1 SCOPE

This Performance Based Specification (PBS) establishes the overall system capabilities, 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 1980, 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 missions 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 two 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 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 “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.

4 Verification Section 4 specifies the initial Government recommendations for verification of requirements delineated in Section 3 of this PBS.

The following verification methods are used in this section:

- Inspection (I) - examination of documents, certificates of compliance, report, or hardware.

No testing conducted.

- Analysis (A) - technical evaluation of data, analysis, or reports not based on testing to determine compliance with requirements.

- Demonstration (D) - the exercise of hardware, software, and/or operations to determine by observation, with no specific instrumentation or data collection that qualitatively specified functions can be performed. These requirements will be verified during a System Performance Demonstration (SPD) or Government Acceptance Test (GAT).

- Simulation (S) - the use of established technical or mathematical/computer models, algorithms, charts, graphs, circuit diagrams, or other scientific principles and procedures to provide evidence that stated requirements are met.

- Test (T) - the exercise of hardware, software, and/or operations using procedures and instrumentation/measuring equipment to verify compliance with quantitatively specified requirements. Specific instrumentation or data collection is required and post-test analysis is performed.

- Non-Verifiable (NV) - not a requirement that can be verified (e.g., a definition).

Appendix A

Appendix A: Definitions, Abbreviations, And Acronyms Glossary The glossary is a collection of the definitions used to help bound and clarify the requirements. The words and terms defined here appear in context in the main body and appendices of this specification.

Airspeed --Calibrated Airspeed (CAS) is basic airspeed corrected for pitot-static error and (or) attitude of the aircraft

--Indicated Airspeed (IAS) is the uncorrected reading taken from the face of the indicator.

--True Airspeed (TAS) is equivalent airspeed that has been corrected for air density.

Capture -- Capture is defined as automatically transitioning to a flight parameter at a selected reference value that is to be held.

Caution -- A cautionary condition is defined as a condition in which some hazard exists if flight or aircraft/system operation is unduly prolonged. It requires the aircrew's attention and response.

Electrical System -- The electrical system includes all components required for generation, storage, conversion, regulation, distribution, and control of electrical power. It also includes bonding and electrical system protection.

Endurance --Time to fly a zero wind, Appendix B profiles from takeoff to destination at MTGW arriving over destination with reserve fuel

Environmental Conditions -- Operational day is temperature 95ºF (35ºC) at 3,000 feet pressure altitude.

-- Standard Day is temperature 59ºF (15ºC) at 0 feet pressure altitude.

Failure -- An event in which a system, subsystem, or component does not perform as specified.

Fuel -- Fuel is considered in the following categories:

Endurance Fuel --Fuel required to fly a zero wind Appendix B profiles from takeoff to destination at MTGW in operational day conditions.

Reserve Fuel --10% of initial mission fuel, or 20 minutes at max endurance airspeed, or original equipment manufacturer flight manual reserves, whichever is greater.

Mission Fuel --Fuel required to complete Appendix B profiles.

Page | 24

Internal Fuel -- Fuel that is contained in permanently installed tanks enclosed by and secured to the normal structure and panels.

Usable Fuel -- Internal fuel less unusable fuel.

Unusable Fuel -- Total fuel that is unavailable to the engine under normal level flight and landing conditions.

Primary Fuel -- A fuel that the aircraft is authorized to use for continuous unrestricted operations.

Hazardous Condition -- A hazardous condition is defined as a condition in which some danger exists if flight or aircraft/system operation is unduly prolonged. It requires the aircrew's immediate attention and action.

Independent -- Design feature that provides a primary and a secondary means for sustaining system operations in the event of equipment, circuit, or system outages. The secondary implementation is not required to be an exact hardware or software duplication, but it does provide the same functionality and capabilities.

Pressure Altitude (PA) -- Pressure altitude is the altitude reading with the altimeter set to 29.92 inches Hg.

Redundant -- Design feature that provides a primary and a secondary means for sustaining system operations in the event of equipment, circuit, or system outages. The secondary implementation is required to be an exact hardware or software duplication and provides the same functionality and capabilities.

Service Ceiling -- Service ceiling is defined as the altitude at which the maximum steady-state rate-of-climb potential is 100 ft per minute for a specified configuration, weight, speed, and thrust (power) setting.

Warning -- Warning is defined as an indication of the existence of hazardous conditions that require immediate corrective action. A warning is displayed in red, accompanied by an audio message and both are attention getting.

Weight:

Basic Weight -- The basic weight is the weight of the airplane with the following assumptions:

-- Basic Weight includes all systems that are required to allow the airplane to meet all the requirements of this specification, installed and ready for operational use,…
