Discussion of Comments

A notice of proposed policy was published in the Federal Register on August 30, 2002 (67 FR 55913). One (1) commenter responded to the request for comments.


In the past several years, new aircraft designs have introduced new technologies. These technologies are being combined and used in novel ways and may represent significant challenges with respect to the acceptability of the flightcrew interfaces and aircraft airworthiness.

Honeywell Primus Epic® Systems are an avionics suite consisting of single or multiple racks/cabinets with circuit cards or modules that plug into the cabinets. Each rack/cabinet is configurable in that the number of modules can vary in each cabinet; the functions loaded into the cards can vary considerably, and there can be multiple racks/cabinets per aircraft. The functionality of the system is determined by the software loaded into the circuit cards. All the software on these circuit cards can be field-loaded, that is, loaded into the Honeywell Primus Epic® modules without removing the equipment from the aircraft.

The final policy establishes guidance for the certification of Honeywell Primus Epic® Systems.

The final policy, as well as the disposition of public comments received, is available on the Internet at the following address:​certification/​aircraft/​anminfo/​finalpaper.cfm. If you do not have access to the Internet, you can obtain a copy of the policy by contacting the person listed under FOR FURTHER INFORMATION CONTACT.
