High-Speed Quick Access Flight Data Recorder
SkyLog-QAR
VERSATILITY
The quick access recorder (QAR) is an extremely small LRU able to acquire, process and store data from multiple sources in a readily accessible location.
The QAR automatically records two independent storage mediums, a removable SD/SDHC memory card (up to 256 gigabytes), as well as an internal 4 gigabyte NAND SLC grade memory chip.
Data retrieval is through either removal of the SD card or an internal 4G LTE Cellular modem which can automatically upload recorded data to the cloud on aircraft touch down. The cellular module supports global frequency bands and incorporates an internal MIMO antenna array with no need for external antennas.
An optional weight-on-wheels signal prevents any RF transmission via hardware interlocks to prevent transmission in flight where applicable due to regional NAA requirement. To address cyber security considerations the QAR incorporates both high strength RSA 2048 bit and AES 256 bit encryption, supported with a TPM 2.0 security device. The QAR can also function as a ethernet to secure cellular communication bridge.
