SOLID STATE FLIGHT DATA RECORDER
4X SPECIFICATIONS
Honeywell Part Number 980-4700-04X
Packaging ARINC 404, 1/2 ATR Short & Long
Weight 16 or 18 Pounds, Nominal
Power 115 VAC, 400 Hz, 15 W; 28 VDC, 8 W
Data Capacity 25 Hours @ 256 Words/Sec (3,072 bits / Sec)
50 Hours @ 128 Words/Sec (1,536 bits / Sec)
100 Hours @ 64 Words/Sec (768 bits / Sec)

The SSFDR's crash survivable memory unit (CSMU) provides for complete data recovery when subjected
to the crash conditions stipulated in ED-55 and ED-56a:
• Impact Shock 3400G, 6.5 milliseconds
• Penetration Resistance 500 lb. weight from 10 feet
• Static Crush 5000 lbs., 5 minutes
• High Temperature Fire 1100°C, 30 minutes
• Low Temperature Fire 260°C, 10 hours (per ED-56a)
• Deep Sea Pressure and 20,000 feet, 30 days
• Sea Water/Fluids Immersion Per ED-55
The CSMU design has been fully qualified to these requirements and, in fact, exceeds them by
considerable margin in key survival areas:
• Impact shock has been successfully demonstrated at 4800 G's
• High temperature fire exposure has been tested to 60 minutes
• Low temperature fire was tested immediately after exposure to 1100°C fire
