1.0 Background

Armstrong Flight Research Center (AFRC) operates a F-15D, tail number N884NA. This particular aircraft is equipped with a standard F-15 radar which can detect and track aircraft and small high-speed targets at distances beyond visual range down to close range, and at altitudes down to treetop level. In the event the radar becomes un-operational, NASA has provisioned an alternative which may be implemented to provide similar functionality to the radar.

According to the NASA Procedural Requirement document Aircraft Operations Management NPR 7900.3 paragraph 3.3.1:

“All manned NASA aircraft shall be configured with FAA-approved Traffic Alert and Collision Avoidance System (TCAS) and Terrain Awareness and Warning System (TAWS) for the specific type model aircraft to mitigate midair collisions and controlled flight into terrain. Alternative FAA-approved systems such as ADS-B in/out or other FAA-approved emerging technologies are also acceptable.”

The NASA Armstrong Instrumentation group developed a design for a Honeywell/Bendix King CAS 66A TCAS I and Sandel ST3400 TAWS units for integration into the F-15D to address the above requirement. During the design review of the integration drawing, one of the reviewing engineers noticed a possible issue with the blanking/suppression connection between the existing aircraft systems and the new TCAS I and TAWS units. The team investigated the possible issue, and determined that this connection requires additional investigation with the assistance of TCAS experts. The F-15 Instrumentation team is reaching out to industry experts which are intimately familiar with the this Honeywell TCAS I system and can design the integration of the unit into an F-15D.

2.0 Objectives

There are two primary objectives:

• Provide a recommended design to the NASA Armstrong F-15 team that will properly integrate the existing NASA owned equipment into the into the current F15D avionics systems. NASA current equipment list:

o TCAS I Honeywell/Bendix King CAS 66A o TAWS Sandel ST3400 o Bendix King TCAS Antenna

• The existing aircraft systems shall continue to operate as a result of the TCAS/TAWS installation.

• Provide technical troubleshooting assistance after completion of the installation to ensure the system is operational.

3.0 Scope

The NASA 884 aircraft will have an operational TCAS I/TAWS system that can interrogate the ATC transponders of other aircraft in flight. It is expected the TCAS I will then process this information and display the positions of surrounding aircraft to the pilot.

4.0 Requirements

The contractor shall provide the following:

• Analyze current NASA preliminary design of the TCAS I/TAWS and antennas.

• Travel to NASA Armstrong Flight Research Center to review existing F-15D documentation necessary to design TCAS I/TAWS installation.

• Provide a design for the TCAS I/TAWS installation.

• Provide operational checkout and troubleshooting expertise upon completion of TCAS

I/TAWS installation into the F-15D.

NASA shall provide the following:

• Provide access to NASA preliminary TCAS I/TAWS wiring diagram and documentation upon contract award.

• Provide all NASA TCAS I/TAWS system component model and part numbers.

(Example, antenna, display etc. model and part numbers).

• Provide all CAS 66A and ST3400-102 installation manuals, maintenance manuals and pilots guides.

• Provide necessary information from F-15 wiring diagrams that contain information to accomplish the design, contractor may have to travel to Armstrong Flight Research Center (AFRC).

o F-15D documentation may only be viewed on sight at AFRC.

• Be available to respond to questions about aircraft and project details.

• Provide all parts and components to install the design.

• Install the NASA provided CAS 66A (and any associated components identified in the design) into the F-15D per contractor design.

• Support checkout and troubleshooting in coordination with NASA avionics personnel of the TCAS I/TAWS installation on NASA F-15D aircraft.

5.0 Deliverables

The contractor shall deliver the following:

• Provide feasibility study of installing the CAS-66A on the F-15D based on information provided by NASA. If the contractor determines that the CAS-66 system can't be integrated into the F-15D with the units NASA has on hand, the contractor will suggest alternative units.

• Provide TCAS CAS 66A design drawings and any associated recommendations for installation into the F-15D within 45 days of contract award.

• Design review within 60 days of contract award.

o Desire is for the Design Review to by completed by the end of fiscal year 2019

6.0 Period of Performance

The period of performance will be through FY2020. It is expected the design would be completed in FY2019 and the installation support would be accomplished in FY2020.

7.0 Travel

Contractor travel to NASA Armstrong Flight Research Center is authorized.

It is expected the contractor will make a minimum of five trips:

• To meet the F-15D crew and look at the airplane

• To access F-15D documentation

• To provide a final design review

• To provide expertise during operational checkout and troubleshooting activities

Each trip will be individually invoiced after travel is completed with the expectation it will be paid shortly thereafter.
