What aircraft design feature gives an aircraft longitudinal stability?

Thrust line affects longitudinal stability. Power or thrust can also have a destabilizing effect in that an increase of power may tend to make the nose rise. The aircraft designer can offset this by establishing a “high thrust line” wherein the line of thrust passes above the CG.
