4.3.6 FLIGHT DATA RECORDER (FDR)
All ASD controllers (master controller and individual module controllers)
have a local non-volatile memory that allows the microprocessor to save
relevant operating variables after certain events and/or at a programmable
period controlled by the active master controller.
The data stored in the Flight Data Recorder (FDR) of the master
controller are shown in Table 4-1, the module data are shown in
Table 4-2.
