F-15 Avionics System Integration
and Test Laboratory
Our technicians extensively test new radar Operational Flight Programs
(OFPs) using the APG-70 Radar Test Bench (RTB). The APG-70 RTB interfaces
with the F-15E tactical avionic systems including the Central Computer,
Inertial Navigation System (INS), Crew Station Controls and Displays and
Interrogator Reply Evaluator (IRE). We conduct postflight RTB tests for
analysis of anomalies from flight tests. We also accomplish radar OFP ground
testing using various methods to simulate targets.
Interactive Data Reduction and Analysis System (IDRAS):
We use the IDRAS for the reduction and analysis of APG-70 radar flight
test data. Upon completion of an F-15E radar flight test, we transfer the
onboard 28-track magnetic tape with flight test data from the aircraft
to the F-15 IFAST bay. Our technicians reduce the 28-track data are to
9-track format. They normally accomplish extensive analysis on the test
data. Additionally, they also use IDRAS to collect test data from APG-70
radar testing accomplished at IFAST.
F-15 Avionics Integration Support:
The F-15 has a total of 7 software controlled avionic systems. These include
the Central Computer, Multipurpose Display Processor, Avionics Interface
Unit, Radar, INS, Programmable Armament Control System and Flight Control
System. We operate or simulate ninety percent of the F-15E avionics in
the F-15 IFAST test bay. Our technicians periodically develop new software
reflecting system improvements and release it for flight test and subsequent
installation in the operational fleet. The technicians verify any hardware
or software discrepancy detected in any flight test on the integrated avionics
test benches in IFAST. Subsequent fixes are verified prior to reflights.
The integrated avionics test benches also provide a valuable training tool
for pilots, weapon system operators and engineers; particularly for new
OFPs.
Avionics Intermediate Shop (AIS):
AIS capability utilizes the F-15E avionics test benches, which affords
a "hot mock-up" environment. Avionics engineers install suspected
defective LRUs on the test benches and monitor their operation. They conduct
fault isolation to an internal board level using traditional troubleshooting
techniques. We return any LRUs identified as defective to the appropriate
AF shop for disposition. We return serviceable LRUs to the CTF for aircraft
installation. The AIS test benches provide software reload capability for
all of the microprocessor driven avionic systems in F-15 aircraft.
ECM Pod Preflight Testing:
The F-15 fire control radar is designed to be effective in an ECM environment.
The dynamic nature of ECM combined with new tactical radar modes necessitates
software changes to the ECCM capabilities of the radar. Our technicians
use the ECM pods mounted on support aircraft to exercise the ECCM capabilities
of the F-15 radar during flight tests. We accomplish pre-takeoff testing
of ECM pods on support aircraft from IFAST to ensure optimum results during
flight.

B-lB Offensive Avionics Laboratory
(OAL)
The Vehicle System Simulator (VSS) emulates the air vehicle systems
as required to operate the offensive avionics through a simulated flight
profile. The crew member can execute and pre-fly test procedures in the
OAL environment prior to flight tests. The Weapons System Simulator (WSS)
emulates the weapons intended for use on the B-lB. We use one channel of
the offensive radar system to operate and test in the OAL. Using available
facilities in IFAST, we accomplish ground testing of the B-lB radar. Additionally,
a Radar System Simulator (RSS) provides capability for the aircrew to interact
with the radar set. The B-lB defensive avionic system and OAS are integrated;
however, we can operate each independently. The OAS contains crew station
controls and displays for both offensive and defensive avionic systems.
Radio frequency (RF) management between the two systems is an important
integration requirement evaluated in IFAST.
The Integrated Test Station (ITS) provides the capability to integrate
weapons with core avionics. Technicians perform weapons integration testing
prior to aircraft installation. This may be the first occasion for a weapon
to be fully integrated and tested with B-lB core avionics. The ITS provides
a means for replication and investigation of anomalies experienced during
flight. Our technicians use the ITS to investigate hardware and software
anomalies and record activities on a variety of data recording systems
to facilitate real-time data analysis as well as post-test analysis.
The Test Mission Data Preparation System (TMDPS) is in the B-lB IFAST
test bay. It provides the capability to produce mission data and avionics
flight software data transfer unit cartridges (DTUCs). Technicians generate
mission data DTUCs prior to flight. The DTUCs contain flight profiles,
sequence or way points and target information. They also store information
required by the Avionics Flight Software (AFS). The dynamic requirements
of flight test often demand short-notice changes to the planned test flight.
The OAL supports software changes on-site due to the flexible capability
of the DTUCs. We also use DTUCs during aircrew training by providing point-to-point
simulation runs of the planned test profile. Technicians subsequently install
a DTUC on the B-1B aircraft for test flights. AFS DTUCs are built from
9-track tapes in support of the test program. The TMDPS provides on-site
capability to produce AFS and mission data DTUCs to support test flights
and crew training. The B-lB OAL possesses test sets required to bench test
all avionic LRUs. Additionally, we accomplish LRU modifications and intermediate
level maintenance in the B-lB IFAST test bay.
B-lB Defensive System Laboratory
The B-lB Defensive Systems Laboratory consists of the following:
a single sector and core avionics of the defensive avionic system as installed
on the B-lB aircraft, LRU STE stations, dynamic signal generator, engineering
work stations and VAX computers for data reduction, data analysis and real-time
analysis of the defensive avionic system. Systems integration capability
provides a unique test environment in which to test the B-lB Defensive
Management System.
In addition to the engineering staff, the defensive avionic systems
test station, the LRU specialized test equipment (STE) and standard lab
equipment, the defensive laboratory has the following resources:
- VAX 8530 & 11/750 computers with MIL-STD-1553
data bus interface
- Digital MIL-STD-1553 data bus recording
and simulation
- Multiple SBA-100 MIL-STD-1553 data bus
analyzers
- Video monitors and recorders with full
editing capability.

to simulation via shared memory.
-- Models consist
of separate input/output (I/O), decision and computational sections to
allow for reconfigurability of modeled avionics with real avionic hardware
and software.
- Data Collection.
