"takeoff" or "take-off"?
Is there a definitive rule for the use of the word "takeoff" or "take-off" in the written form (SOPs or Supp Techniques or Abnormals)? Which version is correct?
In 20 yrs of writing them I'm always taken to task by those who think one or the other is the correct version but I can find a definitive reference source to resolve the question once and for all.
