ARP-4761 Training, Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment

ARP-4761 Training Course Description

ARP-4761 training provides you with the strategies and techniques to execute safety analysis. Such strategy is relevant with demonstrating compliance with certification criteria (14CFR/CS Parts 23 and 25, section 1309) and helping an organization to fulfill their own unique safety guidelines. The safety procedures explained are mainly relevant with civil avionic gear but the procedures and techniques might be used in several cases.

ARP-4761 training covers the standard data to perform the industry approved safety analysis including Functional Hazard Assessment (FHA), Preliminary System Safety Assessment (PSSA), and System Safety Assessment (SSA). We will discuss different safety evaluation techniques required to implement and perform the safety analysis. We also will teach you various safety evaluation techniques consisting of Fault Tree Analysis (FTA), Dependence Diagram (DD), Markov Analysis (MA), Failure Modes and Effect Analysis (FMEA) and Common Cause Analysis (CCA). CCA is comprised of Zonal Safety Analysis (ZSA), Particular Risks Analysis (PRA), and Common Mode Analysis (CMA).

ARP-4761 training

ARP-4761 training teaches you the Safety Assessment Process in avionic systems, as well as incorporating it with other execution procedures. We will discuss the essence of the Reliability Theory and its relevance to airborne systems, equipment specifications and that how they are applied during both the initial and final system safety assessment process.

ARP-4761 training course also considers each of the tools and techniques for performing the Safety Assessment Process, containing real-world scenarios for each of the fundamental methods. We will elaborate precisely how the regulatory structure works and how ARP-4761 fits in. We also explain how ARP-4761 corresponds to other standards for civil airborne systems and equipment, in particular with ARP-4754A.

ARP-4761 training course is mostly dedicated to the practical activities including labs, individual/group activities, and hands-on workshops.

TONEX Workshop Sample: The Wheel Brake System

The Wheel Brake System is installed on the two primary landing tools. Braking on the major apparatus wheels is applied to give support to safe impedance of the airplane during the taxi and landing phases, and also in the case of a rejected take-off. A secondary role of the wheel brake system is to stop the main gear wheel rotation upon gear withdrawal.

Such braking system can be conducted both commanded manually, via brake pedals, or automatically (auto-brake) with no need for pedal use. The auto-brake operation helps the pilot to pre-equip the braking rate before takeoff or landing. When the wheels have traction, the auto-brake operation will regulate the pressure necessary for brake to smooth the deceleration.

Based on the ARP-4761 guideline, discuss:

  • Nominal system modeling
    • Braking System Control Unit (BSCU)
    • Hydraulic pressure pumps
