General
The ignition systems supply electrical sparks in the combustion
chamber for combustion. Each engine has two ignition systems
that operate independently. The ignition system usually
operates manually. However, the ignition systems operate
automatically when the electronic engine control (EEC) sees a
possible engine flameout condition.
You use ignition during these times:
* Ground start
* Takeoff and landings
* In-flight (during heavy turbulence or bad weather)
* In-flight start.

* CONT - continuous
* DEU - display electronics unit
* EEC - electronic engine control

General
These components control ignition:
* Start levers
* Start switches
* Ignition selector switch
* Electronic engine control (EEC).
The start lever controls ignition system power to the EEC. The
start switch and the ignition selector switch supply inputs to the
EEC. The EEC uses these inputs to supply power to the ignition
