TF01

Tech: Ivana; MC: Julie; Scientists: Sarah, Chris, Biff; Pilots: Brent, Bo

-Per Sarah's request, used "CDP PBP (only used if swoods asked)" xml instead of Default xml

-N2 Window Purge turned on at 1845

-Approximately 1hr after power start, noticed Right side Primary Inverter (B1) Fault light. Used meter to check that 115V 60Hz power was still being delivered to power outlets. Carrying on with flight without power restart.

-Scattered light from Biff's laser was affecting pilots' night vision, so used felt piece to cover inboard side of L-1 rack. On maintenance day, make another curtain using black foam material.

-Chris pointed out that AKRD (angle of attack) didn't look right - AKRD is derived by ADIFR and other coefficients. Could be due to formula change with this xml, or due to moisture in lines. On maintenance day, check with SE's about xml and visually inspect radome lines for moisture.

-2DS: Per Sarah's instructions, keep H Tx/Rx Arms and V Tx/Rx Arms OFF. Heaters coming on and off not good for laser alignment, and conditions for CGWaveS project should not require them to be turned on at all. On maintenance day, update 2DS Checklist.

-Before shutting down aircraft power, tried power cycling Mission Power and Right Bus. Fault light on B1 still illuminated.

    Regarding AKRD and ADIFR: We inspected the radome lines for moisture during maintenance day on 5/8/25 and found water in QCR and ADIFR lines. Photo attached (ADIFR line is marked with red tape - water is to the left of the T-fitting).
