordance with procedures set forth by the engine (and aircraft, if necessary) certifying authority if the EEC cannot detect an integrity violation of the loaded program.
-
d
The software to be loaded has been approved by the engine and aircraft certifying authorities.
-
e
One or more configurations of EEC hardware has been identified for each version of software which is to be loaded in the EEC.
It is appropriate to use these guidelines in the initial development phase, although the certification issues would not be applicable.
Approval as used herein means approval by the engine (and aircraft, if necessary) certifying authority. There are cases where the engine may commence certification activities and no specific aircraft application has been identified. In these cases, the aircraft certification authority should be notified of the EEC’s external software loading capability when the engine’s application is identified. The appropriate documentation can be delivered to the aircraft certifying authority at that time.
Rationale
After review of the subject material of this ARP, it is found that (1) its current content is extremely limited in scope relative to FADEC architectures in use today and (2) the material which might be added to modernize this document either is already found in other guidance or should be located elsewhere if it is thought to be of value.

Areas of interest will include, but not be limited to, the design, installation, operation and maintenance of engine control system components including metering components and actuators and the interface and communication methods for (A) Cockpit Displays, (B) Flight Control, ¿ Diagnostic and Health Monitoring Systems. Coordination with other SAE committees will occur to minimize redundant activities within the organization and maximize the benefit of additional recommendations and standards.

* 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.
