Summary 281 Max talks with Catherine Cavagnaro about the Myth of the 70-50 takeoff rule and what’s wrong with it. It seems that 70-50 rule is extracted from a basic but unrealistic model for aircraft takeoffs that ignores air resistance. The same model predicts her Bonanza will go supersonic shortly after takeoff. Even if the rule were valid, a pilot wouldn’t rotate until the last inch of the runway.
