During a normal Space Shuttle launch, for example, max  value of 0.32 atmospheres occurred at an altitude of approximately , about one minute after launch. The three Space Shuttle Main Engines were throttled back to about 65–72% of their rated thrust (depending on payload) as the dynamic pressure approached max ; combined with the propellant grain design of the solid rocket boosters, which reduced the thrust at max  by one third after 50 seconds of burn, the total stresses on the vehicle were kept to a safe level.
During a typical Apollo mission, the max  (also just over 0.3 atmospheres) occurred between  of altitude; approximately the same values occur for the SpaceX Falcon 9.
The point of max  is a key milestone during a space vehicle launch, as it is the point at which the airframe undergoes maximum mechanical stress.
