Background

    NTSB Recommendation A-92-89 recommended manufacturers of integrated 
flight guidance and control systems be provided additional information 
in the Airplane Flight Manual (AFM) and training information regarding 
systems failures. The FAA's response to the recommendation includes the 
revision to AC 23.1309-1A that would include additional guidance to 
needed warning and procedural information for complex integrated 
systems for inclusion in the AFM. In the process of revising this AC, 
the policy and guidance for environmental and atmospheric conditions, 
and software assessment, are also updated.

    Issued in Kansas City, Missouri, October 3, 1994.

Acting Manager, Small Airplane Directorate, Aircraft Certification 
Service.
