LTN-92 Nav Data Base

[four engine jock]

Please if anyone can help.
We just installed a LTN-92 INS system in one of our aircraft and need to purchase the NAVIGATION DATA BASE.
Can anyone help on this?
Regards

Have you tried Jeppesen?

Yes tried them and no joy

I would suggest going back to Northrop Grumman and see if they are still supporting the LTN-92 and said database? Might be a better starting point perhaps?

:ok:

Thanks. Busy with that now .
Northrop Grumman not easy to deal with.

We operated for years without a database in the Litton 92.

LTN support only OEM's database. I am also facing problem in loading of data. My old data of 90's went croupt. I got new data of 2016 but its not being loaded. diagnoses still on.

I think its better for me to use old data and than customize it. I have other INUs with data loaded, i have tried crossfill which does not work.
any one know how to retrieve data from INU into external floppy?
