Acceleration is described in units of the force called “Gs.” A pilot in a steep turn may experience forces of acceleration equivalent to many times the force of gravity. This is especially true in military fighter jets and high-performance, aerobatic aircraft where the acceleration forces may be as high as 9 Gs.

How many G's can kill you?
Changes in speed are expressed in multiples of gravitational acceleration, or 'G'. Most of us can withstand up to 4-6G. Fighter pilots can manage up to about 9G for a second or two. But sustained G-forces of even 6G would be fatal.
How many G's can a pilot take?
Fighter pilots can handle greater head-to-toe G forces—up to 8 or 9 G's—and for longer periods by wearing anti-G suits. These specialized outfits use air bladders to constrict the legs and abdomen during high G's to keep blood in the upper body.
What does it mean to pull Gs?
"Pulling X g's" is a fixed expression meaning to operate the aircraft so that the pilot experiences a pull (due to acceleration from the engines or centrifugal force and maybe gravity too) equivalent to X times g.
What speed is G Force?
One G of force is equivalent to 22 miles per hour.
