ELECTRICAL LOAD ANALYSIS (Ela)

12.4.1 Factory-Built Variants

An ELA has been carried out as part of the aircraft's certification basis. Any changes to the electrical
system which affect the ELA require a new ELA to be raised. This work may only be carried out by
Approved Personnel in conjunction with a CAR 35 Authorised Person (or equivalent) Engineering
Order. Note that this applies in Australia – in other countries the local Airworthiness Authority must
be consulted for procedures.
12.4.2 Non Factory-Built Variants

For VFR Daylight only operations, an Electrical Load Analysis is not required as failure of the
electrical generation system would have a limited effect on the length of time of radio transmissions
and no effect on aircraft performance as the engine electrical system is totally isolated from the
power supply and is self-sustaining. The battery is only used to crank the engine for starting.

For other operations the builder / operator must ensure that the electrical system is adequate and
meets all regulatory requirements for the type of operation undertaken.
