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 Rider and obstacles on the road. The up and down buttons are used to shift gears. Mach Rider's bike has four speeds and shifting to the fourth gear at high speed will grant the player in instant speed boost. Conversely, the player remaining in a higher gear while stopping results in a slower acceleration. In each round, points can be scored by destroying enemies and certain obstacles with the machine gun. The number of points scored for destroying enemies and obstacles is determined by the type of enemy or obstacle destroyed. If the player blocks an attacking enemy by ramming it
