I was wondering as to the measurements of "black box" recorders. I have a new invention involving the "Black Box" and I need to know the measurements of the recorder.

  • $\begingroup$ you are wondering what, exactly? what quantities are measured? how often? why are recorded? $\endgroup$ – Federico Aug 1 '14 at 22:00

    $\begingroup$ Please clarify what you are asking. Are you asking what the physical dimensions are? Are you asking what data they record? Something else? Do you have specific recorders in mind? FDR vs CVR? $\endgroup$ – Bret Copeland Aug 1 '14 at 22:07
  • $\begingroup$ google ARINC429 to learn about the data bus aircraft use, and then read up on the ARINC standards defining what goes over the bus, then just record everything you see. Good luck! $\endgroup$ – casey Aug 1 '14 at 22:41

The two main "black boxes" are the Flight Data Recorder (FDR) and the Cockpit Voice Recorder (CVR). These units are available from various manufacturers and therefore sizes vary. Many units can be used as either CVR or FDR, or as both.

A quick search provides a few examples:

etep Sentinel ED-112: CVR/FDR
Height: 3.929 in (9.980 cm)
Width: 4.970 in (12.624 cm)
Depth: 6.907 in (17.545 cm)

L3 F1000: FDR
Height: 7.62 in (19.4 cm) Width: 4.88 in (12.4 cm) Depth: 19.56 in (49.7 cm)

Universal Avionics Systems CVFDR: CVR/FDR
Height 6.1 in (15.5 cm)
Width 4.9 in (12.4 cm)
Depth 8.0 in (20.3 cm)

standard configuration:
Height: 3.25 in (8.26 cm)
Width 5.55 in (14.1 cm)
Depth: 6.55 in (16.6 cm)
extended configuration:
Height: 3.25 in (8.26 cm)
Width: 5.55 in (14.1 cm)
Depth: 7.2 in (18.3 cm)

L3 FA2100: CVR
Height 5.5 in. (14.00 cm)
Width 5.0 in. (12.70 cm)
Depth 12.6 in. (32.00 cm)
