The Airbus A340-600 FCOM 1.28.10 (Fuel System Description) talks about Rotor Burst. Could someone briefly explain what this is please.
Here is an extact from the FCOM
ROTOR BURST TRANSFERS
The FCMC enters the rotor burst mode, if both split valves are selected and one engine LP valve is shut. If an inboard engine rotor burst occurs, all automatic transfers directed to the inner tanks are into inner tanks 1 and 4 only.
If an outboard engine rotor burst occurs, all automatic transfers, directed to the inner tanks, are into inner tanks 2 and 3 only.
