- Avionics Full Duplex Switched Ethernet (AFDX) switch configuration table T53S or T53D (depending on AFDX layer architecture).
NOTE: This operation can be done either manually or using the Smart Dataloading T ool (SDT) function. The SDT will ease and speed-up embodiment of this Service Bulletin, as well as reducing the risk of human errors, by using scripts to automate dataloading and configuration verification operations.
(3) Advantages The main modifications introduced by this Service Bulletin are described hereunder.
Flight Controls (F/CTL):
FCGS new X13 STD includes:
- Primary (PRIM) Flight Control Computer (FCC) STD P13
