Solid state memory for aircraft flight data recorder systems

摘要: A memory unit for a aircraft flight data recorder system uses an electronically erasable solid state storing the and controller circuit are housed in penetration resistant, thermally insulated enclosure. Power dissipation within enclosure is minimized by external switching that applies operating potential to only when being transferred from circuit. protection circuit, located inhibits write erase operations whenever falls below predetermined level. In continuously data, oldest stored overwritten with newly arriving maintains erased boundary defines beginning end of recorded data. power monitor outside enclosure, resets following interruption. dedicated portion space utilized store address faulty locations (detected during storage sequence) stores ending selected portions record. The sequenced skip both associated record new stored.
