About ARP4754A (Civil Aircraft Development)

This training provides practical skills and structured learning on the compliance requirements covered by ARP4754A.

ARP4754A (ED-79A) governs development of civil aircraft and systems: requirements capture, allocation, and validation/verification at aircraft and system level, orchestrating where DO-178C/DO-254 items get their DALs and requirements.

What it regulates

Development assurance planning, requirements validation, FDAL/IDAL assignment from safety analyses, integration verification, and configuration/change management across the aircraft hierarchy.

Who must comply

Aircraft OEMs and system integrators (flight controls, avionics suites, propulsion control).

Key requirements of ARP4754A

  • Aircraft/system/item hierarchy with requirement flow-down
  • FDAL/IDAL assignment logic with independence credit
  • Requirements validation (right requirements) vs implementation verification
  • Coupling to ARP4761 safety assessment throughout

Key concepts: ARP4754A

Development vs safety process
4754A (development) and 4761 (safety assessment) run as interlocked twins.
FDAL/IDAL
Function and item development assurance levels allocated from failure-condition severity, with architecture-based reduction rules.
Requirements validation
Structured demonstration that stated requirements are correct and complete before proving compliance to them.

Frequently asked questions: ARP4754A

Why is DAL assigned at system level and not chosen by suppliers?

Assurance levels derive from aircraft-level failure condition severity through the 4754A/4761 process; suppliers inherit FDAL/IDAL with the architecture rationale, not commercial preference.
