Hi everyone,
I'm currently undergoing my A320 rating and I have a question which puzzles me. I've been working the past seven years as an aircraft refuelling operator and most ground staff regularly complains about smokey IAE engines after shut down. Plumes of smoke still emerging after 10-15 minutes. Never seen it on CFM, besides the regular puffs, so I take it it's a design issue. Someone throw me a good explanation besides dripping oil.
