# Coffin Corner

February, 23, 2021 by Luca Caviness

Coffin Corner occurs at an aircraft’s Absolute Ceiling, where the aircraft can neither slow down without stalling nor speed up without exceeding the aircraft’s maximum operating speed. In other words, this is where the stall speed is equal to the max operating speed. It is the only speed, at that certain altitude, that allows a steady and level flight.
