i. A condition in gas turbine engines in which unburned fuel travels past the turbine, resulting in flames traveling down the jet pipe and often being expelled from the nozzle.
ii. A faulty operation in a reciprocating engine in which unburned fuel travels through the exhaust valve and burns in an exhaust pipe. This is normally because of the excessive richness of the fuel-air mixture. More often than not, a visible flame appears beyond the nozzle.
