2 Overview high level system testing of all FANS-1/A data link applications that includes the ability to monitor every bit of data. Capability to emulate any ATSU ATC workstation using actual ACARS network. Multiple ATC workstations to support testing of connection management and transfer of communications. extensive debug capability for real time as well as post test debugging of problems. Comprehensive test procedure linked to the ESC Generic Performance Matrices for ADS-C, CPDLC, AFN, and Data Communications. extensive information assurance capability for susceptibility testing. Slide 2

3 ACRONYMS ACARS = Aeronautical Communications and Reporting System ACTFAST = Air Traffic Control (ATC) Communications Test Facility and Avionic Systems Test ADS-C = Automatic Dependent Surveillance-Contract AFN = ATS Facilities Notification AOC = Airline Operational Communication ATSU = Air Traffic Services Unit (ATC Ground Station) CPDLC = Controller to Pilot Data Link Communications DSP = Data Link Service Provider (ARINC, SITA, et al) FANS = Future Air Navigation System FMC = Flight Management Computer MCDU = Multi-purpose Control and Display Unit PFPS = Portable Flight Planning Software VDR = VHF Digital Radio Slide 3

14 Slide 14

15 SUPPORT BEFORE THE TEST Provide FANS-1/A Expertise to Test Plans, TPWGs ACTFAST Has Developed Generic Test Scenario Helps platforms save money Helps ensure commonality among platforms Helps ensure compliance to industry requirements Assist in Efficient Testing Practices Participate in SIL test planning Participate in TIS & ground/flight test cards generation Most used uplink and downlink messages Normal operational scenarios Help to generate system level tests Technical Understanding to CWGs Help Explain Avionics/Data Link Service Provider(s)/ATSU Interactions Slide 15

16 SUPPORT DURING TEST Send Uplinks To & Receive Downlinks From Aircraft Avionics or SIL (Perform the role of ATSUs) Real Time Assessment Of Test Success Or Failure Real Time Analysis Of Decoded Messages To Determine Message Content Real Time Initial Determination Of Proper Avionics Operation Real Time Analysis To Characterize Symptoms Of The Problem Real Time Analysis To Determine Problem Source (Avionics, DSP, ATSU) Slide 16

17 SUPPORT AFTER THE TEST Provide Decoded FANS Message File In MS Word Provide Raw ATSU Data Files In Depth Analysis Of Raw/Decoded FANS Messages Detailed message content analysis Detailed symptom characterization Detailed determination of problem source (avionics, DSP, ATSU) Comparison Of ATSU Data To Avionics Data To ARINC Audit Data Timing Performance Analysis Participation in telecons to discuss and analyze problems In depth analysis of problems and assessment of industry impact Slide 17

18 LESSONS LEARNED KC-135 C-5 C-17 VC-25 89AW Slide 18

19 TESTING DETAILS Testing on several platforms that were done with vendor/prime software verification of FANS-1/A applications. Over 200 problems identified by the ACTFAST Team. ACTFAST worked with vendor/prime to resolve many problems and was used to proactively reduce future problems. As programs return to ACTFAST for program updates, ACTFAST becomes more critical to that program. Slide 19

20 LESSONS LEARNED (continued) Determine Problem Reporting Mechanism Up Front Test to Industry Requirements, Not Necessarily Platform Requirements Explain why tests are to industry requirements and help understand differences Allows necessary changes to be made early in program The Earlier Full System Level Tests Can Be Performed, The Better System Level Tests Should Represent Normal Operational Actions Fly VFR As Much As Possible When Testing Data Link Operation FMS Should Be Flying Aircraft For Proper Data Generation Slide 20

21 LESSONS LEARNED (continued) When Flying, Have Aircrew Perform Data Link Operations Have Aircraft Load And Follow Data Link Clearances DSP Connectivity Problems Can Abort Test Tail Number not in System (run Connectivity Tests for all new aircraft) SITA vs ARINC AOC Message Labels not in correct ARINC Table Test with DAFIF Navigation Data Base As Soon As Possible Major Differences Between Jepessen and DAFIF/AWE Allow Time Between Tests For Timely Analysis of Results Avionics State Data Required For Analysis of Problems Slide 21

22 LESSONS LEARNED (continued) Static Testing Not Sufficient (SIL Fidelity) Test Various Transfer Of Communication Scenarios Test Multiple ADS Connections Often HFDL Performance Use HFDL as little as possible, but as much as necessary Slide 22

23 LESSONS LEARNED ISEs Need ISE In Area Of Operations Ensure Connectivity Prior To ISE Ensure TACC Is Involved To Support Test Have DSO Personnel At ATSUs Do Not Test Data Link On FIR Boundaries Hold Meetings With ATSU Personnel Before And After Test Tell them in advance what tests are planned and when Get their post-test comments in writing (even if everything went well) Slide 23
