SAE ARP4104-2007 PDF

Full title and description

SAE ARP4104 — Design Objectives for Handling Qualities of Transport Aircraft. This SAE Recommended Practice defines design objectives and guidance for the handling qualities of transport-category fixed-wing aircraft (subsonic, transonic and supersonic regimes), and includes an associated annex (ARP4104/1) addressing flight‑envelope awareness and protection features.

Abstract

Specifies requirements and design objectives for handling qualities applicable to transport aircraft. The document provides both quantitative and qualitative guidance intended for aircraft handling‑qualities design, evaluation, flight test and simulation, and human‑factors considerations. It excludes most rotorcraft/VTOL‑specific objectives and includes an annex for flight‑envelope awareness/protection.

Scope

Provides requirements and design objectives for the handling qualities of transport aircraft operating across subsonic, transonic and supersonic speed ranges. The objectives are intended for fixed‑wing transport aircraft and are not necessarily applicable to rotorcraft or VTOL types. The annex ARP4104/1 gives supplemental objectives when control laws or characteristics are modified for envelope awareness/protection.

Key topics and requirements

• Design objectives for handling qualities (pitch, roll, and yaw response and mission‑relevant metrics).
• Quantitative and qualitative criteria for pilot ratings and evaluation.
• Guidance for flight test and simulation evaluation of handling qualities.
• Human‑factors and flight‑deck implications for control and displays related to handling.
• Flight‑envelope awareness and protection design objectives (detailed in ARP4104/1).
• Application notes on control law modifications, pilot‑vehicle interface, and system‑level considerations.

Typical use and users

Used by aircraft OEMs, flight‑control system designers, flight‑test engineers, simulation engineers, avionics and flight‑deck suppliers, human‑factors specialists, certification authorities and airlines engaged in handling‑qualities assessment, design verification and compliance activities. The guidance is commonly referenced during design reviews, flight‑test plans and handling‑qualities assessments.

Related standards

Includes the annex ARP4104/1 (Flight Envelope Awareness/Protection). Historical lineage shows ARP4104 replaces or updates earlier ARP documents (for example ARP 842B is listed in document history). Users often cross‑reference other SAE ARPs and applicable civil‑aviation certification guidance for handling‑qualities and flight‑control design.
