CFM56 ENGINES (CFM56-7) 737-600/700/800/900 AIRCRAFT MAINTENANCE MANUAL 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. Abbreviations and Acronyms * CDS - common display system * CDU - control display unit * CONT - continuous * DEU - display electronics unit * EEC - electronic engine control * FLT - flight * FMC - flight management computer * GRD - ground * IGN - ignition * L - left * R - right IGNITION - INTRODUCTION EFFECTIVITY GUN ALL 74-00-00 Page 2 D633A101-GUN Oct 10/2002 BOEING PROPRIETARY - Copyright#- Unpublished Work - See title page for details.
