Q1

Igniter plug surface discharge gap wear is monitored because:

A worn igniter plugs produce too much spark energy that can damage the combustion chamber liner from thermal shock cycles

B excessive wear increases the gap beyond the point where the exciter voltage can reliably produce a spark for ignition

C the gap wear rate indicates the health of the exciter unit, with faster wear meaning the exciter is producing too much power
