Cockpit Voice Recorder - Underwater Beacon
FYI :
I just read this on the CVR transcript from USAIRWAYS 1549 public hearing that was released today 06-09-09.
The CVR had no apparent external damage, other than being wet. The
underwater locator beacon (ULB Dukane Model DK100, s/n DM1661, battery expiration
date October, 2009) did not function when tested. After shorting the center electrode to
the case, no sound was detected using a Dukane Ultrasonic Test Set Model 42A12.
The beacon was also tested using a Dukane Test Set Model TS100, which indicated
“Open Probe/Batt.”
Figure 3
I hope they find the CVR for AF 447
