BAROMETRIC ALTIMETER DIGITAL REPLACEMENT

Request for Information (RFI)

Barometric Altimeter Digital Replacement

RFI Number: N00421-30-RFPREQ-TPM209-0001

Classification Code (PSC): 6605

NAICS Code: 334511

1. THIS IS A REQUEST FOR INFORMATION (RFI) ONLY. THERE IS NO SOLICITATION PACKAGE AVAILABLE. The Naval Air Warfare Center Aircraft Division (NAWCAD), Patuxent River, MD, is soliciting information from industry to determine market capability of sources regarding the availability and technical capabilities of digital barometric altimeters to replace existing analog or legacy systems.
2. The United States Navy currently utilizes analog/mechanical barometric altimeters across a variety of platforms (e.g., aircraft, UAVs, ground stations). These legacy systems are increasingly difficult to maintain due to obsolescence, limited parts availability, high maintenance man-hour costs, and performance limitations. The Navy is seeking to replace the AAU-32, AAU-39, and AAU-52 barometric altimeters that are form/fit/function compatible or adaptable to legacy systems, can provide enhanced performance, accuracy and reliability, and meet aviation or mission-specific regulatory and environmental standards.
