B757 DFDAU

[NW3]

Hello.

Just wondering if anyone knew if there was a list of the available parameters for inclusion in the B757 DFDAU (touchscreen interface to the flight data recorder - I'm sure it may be installed in other fleets / types etc.).

Our SOP requires us to select GW, FCOM, FTME, and FM, but I've also seen people pull things like AGDL, LATG, STAT etc. out of the bag.

Thanks

FDR parameters are mandatory (CFR 14 Part 121 Appendix Mhttp://ecfr.gpoaccess.gov/cgi/t/text....19.26.11.5.58) so are you in fact just selecting items for the Quick Access Recorder as part of your airline's Flight Operations Quality Assurance or maintenance program? All the "optional" items you quoted are all mandatory AFAIK. The DFDAU drives both the FDR and QAR.

That's all the ones for our 757's with the DMEP fitted. I didn't have time to format my cut 'n' paste so you'll have to look for the codes within the text.
The columns are Parameter Name, Mnmonic, Source.
I'll come back later and tidy it up to make it clearer for you but from the last on the list you can see that it's Body Yaw Rate , the code is YAWR and it comes from the IRS.

Cheers, Fargoo

p.s. As a small disclaimer, these are for one specific airline setup and may not all work on your 757 (most should though).

I see that's the list for the DMEP - I think our 757s have an IDU installed (touchscreen panel as opposed to physical buttons), and I see from the list above things like AGDL, FM don't appear... I'll have a bash but guess there might be a different list somewhere.

Thanks for the info though Fargoo, and ICTSLB - sorry I think I didn't write my question that clearly. As you rightly say it's not really the parameters that the FDR itself is recording - this is just an interactive display to the pilots of a number of available parameters.

Sorry, I should of RTFQ!
Can't access codes list for the DFDAU you have 'cause our fleet doesn't have it fitted.
