Airbus CFM56 5B Engine Anti-ice
A quick question about the CFM56 5B engine anti-ice system. Every aircraft I have ever flown has automatically turned on engine ignition when selecting Engine Anti-ice. According to my companies manuals this is NOT the case with the CFM56-5B engine (see below). My question is this, why does this engine model NOT need engine ignition "on" as a safety precaution against flame-out during anti-ice operation?

Engine Anti-Ice:
• When selected will not automatically turn “on” ignition.
• Do not expect “Ignition” message on ECAM when EAI is selected.
