Discussed flt-ops for optical bench & LN2 (pilots, mechs, techs) with users - further discussion needed
Jenna declined N2 window purge
Takeoff 1638
Fwd camera inop - no cameras found, driver issue suspected
VXL2 is not working
1655 QCR iced-up?
Turned on N2 purge after tiny ice particles were noticed between the window panes at 47Kft (on both the top and the side window). It did help to clear the ice somewhat, need to start N2 purge at the beginning of pre-flight on flt days. The Mott frit on the N2 delivers 500 sccm at 30 psi, this is then teed to both windows via 1/8" od teflon tubing, or 250 sccm to each window. The N2 cylinder has about 900 psi remaining.
TCAB may be reading higher than actual ambient cabin temp, maybe by +5 deg C, just a guess by me
