RAW FDR DATA

To give one an idea of RAW data:

1 word = 12 bits (Harvard BiPhase Code)
  • not all bits used for value, some words contains only discretes, a combination of value and discrete is also possible (depends on attached computer/equipment)
1 subframe contains 256 or 512 words.

1 frame consists out of 4 subframes (= 4 sec. of data)
  • not all frames are used identical, e.g. the sample rate for acceleration may be once a second while documentary type may be sampled once every 4th second.
1300 parameters (330 mandatory) are recorded for 25 hrs.
