Purpose of Flight:Check
Comments:The EMI/EMC checks were completed with no new items noted. The interference on VHF1 freq 125.0 (KLFI Tower) was still present same as last year, workaround successful using UHF. The HF radio was not checked as it was inop. The ICF was flown in marginal cloud conditions and due to mid-high level clouds we never reached FL300 as intended, but enough opportunity existed for the ACES system to check functionality. Conversation within the aircraft during the flight indicated ACES was not performing nominally but the in-situ system was working fine. Most data was taken around 10,000’ with one spiral down to 100’ AGL over water. Post flight data review suspected the new optics that were added from last year may have been interfering with the laser performance.
