Here is my analysis of the specific requirements for DFDR Channel count requirements for
F900B S/N 051, Type certA46EU, originally issued March 7, 1979:
ICAO Annex 5 Part I, chapter 6
After reviewing every exciting paragraph carefully, we are NOT required to have a Type I, Type IA, Type II, OR a TYPE IIA recorder. These types of recorders have concisely defined lists of required parameters.
The paragraph that we are forced to comply is 188.8.131.52.9, and 184.108.40.206.10, including a), and b).
These requirements are VERY VAGUE and obviously meant to be looser requirements than the Type 1and type 2 recorder installations.
How do we comply?
DFDR P/N 980-4700-25 in BMB and BZZ:
We can now use the HHDLU owned by Duncan BTL. Contact Scott Davis at FTW to rent it.
Send the results of the download to
Also send this list:
then fight through the results to see if anything is REALLY missing? File the results.

OTAR 91.140 (a) (1) (ii)
Now then…. here is the history that was set in motion by the insistence of Dan Staina.
The items that we have been complying with up to this point are:
ICAO Annex 6 , Appendix 8, Section 7.
7.1 is complied by the Pilot’s Taxi Checklist.
we got that sorted out 2 years ago with a Notice To Staff.
7.2 a), and b) is complied by pulling the DFDR and sending it to Honeywell…..GIGANTIC pain in the behind. Honeywell provides a letter that states the DFDR is correctly recording the parameters that the Falcon work card calls for. (32 parameter list)
c) is complied by having the pilots pull the C/B on the Taxi In prior to the removal.. That way we capture a full flight for Honeywell Analysis.
e) The Falcon work cards fully test the CVR operation in the airplane.
f) “where practical” The CVR’s are removed and read out every year. The CVR from BZZ goes to Duncan for readout. Honeywell for the other CVR’s. We retain a voice CD of the recordings. I was been verifying the “Intelligibility” myself by listening to the .WAV file.
I say that is SUPREMELY UNPRACTICAL. I would like to suggest that you quit doing this and change the CAMP code to AS REQUIRED
g) N/A , none of the aircraft are fit with AIR (Video Recording)
7.4 we comply with this by filing the Honeywell and Duncan results right in the work order binder.
7.5 a) this is due on BMB. It is not due on BZZ because it has been installed less than 5 years. Best I can tell, this is ONLY the calibration of the 3 resistors that report the control column position.
This is the best summary of where we stood 6 months or so ago.
