The engine block must be connected to the airframe using a properly sized ground strap
for carrying the starter current and to avoid static electricity between the engine and the
airframe.
The minimum cable cross-section for the line from the battery to the starter relay and from
there to the electric starter and for the ground line (start system) depends on the cable
length “I“(= Sum of the supply line and ground line of the electric starter) and has to be cal-
culated according to the following table.
