Background

The purpose of this Safety Enhancement is to reduce the risk of taking off with misconfigured flaps or slats by directing air carriers to review and amend (as necessary) their current Standard Operating Procedures (Standard Operating Procedures (SOPs)) related to setting proper flap/slat configuration for takeoff.

Flight operations data provided by air carriers shows that air carriers that delay takeoff configuration until after initiating taxi have about four times greater likelihood of an attempted flaps-up takeoff.
