Factors and situations that could lead to an inadvertent stall, spin, and loss of control during cruise flight.

Bottom line

Many loss of control in-flight (LOC-I) accidents are the result of stalls, spins, or accelerated maneuvers. Inappropriate use or inadequate monitoring of autoflight modes can be a contributing factor to a stall event. Climbing in vertical speed can lead to a stall event when pilots do not notice the airspeed reducing as the altitude increases.
