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 racks/cabinets 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.
