1.0 Introduction

The 93rd BS, 307th Bomb Wing, Barksdale AFB, LA requires a multichannel audio/video mission data recorder to effectively accomplish their B-52 Flying Training Unit (FTU) mission. This B-52 recorder will be installed as a T-1 modification on 93rd BS B-52s. The recorded data will be captured in a way that allows the crew to easily replay a mission and review their instrument readings, aircraft position, weapons employment, radio communications, etc.

1.1 Purpose

The purpose of this TRD is to describe the B-52 recorder hereinafter called DBRIEFR. The DEBRIEFR will consist of a mission data recorder, Removable Memory Module (RMM), and a Crash Survivable Memory Unit (CSMU) required to meet functional and technical requirements to support the acquisition of a reliable solid state recording system to satisfy the 93rd’ Wing .

1.2 Scope

This TRD establishes requirements for performance, development, and test of a DEBRIEFR, RMM, and CSMU. The terms “threshold” and “objective” are in bold type, followed immediately by the stated requirement. Threshold requirements are the minimum required to be provided. Objective requirements are defined as the ultimate goal, and depend on technology advancements.

Additional information (sometimes stated in directive terms) is considered amplifying data.

The term “Shall” is used to dictate the provision of a functional capability; to denote something that is required.

The term “Will” is used as a statement of fact; to cite items that the operational environment is to provide to the capability being specified.
