03-08-50: Engine Start - Battery Power Only
Use this checklist in situations where the only electrical source available is the airplane’s
batteries, and an air source is available from either the APU or external air cart.
This checklist calls for switches to be selected before selecting the Main Batteries to ON.
The intent is to reduce drain on the Main Batteries while performing normal checklist
functions.
If the APU is the source of air for engine start, expedite the steps between starting the
APU and starting the first engine. This reduces drain on the Main Batteries.
Complete all safety checks and as much of Section 03-03-10, Before Starting Engines,
as possible.
