In the ground, or beta range, changes in throttle position affect both fuel flow and propeller blade
angle. Within the ground range, the propeller blade angle ranges from maximum reverse to the
flight idle position. Below the ground idle position, the blade pitch is changed so that the blades
have their leading edge pointing slightly opposite to the direction of flight, allowing reverse
thrust to be developed by the propeller. The C-130 uses this feature to slow the aircraft during
taxi and after landing.

Reverse thrust can be used on the

ground only

. Reverse thrust is used to slow the aircraft during

rejected takeoffs, landings, and during taxi, both to control taxi speed, and for backing the
aircraft up. The ability to back up is important for operations at austere airfields, where there
may be limited ramp space.

Reverse thrust a under static conditions is about 30% of static takeoff power. The effectiveness
of reverse thrust increases with airspeed, so that at 100 knots, reverse thrust is about 60% of
static takeoff power.
