To perform a ground start ignition to the selected igniter, what position should the engine start lever be in?

• A. IDLE
• B. GRD
• C. FLT
• D. CONT

Answer: (A)

Beginning a ground start requires the ignition system to light off as the starter brings the engine up from zero. Putting the engine start lever in idle sets the ignition circuit for the selected igniter and allows the fuel-air mixture to ignite as the compressor spool increases from rest. The other positions are for different phases of operation (flight or continuous ignition) and do not provide the proper light-off sequence needed for a fresh ground start. So, the correct practice is to have the start lever in idle to perform a ground start ignition to the chosen igniter.
