1 SCOPE

This Performance Based Specification (PBS) establishes the overall system capabilit ies, functionality, and equipage for the commercial airplane that is part of Multi-Engine Training System (METS). Section 2 identifies the Government and non-government documents cited in this PBS. Section 3 of this document establishes the mandatory capabilities of the system. Section 4 contains the criteria used to verify Section 3 requirements.

1.1 Overview

The mission of Chief of Naval Air Training (CNATRA) is to produce aviators and flight officers in sufficient quantity to support Naval Air Forces tasking. Since the late 1970’s, CNATRA has utilized a fleet of T-44 Pegasus airplanes, six cockpit training simulators, and classroom and computer-aided instruction to conduct advanced multi-engine training at NAS Corpus Christi.

Since 2007, this training has included intermediate tiltrotor training for the United States Marine Corps. Aircraft training is conducted by military instructors with simulator and academic training by both military and civilian instructors. Student naval aviators are prepared for fleet naval aviation through training in necessary skills, including, but not limited to, aircraft familiarization, radio instruments, airways navigation, visual navigation, and formation flying. The training missio ns require the METS airplane to operate in varying environmental and climatic conditions throughout the continental United States.

1.2 Application

This specification, including its appendices, represents the technical requirements for the METS airplane.

1.3 Specification Terms

This PBS contains three broad categories of requirements. The first category represents the minimum acceptable capabilities, functionality, interfaces, or environmental factors. The specification items contained in this first category are represented by “shall” statements. The second category represents desired capabilities, functionality, or interfaces that may be incorporated at the discretion of the producer. These items will be represented as “should” statements in this specification. The third category represents intent, declaration of purpose on the part of the Government. These items will be represented as “will” statements in this specification.

1.3.1 Terminology

1.3.1.1 "Shall" Requirements throughout this document, inclusive of the appendices, that are defined using "shall" statements, are considered mandatory, binding and require formal verification.

1.3.1.2 “Should" Statements using "should" express intent or desired functionality or performance above the minimum requirements.

1.3.1.3 “Will” Statements using "will" express intent, declaration of purpose on the part of the Government. In general, “will” statements express actions done on the part of the Government to evaluate the manufacturer’s compliance with the PBS.
