Avionics Design Services

Our engineering capabilities at Ascendant Engineering Solutions now include custom avionics design and certification for the entire aviation spectrum, covering the private, business, commercial, and military sectors for both fixed wing and rotary wing aircraft. We specialize in high performance designs with critical requirements for certification cost, size and power. Our expertise includes solutions for integrating a wide range of newer all-digital avionics with existing on-board analog and digital equipment, providing our customers a more cost effective upgrade path. These integration solutions are approved to design assurance levels ranging from Level A for flight critical applications to Level E for non-essential applications.

Our design team includes an on-staff systems and equipment DER and access to all other delegations. Our team takes a multi-disciplined approach to each new challenge, working with the mechanical and software teams and the DERs to optimize each system for our customer's requirements. We support all phases of certification and design, from the certification plan and PSAC through hardware design and system integration, to verification and regulatory testing and qualification, to approval. AES can deliver quick-turn prototypes or fully certified design data packages. We can also support our customer's existing designs through analysis of power/thermal management, signal integrity, parts obsolescence, reliability and conformance to environmental and EMI/EMC standards.
