Mach tuck the speed of sound and control authority both increase. To prevent Mach stall from progressing, the pilot should keep the airspeed below the type's critical Mach number by reducing throttle, extending speed brakes, and if possible, extending the landing gear. A number of design techniques are used to counter the effects of Mach tuck. On both conventional tailplane and canard foreplane configurations, the horizontal stabiliser may be made large and powerful enough to correct the large trim changes associated with Mach tuck. In place of the conventional elevator control surface, the whole stabiliser may be made moveable or "all-flying", sometimes
Mach Five of his father's motor company). In the 1993 American remake, the design was completely changed. Its name probably derives from the fact that speeds above Mach 5 are known as hypersonic. However, the Mach Five cannot reach Mach speeds. The name is also a pun in two languages: the word for "five" in Japanese is "go". However, the "go" used for the car's name is a suffix attached to the names of ships, etc. Thus, the car is known in the Japanese version as simply the "Mach".
