Ignition smell engine start 738
Hi Guys
Does anyone have any idea what the ignition sort of smell is and where it comes from after engine start that enters the flightdeck on the 737-800.
Someone maybe has a technical explanation?
I have had it numerous times it has always been shrugged off as it dissipates within a matter of seconds.
Bear in mind the packs are off and in standard starting configuration with the Air Cond panel.
Many thanks
